Delayed-immediate breast reconstruction

In patients with early-stage breast cancer who are scheduled to undergo mastectomy and desire breast reconstruction, the optimal timing of reconstruction depends on whether postmastectomy radiation therapy will be needed. Immediate reconstruction offers the best aesthetic outcomes if postmastectomy radiation therapy is not needed, but if postmastectomy radiation therapy is required, delayed reconstruction is preferable to avoid potential aesthetic and radiation-delivery problems. Unfortunately, the need for postmastectomy radiation therapy cannot be reliably determined until review of the permanent tissue sections. The authors recently implemented a two-stage approach, delayed-immediate breast reconstruction, to optimize reconstruction in patients at risk for requiring postmastectomy radiation therapy when the need for postmastectomy radiation therapy is not known at the time of mastectomy. Stage 1 consists of skin-sparing mastectomy with insertion of a completely filled textured saline tissue expander. After review of permanent sections, patients who did not require post-mastectomy radiation therapy underwent immediate reconstruction (stage 2) and patients who required postmastectomy radiation therapy completed postmastectomy radiation therapy and then underwent standard delayed reconstruction. In this study, the feasibility and outcomes of this approach were reviewed. Fourteen patients were treated with delayed-immediate reconstruction between May of 2002 and June of 2003. Twelve patients had unilateral reconstruction and two patients had bilateral reconstruction, for a total of 16 treated breasts. All patients completed stage 1. Tissue expanders were inserted subpectorally in 15 breasts and subcutaneously in one breast. The mean intraoperative expander fill volume was 475 cc (range, 250 to 750 cc). Three patients required postmastectomy radiation therapy and underwent delayed reconstruction. Eleven patients did not require postmastectomy radiation therapy. Nine patients had 11 breast reconstructions (stage 2), six with free transverse rectus abdominis musculocutaneous (TRAM) flaps, one with a superior gluteal artery perforator flap, and four with a latissimus dorsi flap plus an implant. The median interval between stages was 13 days (range, 11 to 22 days). Two patients who did not require postmastectomy radiation therapy have not yet had stage 2 reconstruction, one because she wished to delay reconstruction and the other because she required additional tissue expansion before permanent implant placement. Six complications occurred. The stage 1 complications involved two cases of mastectomy skin necrosis in patients who required post-mastectomy radiation therapy; one patient required removal of the subcutaneously placed expander before postmastectomy radiation therapy and the other patient had a subpectorally placed expander that only required local wound care. The stage 2 complications were a recipient-site seroma in a patient with a latissimus dorsi flap, a recipient-site hematoma in the patient with the superior gluteal artery perforator flap, and two arterial thromboses in patients with TRAM flaps. Both TRAM flaps were salvaged. Delayed-immediate reconstruction is technically feasible and safe in patients with early-stage breast cancer who may require postmastectomy radiation therapy. With this approach, patients who do not require postmastectomy radiation therapy can achieve aesthetic outcomes essentially the same as those with immediate reconstruction, and patients who require postmastectomy radiation therapy can avoid the aesthetic and radiation-delivery problems that can occur after an immediate breast reconstruction.     

Anterolateral thigh flap for postmastectomy breast reconstruction

Most postmastectomy defects are reconstructed by use of lower abdominal-wall tissue either as a pedicled or free flap. However, there are some contraindications for using lower abdominal flaps in breast reconstruction, such as inadequate soft-tissue volume, previous abdominoplasty, lower paramedian or multiple abdominal scars, and plans for future pregnancy. In such situations, a gluteal flap has often been the second choice. However, the quality of the adipose tissue of gluteal flaps is inferior to that of lower abdominal flaps, the pedicle is short, and a two-team approach is not possible because creation of the gluteal flap requires that the patient's position be changed during the operation. In 2000, five cases of breast reconstructions were performed with anterolateral thigh flaps in the authors' institution. Two of them were secondary and three were immediate unilateral breast reconstructions. The mean weight of the specimen removed was 350 g in the three patients who underwent immediate reconstruction, and the mean weight of the entire anterolateral thigh flap was 410 g. Skin islands ranged in size from 4 x 8 cm to 7 x 22 cm, with the underlying fat pad ranging in size from 10 x 12 cm to 14 x 22 cm. The mean pedicle length was 11 cm (range, 7 to 15 cm). All flaps were completely successful, except for one that involved some fat necrosis. The quality of the skin and underlying fat and the pliability of the anterolateral thigh flap are much superior to those of gluteal flaps and are similar to those of lower abdominal flaps. In thin patients, more subcutaneous fat can be harvested by extending the flap under the skin. Use of a thigh flap allows a two-team approach with the patient in a supine position, and no change of patient position is required during the operation. However, the position of the scar may not be acceptable to some patients. Therefore, when an abdominal flap is unavailable or contraindicated, the creation of an anterolateral thigh flap for primary and secondary breast reconstruction is an alternative to the use of lower abdominal and gluteal tissues.     

The fate of free flaps used to reconstruct defects in recurrent head and neck cancers

The purpose of this study was to assess free-flap viability in patients treated for recurrent head and neck cancers. A 10-year retrospective review identified 121 patients who had had prior head and neck cancers extirpated for cure, who subsequently presented with documented recurrent cancers that were removed, and who then underwent reconstruction with free flaps. The charts of these patients were reviewed for patient demographics, tumor types, location, flaps used for reconstruction, size of area requiring reconstruction, length of operation, previous radiation, and all postoperative morbidity and mortality. The time to recurrence ranged from 21/2 months to 21 years. The majority of tumors treated were squamous cell carcinomas (n = 82). Most of them were located intraorally (n = 75). Radiation therapy had been delivered to 88 patients before their free-flap reconstructions. In this series, 31 percent of all patients required additional surgery for complications, 14 percent of free flaps were lost, and 4 percent of patients died within 30 days of their operation. The significant findings were that a flap that was >4 cm in diameter was related to flap loss (p = 0.03 by the chi2 method) and that flap loss was related to operative times greater than 11 hours (p = 0.03 by the chi2 method). It was concluded that recurrent head and neck cancers with large postextirpation defects that required prolonged operative times yielded a significantly high tendency toward flap failure.     

The gluteal fasciocutaneous rotation-advancement flap with V-Y closure in the management of sacral pressure sores

The sacral region is one of the most frequent sites of pressure sore development, and local flaps in the gluteal region are usually preferred when surgical closure is needed. The authors used the gluteal fasciocutaneous rotation-advancement flap with V-Y closure to manage sacral pressure sores in 15 patients. The design was a combination of the classic rotation and V-Y advancement flap patterns. When the wound was closed, the tension at the distal end of the rotation flap was relieved by flap advancement and the combined rotation-advancement action was supported laterally with V-Y closure. A wide skin pedicle was preserved at the inferomedial part of the flap. This pedicle augmented the blood supply to the flap skin and kept the surgical incision small, thus helping to reduce the risk of fecal contamination and associated wound-healing problems. This flap can also be converted to any design of fasciocutaneous or musculocutaneous V-Y advancement flap, should such a change be required. The largest defects that were closed with a unilateral rotation-advancement flap and bilateral rotation-advancement flaps were 12 and 18 cm in diameter, respectively. In 1.5 to 35 months of follow-up, none of the patients developed wound dehiscence or flap necrosis requiring repeated surgery. This technique is simple, can be performed quickly, has minimal associated morbidity, and yields a good outcome.     

Free-style free flaps

Free-tissue transfer has become the accepted standard for reconstruction of complex defects. With the growth of this field, anatomic studies and clinical work have added many flaps to the armamentarium of the microvascular surgeon. Further advancements and experience with techniques of perforator flap surgery have allowed for the harvest of flaps in a free-style manner, where a flap is harvested based only on the preoperative knowledge of Doppler signals present in a specific region. Between June of 2002 and September of 2003, 13 free-style free flaps were harvested from the region of the thigh. All patients presented with an oral or pharyngeal cancer and underwent resection and immediate reconstruction of these flaps. All flaps were cutaneous and were harvested in a suprafascial plane. The average size of the flaps was 108 cm2 (range, 36 to 187 cm2), and the average length of the vascular pedicle was 10 cm (range, 9 to 12 cm). All flaps were successful in achieving wound coverage and functional outcomes without any vascular compromise necessitating re-exploration. Free-style free flaps have become a clinical reality. The concepts and techniques used to harvest a free-style free flap will aid in dealing with anatomic variations that are encountered during conventional flap harvest. Future trends in flap selection will focus mainly on choosing tissue with appropriate texture, thickness, and pliability to match requirements at the recipient site while minimizing donor-site morbidity.     

Free-flap reconstruction of large defects of the scalp and calvarium

Beyond a certain size, full-thickness defects of scalp are not amenable to local flap repair. Staged distant flaps have now been virtually eliminated by free-flap reconstruction. The authors present 12 patients in whom full-thickness scalp defects with an average area of 275 cm2 were reconstructed utilizing free flaps. Nine patients had corresponding large calvarial defects. Ten patients had reconstruction with free latissimus dorsi muscle flaps and overlying skin grafts, and one patient had reconstruction with a scapular free flap. Of the 12 patients, 8 had extirpative surgery for tumor with immediate reconstruction and the remaining 4 had reconstruction for chronic radionecrosis of the scalp, usually associated with infected osteoradionecrosis of the calvarium. Of this latter group, 2 patients underwent simultaneous acrylic cranioplasty. The technique and results are discussed.     

The concept of fillet flaps: classification, indications, and analysis of their clinical value

Tissue of amputated or nonsalvageable limbs may be used for reconstruction of complex defects resulting from tumor and trauma. This is the "spare parts" concept.By definition, fillet flaps are axial-pattern flaps that can function as composite-tissue transfers. They can be used as pedicled or free flaps and are a beneficial reconstruction strategy for major defects, provided there is tissue available adjacent to these defects.From 1988 to 1999, 104 fillet flap procedures were performed on 94 patients (50 pedicled finger and toe fillets, 36 pedicled limb fillets, and 18 free microsurgical fillet flaps).Nineteen pedicled finger fillets were used for defects of the dorsum or volar aspect of the hand, and 14 digital defects and 11 defects of the forefoot were covered with pedicled fillets from adjacent toes and fingers. The average size of the defects was 23 cm2. Fourteen fingers were salvaged. Eleven ray amputations, two extended procedures for coverage of the hand, and nine forefoot amputations were prevented. In four cases, a partial or total necrosis of a fillet flap occurred (one patient with diabetic vascular disease, one with Dupuytren's contracture, and two with high-voltage electrical injuries).Thirty-six pedicled limb fillet flaps were used in 35 cases. In 12 cases, salvage of above-knee or below-knee amputated stumps was achieved with a plantar neurovascular island pedicled flap. In seven other cases, sacral, pelvic, groin, hip, abdominal wall, or lumbar defects were reconstructed with fillet-of-thigh or entire-limb fillet flaps. In five cases, defects of shoulder, head, neck, and thoracic wall were covered with upper-arm fillet flaps. In nine cases, defects of the forefoot were covered by adjacent dorsal or plantar fillet flaps. In two other cases, defects of the upper arm or the proximal forearm were reconstructed with a forearm fillet. The average size of these defects was 512 cm2. Thirteen major joints were salvaged, three stumps were lengthened, and nine foot or forefoot amputations were prevented. One partial flap necrosis occurred in a patient with a fillet-of-sole flap. In another case, wound infection required revision and above-knee amputation with removal of the flap.Nine free plantar fillet flaps were performed-five for coverage of amputation stumps and four for sacral pressure sores. Seven free forearm fillet flaps, one free flap of forearm and hand, and one forearm and distal upper-arm fillet flap were performed for defect coverage of the shoulder and neck area. The average size of these defects was 432 cm2. Four knee joints were salvaged and one above-knee stump was lengthened. No flap necrosis was observed. One patient died of acute respiratory distress syndrome 6 days after surgery.Major complications were predominantly encountered in small finger and toe fillet flaps. Overall complication rate, including wound dehiscence and secondary grafting, was 18 percent. This complication rate seems acceptable. Major complications such as flap loss, flap revision, or severe infection occurred in only 7.5 percent of cases. The majority of our cases resulted from severe trauma with infected and necrotic soft tissues, disseminated tumor disease, or ulcers in elderly, multimorbid patients.On the basis of these data, a classification was developed that facilitates multicenter comparison of procedures and their clinical success. Fillet flaps facilitate reconstruction in difficult and complex cases. The spare part concept should be integrated into each trauma algorithm to avoid additional donor-site morbidity and facilitate stump-length preservation or limb salvage.     

Microsurgical scalp reconstruction in the patient with cancer

The literature regarding reconstruction of large scalp wounds with free tissue transfer consists mostly of case reports and small series, and none of the published reports focus on the particular problems of the oncology patient. Here the authors describe their experience with 37 flaps in 32 patients, all of whom required scalp reconstruction with free tissue transfer after tumor extirpation. Twenty-seven free flaps were performed at the time of the initial surgery and 10 were performed after a prior reconstruction failed. The authors describe the characteristics of the patients and procedures, including tumor type, wound size and complexity, flaps and recipient vessels used, preoperative and postoperative radiation therapy, and complications. Most (72 percent) of the tumors were recurrent or persistent. The free tissue transfer was successful in all patients. There was a 59 percent overall complication rate with 32 percent of patients requiring a secondary surgical procedure. Most of the complications were wound-healing complications. Although there were two cases of vein thrombosis, these were salvaged by revision, and no flaps were lost. Nine patients underwent postoperative radiation therapy that was well tolerated. Only four patients underwent cranioplasty at the time of the initial operation, and no secondary cranial reconstructions were performed. The authors conclude that preoperative and postoperative radiation therapies as well as the need for expedient tumor resection and immediate flap coverage are issues that make free tissue transfer attractive for the oncology patient who needs scalp reconstruction. Although the complication rate is relatively high and a significant percentage of patients require a secondary procedure, free flap coverage was efficacious for all patients in this group. Cranioplasty is not usually required but, if needed, alloplastic or autologous cranial reconstruction does not appreciably increase morbidity in the selected patient.     

Free split-cutaneous perforator flaps procured using a three-dimensional harvest technique for the reconstruction of postburn contracture defects

With recent advances in free-tissue transfer, microsurgical techniques have been used more frequently for the reconstruction of postburn contracture defects. Traditional methods, including full-thickness skin grafts and local flaps, often result in a good outcome; however, multiple operative procedures, long periods of splinting, and physical rehabilitation are often required. Free split-cutaneous perforator flaps, consisting of one large cutaneous paddle with two perforating vessels split into two separate skin regions, were used for two kinds of postburn contractures: rectangular and spatially separate defects. From September of 2000 to October of 2002, seven patients underwent this method of reconstruction at Chang Gung Memorial Hospital in Taiwan. A three-dimensional flap harvest method, in which the skin paddle is circumferentially elevated early in the harvest, was used. Postburn scar contractures had resulted from flame burns in six cases and an electric burn in one case. The reconstructive regions included the neck in two patients, the breast in one patient, and the hand in four patients. There were six male patients and one female patient, with a mean age of 34.8 years (range, 25 to 49 years). The size of the excised scar ranged from 120 cm2 to 308 cm2 (mean, 162.3 cm2). The size of the unsplit flaps ranged from 144 cm2 to 337.5 cm2 (mean, 192.1 cm2). The average time for flap harvest using this three-dimensional harvest technique was 39.1 minutes. The average total operative time was 4.3 hours. The average total hospital stay was 7.3 days (range, 6 to 11 days). All flaps survived without major complications. The donor site was closed primarily in all cases. At a mean follow-up time of 9 months, the functional and aesthetic outcomes showed significant improvement as compared with the preoperative condition. In this study, a new method of flap harvest using a three-dimensional technique is introduced, and its application in the reconstruction of postburn contractures is evaluated.     

Reconstructive management of cranial base defects after tumor ablation

Successful reconstruction after cranial base tumor ablation is paramount in preventing potentially life-threatening complications. The purpose of this study was to evaluate experiences of cranial base reconstruction and to identify reconstructive management principles that may assist in achieving successful cranial base reconstruction. All cranial base reconstructions performed by the Department of Plastic Surgery at the University of Texas M. D. Anderson Cancer Center between January of 1993 and September of 1999 were reviewed. Analyses were performed to assess the impact of location of defect, type of reconstruction, type of dural repair, and history of preoperative radiation and chemotherapy on rates of complications, and patient survival. The 77 patients who underwent cranial base reconstruction after tumor ablation during the study period had a mean age of 52 years (6 to 84 years). The mean follow-up period was 28.7 months (1 to 76 months). Squamous cell carcinoma, the most common histopathologic type, was present in 24 patients (31 percent), and 35 patients (45 percent) presented with recurrent disease. Location of defects involved region I (anterior) in 31 patients (40 percent), region II (anterior-lateral) in 18 (23 percent), region III (lateral-posterior) in six (8 percent), and more than one region in 22 (29 percent). Reconstructive methods included free flaps in 52 patients (68 percent), temporalis muscle flaps in 14 (18 percent), pericranial flaps in eight (10 percent), and other local flaps (two galeal, one scalp) in three (4 percent). Of the 52 free flaps, 18 (35 percent) were used in region I, 14 (27 percent) in region II, six (12 percent) in region III, and 14 (27 percent) in defects involving more than one region. Of the 14 temporalis muscle flaps, 13 (93 percent) were used for defects involving regions I or II and one (7 percent) was used for a defect involving region III. Of the 11 pericranial and other local flaps, nine (82 percent) were used in region I, one (9 percent) in region II, and one (9 percent) in a combination of regions II and III. Complications occurred in 21 patients (27 percent): three total flap losses (4 percent), three partial flap losses (4 percent), two cerebrospinal fluid leaks (3 percent), two cases of meningitis (3 percent), two abscesses (3 percent), five cases of delayed wound healing (6 percent), two hematomas (3 percent), one wound infection (1 percent), and one cerebrovascular accident (1 percent). Overall survival was 77 percent at 2 years and 58 percent at 4 years. The type of reconstruction, location of defect, type of dural repair, and history of preoperative radiation and chemotherapy had no significant association with the incidence of complications. Neither the type of reconstruction nor the location of defect showed a significant effect on patient survival. In this experience, local flaps, such as pericranial or temporalis muscle flaps, are good choices for reconstruction of smaller anterior or lateral cranial base defects. For defects that require larger amounts of soft tissue, free flaps are appropriate. With proper patient selection, successful cranial base reconstruction can be performed with either local or free flaps with a low incidence of complications.     

Gluteal perforator flaps for coverage of pressure sores at various locations

Flap coverage is essential for successful treatment of pressure sores, and musculocutaneous flaps have been preferred universally. Development of perforator flaps supplied by musculocutaneous perforators has allowed reconstructive surgeons to harvest flaps without including muscles. Perforator flaps have enhanced the possibility of donor sites because a flap can be supplied by any musculocutaneous perforator, and donor-site morbidity is also reduced. Between November of 1998 and June of 2002, the authors used 35 gluteal perforator flaps in 32 consecutive patients for coverage of pressure sores located at sacral (n = 22), ischial (n = 7), and trochanteric (n = 6) regions. The mean age of the patients was 53.1 years (range, 5 to 87 years), and there were 16 male and 16 female patients. All flaps in this series were supplied by musculocutaneous arteries arising from gluteal muscles. Patients were followed up for a mean period of 13.6 months. Wound dehiscence was observed in two patients and treated by secondary closure. Three patients died during the follow-up period. All flaps survived except one that had undergone total necrosis, and only one recurrence was noted during the follow-up period. Gluteal perforator flaps are safe and reliable options for coverage of pressure sores located at different locations. Freedom in flap design and low donor-site morbidity make gluteal perforator flaps an excellent choice for pressure sore coverage.     

Complications after reconstruction by plate and soft-tissue free flap in composite mandibular defects and secondary salvage reconstruction with osteocutaneous flap

Reconstruction of composite defects of the mandible is a challenging problem. Although the use of an osteocutaneous free flap, alone or in combination with another soft-tissue free flap, is generally accepted to be optimal, the bony reconstruction is sometimes undervalued, especially when the cancer is advanced. In such situations, reconstruction is often performed with a reconstruction plate covered with a soft-tissue free flap. Between January of 1997 and July of 2000, 80 patients with composite or extensive composite oromandibular defects underwent treatment with a reconstruction plate and a soft-tissue free flap. All of the patients were male, and the ages of the patients at the time of treatment ranged from 32 to 78 years (mean, 51 years). Tumors were classified as stage IV in 56 patients (70 percent), whereas the remaining 24 patients (30 percent) had recurrent carcinomas. The titanium mandibular reconstruction system manufactured by Stryker (Freiburg, Germany) was used to bridge the mandibular defects. The soft-tissue free flaps used for wound and plate coverage were as follows: anterolateral thigh flap (n = 75), radial forearm flap (n = 3), transverse rectus abdominis myocutaneous flap (n = 1), and tensor fasciae latae flap (n = 1). Five patients with recurrent carcinomas and 10 with stage IV carcinomas (18.75 percent) died 2 to 6 months after the operation and were excluded from the study. The remaining 65 patients were monitored for an average follow-up period of 22 months (range, 6 to 40 months). During that period, one or more complications occurred for 45 patients (69.2 percent). Plate exposure was the most common complication and was observed for 30 patients (46.15 percent). Twenty of the 65 patients (30.8 percent) required secondary salvage reconstruction with a fibula osteoseptocutaneous flap. The decision to perform a secondary salvage procedure was based on the general health of the patient, the extent of local disease, and the severity of the complications. Patients underwent salvage operations after an average of 11.5 months (range, 6 to 26 months). The major reasons for the second operation were as follows: reconstruction plate exposure (n = 12), soft-tissue deficiency and mandibular contour deformation of the lateral face (n = 7), intraoral contracture and lack of a gingivobuccal sulcus (n = 6), trismus (n = 4), and osteoradionecrosis of the mandible (n = 2). The total flap survival rate was 90 percent (18 of 20 free flaps). In two cases, the skin paddles of the fibula osteoseptocutaneous flaps exhibited partial failure and were revised with pedicled pectoralis major and deltopectoral flaps. The reconstruction plate and free soft-tissue flap procedure for the reconstruction of composite defects of the oromandibular region has many late complications, which eventually necessitate reconstruction of the mandible with an osteocutaneous free flap.     

Reconstruction of concomitant lip and cheek through-and-through defects with combined free flap and an advancement flap from the remaining lip

Massive facial defects involving the oral sphincter are challenging to the reconstructive surgeon. This study presents the authors' approach to simultaneous reconstruction of complex defects with an advancement flap from the remaining lip and free flaps. From January of 1997 to December of 2001, 22 patients were studied following ablative oral cancer surgery. Their ages ranged from 32 to 66 years. Nineteen patients had buccal cancer, two patients had tongue cancer, and one patient had lip cancer. In all cases, the disease was advanced squamous cell carcinoma. Nine patients underwent composite resection of tumor with segmental mandibulectomy, and seven patients underwent marginal mandibulectomy. Cheek defects ranged from 15 x 12 cm to 4 x 3 cm, and intraoral defects ranged from 14 x 8 cm to 5 x 4 cm in size. One third of the lower lip was excised in nine patients, both the upper and lower lips were excised in 10 patients, and only commissure defects were excised in three patients. An advancement flap from the remaining upper lip was used for reconstruction of the oral commissure and oral sphincter. Then, the composite through-and-through defect of the cheek was reconstructed with radial forearm flaps in 13 patients, fibula osteocutaneous flaps in five patients, double flaps in three patients, and an anterolateral thigh flap in one patient. The free flap survival rate was 96 percent, and only one flap failed. With regard to complications, there were two patients with cheek hematoma, six patients with orocutaneous fistula or neck infection, and one patient with osteomyelitis of the mandible. All but one patient had adequate oral competence. All patients had an adequate oral stoma and could eat a regular or soft diet; two patients could eat only a liquid diet. For moderate lip defects, immediate reconstruction of complex defects took place using an advancement flap from the remaining lip to obtain a normal and functional oral sphincter; the free flap can be used to reconstruct through-and-through defects. This simple procedure can provide patients with a useful oral stoma and acceptable cosmesis.     

Extended vertical trapezius myocutaneous flap in head and neck reconstruction as a salvage procedure

In surgical treatment of head and neck cancer, when local tumor recurrence or failure of the previous reconstruction method occurs, reoperation for reconstruction of complicated soft-tissue defects can become a challenge for the plastic surgeon. This article describes the authors' experience with the extended vertical trapezius myocutaneous flap for head and neck complicated soft-tissue defects in nine patients ranging in age from 17 to 72 years. The causes of the defects were squamous cell carcinoma of the external ear (n = 2), lip (n = 2), larynx (n = 1), and oral cavity floor (n = 1); congenital hemifacial atrophy-temporomandibular joint ankylosis (n = 1); synovial sarcoma at the mandibular ramus (n = 1); and malignant fibrous histiocytoma at the posterior cranial fossa (n = 1). Eight of the nine patients had previously been operated on using other flap procedures, including free flaps and/or distant pedicled flaps (pectoralis major and deltopectoral flaps). One patient had been operated on using a graft procedure. After failure of the previous flap procedures in four patients and tumor recurrence in five patients, the extended vertical trapezius myocutaneous pedicled flap was used as a salvage procedure. The mean flap size was 7 x 34 cm. The flap was based solely on the transverse cervical artery. Superior muscle fibers of the trapezius were preserved and the caudal end of the flap was extended from 10 to 13 cm beyond the caudal end of the trapezius muscle. Three weeks postoperatively, the pedicle was separated. No flap failure occurred. The donor sites were closed primarily. There were no disabilities with regard to shoulder motion. Tumor recurrence was observed in two patients. In conclusion, for complicated soft-tissue defects of the head and neck, the extended vertical trapezius flap can be preferred as a salvage procedure because it is a simple, reliable, large flap that is located far enough from the damaged area.     

Staged breast reconstruction with saline-filled implants in the irradiated breast: recent trends and therapeutic implications

A retrospective review was performed of one surgeon's experience with 40 consecutive patients who had undergone two-stage saline-filled implant breast reconstruction and radiation during the period from 1990 through 1997. A randomly selected group of 40 other two-stage saline-filled implant breast reconstructions from the same surgeon and time period served as controls. This review was undertaken because of the absence of specific information on the outcome of staged saline implant reconstructions in the radiated breast. Previously published reports on silicone gel implants and radiation have been contradictory. At the same time, the criteria for the use of radiation in the treatment of breast cancer have been expanded and the numbers of reconstruction patients who have been radiated are increasing dramatically. For example, in a 1985 report on immediate breast reconstruction, only 1 of 185 patients over a 6-year period underwent adjuvant radiation therapy, whereas in this review, there were 40 radiated breasts with saline-filled implants, 19 of which received adjuvant radiation therapy during their expansion. The study parameters included patient age, breast cup size, implant size, length of follow-up, number of procedures, coincident flap operations, Baker classification, complications, opposite breast procedures, pathologic stage, indications for and details about the radiation, and outcomes. The use of radiation in this review of reconstructed breasts can logically be divided into four groups: previous lumpectomy and radiation (n = 7), mastectomy and radiation before reconstruction (n = 9), mastectomy and adjuvant radiation during reconstruction/expansion (n = 19), and radiation after reconstruction (n = 5). The largest and most rapidly growing group of patients is of those receiving postmastectomy adjuvant radiation therapy. A total of 47.5 percent (19 of 40) of radiated breasts with saline implants ultimately needed the addition of, or replacement by, a flap. Ten percent of a control group with nonradiated saline implant reconstructions also had flaps, none as replacements. Fifty percent or more of both the radiated and control groups had contralateral surgery. Complications were far more common in the radiated group; for example, there were 32.5 percent capsular contractures compared with none in the control group. The control nonradiated implant-only group and the flap plus implant radiated group did well cosmetically. The radiated implant-only group was judged the worst. The increasing use of radiation after mastectomy has important implications for breast reconstruction. The possibility for radiation should be thoroughly investigated and anticipated preoperatively before immediate breast reconstruction. Patients with invasive disease, particularly with large tumors or palpable axillary lymph nodes, are especially likely to be encouraged to undergo postmastectomy radiation therapy. The indications for adjuvant radiation therapy have included four or more positive axillary lymph nodes, tumors 4 cm (or more) in diameter, and tumors at or near the margin of resection. More recently, some centers are recommending adjuvant radiation therapy for patients with as few as one positive lymph node or even in situ carcinoma close to the resection margin. The use of latissimus dorsi flaps after radiation has proven to be an excellent solution to postradiation tissue contracture, which can occur during breast expander reconstruction. The use of the latissimus flap electively with skin-sparing mastectomy preradiation is probably unwise, unless postmastectomy radiation is unlikely. Skin-sparing mastectomy with a latissimus flap thus should be preserved for patients unlikely to undergo adjuvant radiation therapy. Purely autologous reconstruction such as a TRAM flap is another option for these patients, either before or after radiation therapy.     

Reconstruction of the radiated partial mastectomy defect with autogenous tissues.

As conservative surgery and radiation therapy have become accepted treatments for early-stage breast cancer, increasing attention has focused on the cosmetic results of this technique. When partial mastectomy--a term which encompasses a diversity of excisional techniques--is followed by radiation therapy, breast defects characterized by parenchymal loss, nipple-areola complex distortion, and cutaneous abnormalities can occur. From 1981 to 1990, eight patients sought reconstructive correction of a radiated partial mastectomy deformity. Patients were from 42 to 70 years of age (mean 49 years). All had breast cancer, except for one patient with diffuse and chronic breast abscesses. Six patients were reconstructed with latissimus dorsi flaps and two with rectus flaps. No patient underwent reconstruction sooner than 1 year after completion of radiation therapy; for the entire group, a mean of 2.6 years elapsed from completion of radiation therapy to flap reconstruction of the breast. Mammograms were obtained on all the breast cancer patients before and after the myocutaneous flap procedure. Follow-up extended from 1 to 9 years after reconstruction (mean 3.6 years) and included both physical examination and serial mammographic evaluations. Myocutaneous flap reconstruction with either latissimus or rectus flaps achieved an aesthetic improvement of the partial mastectomy deformity in all eight patients. Complications consisted only of seroma formation in two patients following latissimus flap reconstruction. Mammographic evaluation revealed fibrofatty degeneration of the soft tissues of both types of flaps, a change that occurs as early as 6 months after operation and appears as a radiolucent area. The feasibility of mammography as a screening adjunct for recurrent cancer in this group of patients is demonstrated. Advantages of this technique of autogenous tissue reconstruction are improvement of contour deformities associated with conservative surgery and radiation therapy, preservation of normal, sensate breast skin, enhancement of symmetry with the contralateral breast, and avoidance of a prosthesis.     

Free filet extremity flap: indications and options for reconstruction

Radical and extended forequarter and hind limb amputations have been used for curative and palliative intents. Concerns regarding wound healing and closure, especially in irradiated fields, have occasionally limited the extent of ablation. This article reports an experience with coverage of these large defects by using the free filet extremity flap. A retrospective review was performed of 11 patients who had undergone immediate reconstruction with free filet extremity flaps between 1991 and 1998. There were nine men and two women with an average age of 43.9 years. All except three patients received preoperative radiotherapy. Resections included four hindquarter and seven forequarter amputations for palliation of intractable pain, tissue necrosis, and infections. Donor vessels included the brachial artery, its venae comitantes, cephalic and basilic veins, and common femoral and popliteal vessels. Immediate reconstruction was successful in all cases by the use of the amputated limb as the free filet flap. All wounds healed despite irradiation inclusive of defects up to 50 cm x 70 cm (3500 cm2). The average follow-up time was 5 months with a mean survival of 3.5 months. Four patients currently are alive, and one patient died within 30 days of surgery. The remaining six patients have died of their disease within 9 months of the palliative procedures. Pain, tissue necrosis, and infections were improved in all patients after hospital discharge. Extensive defects can be reconstructed and healed successfully, even in irradiated wounds, with the use of the free filet extremity flap. Appropriate advanced preoperative and intraoperative planning is essential. Although survival was unchanged, this technique allowed healed wounds with an improvement in the quality of life.     

Bilateral autogenous breast reconstruction using perforator free flaps: a single center's experience

The authors present a single center's experience in bilateral breast reconstruction using perforator free flaps. The aim of this study was to show their indications, surgical technique, and results. A series of 53 patients underwent this procedure between February of 1996 and October of 2002. The surgical procedures were performed on patients with bilateral breast cancer (11 patients), patients with unilateral breast cancer and contralateral prophylactic mastectomy (22 patients), patients who had undergone bilateral prophylactic mastectomy (18 patients), a patient with Poland's syndrome, and a patient whose aesthetic breast augmentation had failed. Primary and secondary bilateral breast reconstructions were done in 18 and four patients, respectively. Eighteen patients who had earlier undergone breast reconstruction with implants had a tertiary breast reconstruction. Combined reconstruction (primary with secondary and primary with tertiary reconstruction) was done in 13 patients. Ninety-eight deep inferior epigastric perforator flaps and eight superior gluteal artery perforator flaps were used. The average operative time was 10 hours (range, 8 to 14.5 hours) for the simultaneous bilateral reconstruction. Total flap necrosis occurred in two cases (one deep inferior epigastric perforator flap and one superior gluteal artery perforator flap). Partial flap necrosis was not encountered, and fat necrosis was found in one deep inferior epigastric perforator flap (1 percent). Two pulmonary infections, one deep vein thrombosis, and one cardiac arrhythmia occurred as postoperative complications. The mean hospital stay was 9 days (range, 6 to 20 days). Abdominal bulging was reported in one patient. There were no recurrent disease or cancer manifestations, with an average follow-up of 3.5 years. This series clearly shows that perforator flaps are reliable and useful tools for bilateral breast reconstruction. This technique decreases the donor-site morbidity and offers an excellent aesthetic and long-term outcome and high patient satisfaction.     

Anterolateral thigh flap in the treatment of postburn flexion contractures of the knee

The use of the anterolateral thigh fasciocutaneous flap in the reconstruction of soft-tissue defects around the knee among burn patients is described. The anterolateral thigh fasciocutaneous flap was used for eight patients (all male; mean age, 45 years; age range, 32 to 60 years). Flexion contracture was observed for seven patients with unhealed wounds and one patient with a healed burn wound. The anterolateral thigh flap was used as a free flap for six patients and as a distally based island flap for two patients. The flaps ranged from 8 to 17 cm in width and from 12 to 30 cm in length. Seven flaps were based on a musculocutaneous perforator, and two of them were thinned before transfer to the defect. A true septocutaneous perforator was observed in only one case. The mean follow-up period was 12.5 months (range, 3 to 23 months). Only one flap exhibited distal superficial necrosis, which did not compromise the final result. All patients returned to ambulatory status in 15 to 22 days. Extensor splints were applied to prevent mobilization of the skin graft at the flap donor site for only 7 days. The anterolateral thigh flap has many advantages for the reconstruction of postburn flexion contracture of the knee, as follows: (1) very large thin flaps can be elevated, (2) the two-team approach is possible, (3) color and texture matches are good, (4) the donor-site scar can be easily hidden, and (5) the technique allows early mobilization and patients can return to normal daily activity in a short time. Free or distally based anterolateral thigh flaps are a good choice, both aesthetically and functionally, for the reconstruction of soft-tissue defects of the knee region.
