Immediate breast reconstruction using a laparoscopically harvested omental flap

Use of an omental flap to reconstruct the breast after cancer surgery was first reported by Kiricuta in 1963. Since then, the omentum has been widely used in cancer surgery to cover extensive thoracic defects associated with radionecrosis. In contrast, for breast reconstruction or augmentation mammaplasty, rectus abdominis and latissimus dorsi flaps have been used far more often than omental flaps. This article describes a new technique for immediate breast reconstruction using laparoscopically harvested omentum and reports the results obtained in 10 patients. Nine patients underwent immediate breast reconstruction after subcutaneous mastectomy. In the other patient, omentum was used in combination with skin grafting to cover a postmastectomy defect. Follow-up exceeded 16 months in the first patients. The results suggest that breast reconstruction using a laparoscopically harvested omental flap may be extremely dependable in terms of vascular supply (there was one case of partial necrosis, which healed with local management alone). The postoperative course of all patients was uneventful, and the use of laparoscopy reduced the hospital stay to less than 7 days. Donor-site scars were minimal. There was no residual loss of function, and there were no cases of incisional ventral hernia. Cosmetic results were satisfactory, with a soft breast that was both natural in appearance and stable in volume. However, in two patients the amount of omentum was found to be inadequate during the procedure; consequently, an implant was inserted under the omental flap. Breast reconstruction using a laparoscopically harvested omental flap is a new technique that allows autogenous reconstruction without disfigurement of the do-nor site and that results in a soft, natural-looking breast.     

Evaluation of the factors related to postmastectomy breast reconstruction

A retrospective study was conducted in 75 consecutive patients requiring postmastectomy breast reconstruction over a period of 30 months. Each woman was offered one of the following four reconstructive options: free transverse rectus abdominis musculocutaneous flap (total number of reconstructions, n = 34); latissimus dorsi musculocutaneous flap (with or without expander and implant, n = 14); endoscopically assisted harvest of the latissimus dorsi muscle (with expander and implant, n = 13); and application of expander and implant only (n = 12).Of those patients originally selected for retrospective study, six did not meet the short-term prognostic criteria, and concerted attempts to contact two others proved unsuccessful. The remaining 67 patients were examined for the clinically assessed aesthetic appearance of the reconstructed breast(s), the subjective self-assessment of patient satisfaction, and the possible development of postoperative complications. Of these patients, six required bilateral surgery, which accounts for a final sample size of 73 individual breast reconstructions. The 67 individual patients were assessed after a minimum time of 6 months postreconstruction and became the sampling units for analysis.The free transverse rectus abdominis musculocutaneous flap procedure was the preferred method of breast reconstruction in 34 of 73 patients (47 percent), provided that it was generally agreed that the patient could endure a prolonged operation and that there was sufficient unscarred abdominal tissue available. Thereafter, postmastectomy radiotherapy at the chest wall became the primary criterion for assignment of a patient to a particular surgical procedure. Whenever radiotherapy resulted in poor-quality skin at the chest wall, endoscopically assisted transfer of latissimus dorsi muscle flap was considered to be the optimal treatment (13 of 73 patients, or 18 percent). Body mass index and smoking were secondary factors that were taken into account when this alternative technique was being considered.In the absence of radiotherapy, and provided that the chest wall was minimally scarred, patients who were reluctant to have reconstruction with autologous tissue were treated with expander and implant only (12 of 73, or 16 percent). This third procedure is a physically less arduous ordeal for the patient and was therefore the choice for all patients for whom a prolonged operation was not a realistic option. The fourth (and final) surgical procedure, latissimus dorsi musculocutaneous flap (with or without expander and implant), was selected for all patients with a better quality of skin over the chest wall, those whose abdomen was extensively scarred, and those who were on a general surgeon's operating list to undergo immediate breast reconstruction after mastectomy (14 of 73, or 19 percent).Equally good aesthetic results could be demonstrated with each of the four treatment options, provided that the reconstructive procedure selected was optimal for the individual patient and in accordance with the criteria described above. A variety of potential risk factors were considered for association with postoperative complications, including prescribed medication, obesity, smoking behavior, use of radiotherapy, and the recorded aggregated operative time. Of these, only body mass index (p < 0.001) and use of steroids (p = 0.016) were identified as having statistically significant effects on the incidence of adverse events.Finally, the general level of satisfaction expressed by the patient was highly correlated with a good appearance of the reconstructed breast, the physical comfort experienced while wearing a brassiere, and the general mobility of the unsupported reconstruction.     

Modified autogenous latissimus breast reconstruction and the box top nipple

During the past 3 years, the authors have been using the modified autogenous latissimus myocutaneous flap (MALF) for breast reconstruction in increasing numbers because of occasional patient and surgeon dissatisfaction with other methods of breast reconstruction. They have found this method to have unprecedented reliability, making it preferable to other forms of reconstruction in many patients. Considering the very low morbidity, the high patient satisfaction, and current economic factors, the authors are strong advocates of this form of reconstruction. A procedural outline proposed by McCraw and coworkers is followed, with some useful modifications. An elliptical transverse skin paddle is centered over the back fat roll. The area of the skin ellipse measures approximately 8 +/- 2 cm vertically and 30 +/- 5 cm transversely. After making the skin incision, a feathering technique is used in all directions through the fatty layer overlying the latissimus and in the tissue beyond the anteroposterior borders of the latissimus (not beyond 5 cm from the skin incision). By means of feathering, the shape of a breast mound can be created in the allowable tissue supported by the latissimus. A 180-degree rotation of the flap allows dependentvenous drainage and more bulk in the inferior outer quadrant, where it is needed. In the current series of 47 modified autogenous latissimus breast reconstructions, seromas were common. Other complications included one wound infection, one ulnar neuropraxia, and one fat necrosis. There were no flap necroses (partial or complete) or hematomas. The rarity of complications supports the use of this technique in selected patients. An innovative new technique for nipple reconstruction is also described. The "box top technique" of nipple reconstruction consists of four deepithelialized local flaps covered with a skin graft from the groin.     

Double-pedicle transverse rectus abdominis myocutaneous flap for unilateral breast and chest-wall reconstruction

Fifteen patients underwent unilateral breast and chest-wall reconstruction by a double-pedicle transverse rectus abdominis myocutaneous flap technique. Criteria for using both pedicles include (1) exceptionally large soft-tissue requirements, (2) prior abdominal operations compromising the vasculature to portions of the anterior abdominal wall, and (3) certain higher-risk patients with suspected microvascular pathology. Double pedicles allowed the transfer of the skin island as one unit or as two independent hemiellipses of tissue. Follow-up time ranges from 4 to 17 months. Complications included partial tissue loss in two patients, one abdominal flap seroma, and one patient with a hernia.     

Breast reconstruction using tissue expanders and implants in Hodgkin's patients with prior mantle irradiation.

Women treated for Hodgkin's disease with mantle irradiation have an increased risk for developing breast cancer. Typically, breast malignancy in Hodgkin's patients presents bilaterally in a younger age group. Skin flap ischemia, poor skin expansion, implant extrusion, capsular contracture, and poor cosmesis are common sequelae of tissue expander/implant breast reconstruction after breast irradiation for failed breast conservation therapy. This has led most surgeons to favor autologous tissue reconstruction in this setting. This study was performed to determine the efficacy of tissue expander/implant breast reconstruction in breast cancer patients who have been treated with prior mantle irradiation for Hodgkin's disease. A retrospective analysis of all breast cancer patients with a history of Hodgkin's disease and mantle irradiation treated with mastectomy and tissue expander/implant reconstruction between 1992 and 1999 was performed. There were seven patients, with a mean age of 35 years (range, 28 to 42 years). The average interval between mantle irradiation and breast cancer diagnosis was 16 years (range, 12 to 23 years). All patients underwent two-stage reconstruction. Textured surface tissue expanders were placed in a complete submuscular position at the time of mastectomy. Expansion was initiated 2 weeks after insertion and continued on a weekly basis until completion. Expanders were replaced with textured surface saline-filled implants as a second stage. Patients were evaluated for skin flap ischemia, infection, quality of skin expansion, implant extrusion, capsular contracture, rippling, symmetry, and final aesthetic outcome. Breast cancer was bilateral in five patients and unilateral in two. Two patients did not undergo simultaneous bilateral breast reconstruction because of metachronous cancer development. One of the patients had an initial transverse rectus abdominis muscle flap breast reconstruction, followed by a tissue expander/implant reconstruction of the opposite breast. The average follow-up was 3 years. Complications were limited to one case of cellulitis after implant placement that resolved with intravenous antibiotics. There were no cases of skin flap ischemia, poor skin expansion, or implant extrusion. Overall patient satisfaction was high and revisions were not requested or required. Symmetry was best achieved with bilateral implants. This study demonstrates the efficacy of tissue expander/implant breast reconstruction in patients treated with prior mantle irradiation. In this series, tissue expansion was reliable with low morbidity. Second-stage placement of permanent implants yielded good aesthetic results without significant capsular contracture. Mantle irradiation did not appear to compromise the prosthetic breast reconstruction. Tissue expander/implant breast reconstruction should remain a viable option in this category of irradiated patients.     

Use of the latissimus dorsi myocutaneous island flap for reconstruction in the head and neck area: case report.

Cadaver dissection indicated that a large amount of tissue could be transferred in one stage to the head and neck by a latissimus dorsi myocutaneous island flap tunneled beneath a pectoral skin bridge. A clinical trial of this flap (for one-stage reconstruction of a patient after excision of a recurrent mandibular carcinoma and a neck dissection) was successful. Previous investigators have found the myocutaneous latissimus dorsi flap to be dependable and adaptable in reconstructions of the chest wall, breast, and shoulder. It is evident now that the flap also has value in reconstructions of the head and neck.     

Extended V-Y latissimus dorsi musculocutaneous flap for anterior chest wall reconstruction

Patients presenting advanced breast tumors are usually subject to major resections of the anterior chest wall tissue. Flaps taken from the abdominal wall, such as the TRAM, the external oblique flap, and the thoracoabdominal flap are frequently used for closure of this type of lesion. In this study, a different shape was planned for the skin island from the latissimus dorsi musculocutaneous flap with primary closure in V-Y for the correction of major lesions in the anterior chest wall after mastectomies occasioned by advanced breast cancer. The technique was used on eight female patients, between November of 1998 and July of 1999, victims of advanced breast cancer, who had been submitted to radical mastectomies with major resections of the cutaneous tegument. It was possible to make primary closure of lesions in the anterior chest wall, the preoperative areas of which varied between 15 x 15 and 29 x 14 cm (vertical x horizontal). This technical variant permitted use of the flap without the need to create tunnels for its advancement and rotation. It also proved to be easy to perform and presented a low morbidity rate, with three patients presenting minor complications that did not require correction through any further surgical intervention. Closure was obtained in the donor and recipient sites without the use of skin grafts or other more major procedures. According to the authors, this procedure is a viable alternative in repairing large defects in the anterior chest wall.     

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.     

Skin-sparing mastectomy and immediate autologous tissue reconstruction after whole-breast irradiation

Traditional breast conservation therapy consists of lumpectomy and whole-breast irradiation. Local recurrence after breast conservation is usually managed with salvage mastectomy. Skin-sparing mastectomy and immediate autologous tissue reconstruction is an accepted method of managing primary breast malignancies with exceptional aesthetic results. The purpose of this study was to evaluate this technique in the previously irradiated breast. This study is a retrospective review of all patients undergoing skin-sparing mastectomy and immediate reconstruction with autologous tissue after failed breast conservation therapy between 1995 and 1999. There were 11 patients with a mean age of 45 years (range, 34 to 58 years). Initial lumpectomy was performed for ductal carcinoma in situ in six patients and infiltrating carcinoma (ductal or lobular) in five patients. The interval from lumpectomy to salvage mastectomy ranged from 12 to 169 months (mean, 44 months). Reconstructive techniques included unipedicled transverse rectus abdominis musculocutaneous (TRAM) flap (n = 4), free TRAM flap (n = 4), and latissimus flap with immediate placement of a saline implant (n = 3). Flap survival was 100 percent, and there were no early flap complications. One patient developed partial-thickness mastectomy flap loss (3 x 3 cm), which was managed conservatively. There were no instances of full-thickness mastectomy skin loss. Late complications included capsular contracture (n = 2), fat necrosis (n = 1), and ventral hernia (n = 1). There was one late death from metastatic disease; the remaining patients were without evidence of disease at a mean of 48 months (range, 30 to 75 months). Aesthetic results were judged as excellent (n = 4), good (n = 5), fair (n = 1), and poor (n = 1). These results demonstrate that skin-sparing mastectomy and immediate autologous tissue reconstruction can be safely performed in patients with previous whole-breast irradiation. Clearly, patient selection is paramount with attention to the quality of the irradiated breast skin and the anatomic location of the recurrent disease. In this experience, the best results were seen after TRAM (pedicled or free) flap reconstruction.     

Breast cancer after augmentation mammaplasty: treatment by skin-sparing mastectomy and immediate reconstruction

Breast conservation has been associated with poor cosmetic outcome when used to treat breast cancer in patients who have undergone prior augmentation mammaplasty. Radiation therapy of the augmented breast can increase breast fibrosis and capsular contraction. Skin-sparing mastectomy and immediate reconstruction are examined as an alternative treatment.Six patients with prior breast augmentation were treated for breast cancer by skin-sparing mastectomy and immediate reconstruction. One patient underwent a contralateral prophylactic skin-sparing mastectomy. Silicone gel implants had been placed in the submuscular location in five patients and in the subglandular position in one patient a mean of 10.2 years (range, 6 to 20 years) before breast cancer diagnosis. The mean patient age was 41.3 years (range, 33 to 56 years). Four independent judges reviewed postoperative photographs to grade the aesthetic results in comparison with the opposite native or reconstructed breast.The American Joint Committee on Cancer staging was stage 0 in one patient, stage I for four patients, and stage II for one patient. Five of the six patients presented with a palpable breast mass. Latissimus dorsi flap reconstruction was performed in four patients (bilaterally in one) and a transverse rectus abdominis muscle (TRAM) flap was used in two patients. Three patients were treated by skin-sparing mastectomy with preservation of the breast implant (two patients with latissimus flaps, and one patient with a TRAM flap). The tumor location necessitated the removal of implants in two patients (one patient with a latissimus flap and one with a TRAM. A saline implant was placed under the latissimus flap after gel implant removal. The patient who underwent bilateral skin-sparing mastectomies desired explantation and placement of saline implants. No remedial surgery was performed on the opposite breast to achieve symmetry. Complications occurred in two patients at the latissimus dorsi donor site (seroma in one patient, and seroma and infection in one). Five patients underwent complete nipple reconstructions. The mean duration of follow-up was 33.6 months (range, 15.5 to 70.3 months), and there were no recurrences of breast cancer. The aesthetic results were judged to be good to excellent in all cases.Skin-sparing mastectomy and immediate reconstruction can be used in patients with prior breast augmentation, with good to excellent cosmetic results. Depending on the tumor and implant location, the implant may be preserved without compromising local control.     

The inferior gluteal free flap in breast reconstruction

The inferior gluteal musculocutaneous free flap usually provides a sufficient amount of autogenous tissue for breast reconstruction when adequate tissue is not present in the lower abdomen or back. Its arteriovenous pedicle is longer than the superior gluteal musculocutaneous free-flap pedicle and permits microvascular anastomosis in the axilla, avoiding medial rib and cartilage resection. In the thin patient, there is more available donor tissue than with the superior gluteal musculocutaneous free flap. Cadaver dissections confirm the greater pedicle length and the local area of the lower gluteus maximus muscle needed to carry the skin island and have helped define a safe approach to flap elevation. We have used four flaps for breast reconstruction without vascular compromise or the need for reexploration. The low donor-site scar in the inferior buttock fold has been acceptable, especially for a bilateral reconstruction. The anatomy of the gluteal region, the surgical technique for the inferior gluteal free-flap transfer, and a 3-year patient follow-up are presented.     

The transverse myocutaneous gracilis free flap: a valuable tissue source in autologous breast reconstruction

The transverse myocutaneous gracilis free flap with a transverse orientation of the skin paddle in the proximal third of the medial thigh region allows the taking, in selected patients, of a moderate amount of tissue for autologous breast reconstruction. The donor-site morbidity is similar to that of a classic medial thigh lift. The indication for this flap in autologous breast reconstruction and the surgical technique will be discussed in this article. From August of 2002 to March of 2003, 10 patients underwent autologous breast reconstruction with 12 transverse myocutaneous gracilis free flaps. The patients' ages ranged from 26 to 48 years (median, 40 years). Of those, two BRCA-positive women received bilateral breast reconstructions after prophylactic skin-sparing mastectomy, and eight patients received immediate breast reconstruction after skin-sparing mastectomy in early-stage breast cancer. Mean follow-up of the 10 patients was 5 months (range, 1 to 9 months). We had no free-flap failure. Four patients had small areas of ischemic skin necrosis related to very thin preparation of the skin envelope after skin-sparing mastectomy without altering the final aesthetic results. Cosmetic evaluation of the reconstructed breasts and thigh donor site by two plastic surgeons showed good results in nine patients and fair results in one patient. There was no functional donor-site morbidity caused by harvesting the gracilis flap. The transverse myocutaneous gracilis flap is a valuable alternative for immediate autologous breast reconstruction after skin-sparing mastectomy in patients with small and medium-sized breasts and inadequate soft-tissue bulk at the lower abdomen and gluteal region.     

Breast cancer recurrence after immediate reconstruction: patterns and significance

Local recurrence of cancer after mastectomy and immediate breast reconstruction is generally regarded as a poor prognostic indicator. This study was conducted to identify specific patterns of local recurrence following reconstruction and to determine their biological significance. The records of all patients who had undergone immediate breast reconstruction at The University of Texas M. D. Anderson Cancer Center between June 1, 1988, and December 31, 1998, were reviewed. The records of patients who had local tumor recurrence were then carefully analyzed. During this 10-year period, a local recurrence of cancer was found to have developed in 39 of 1694 patients (2.3 percent). Most recurrences were in the skin or subcutaneous tissue (n = 28; 72 percent), and the remainder were in the "chest wall" (n = 11; 28 percent), as defined by skeletal or muscular involvement. Transverse rectus abdominis myocutaneous flaps were used most often in both groups, but latissimus dorsi myocutaneous flaps and implant techniques were also used in some patients. Patients with subcutaneous tissue recurrence had an overall survival rate of 61 percent at follow-up of 80.8 months, compared with patients with chest wall recurrence, whose survival rate was 45 percent at similar follow-up. Metastases were less likely to develop in patients with subcutaneous tissue recurrence than in those with chest wall recurrence (57 percent versus 91 percent; p = 0.044); the former group also had a greater chance of remaining disease-free after treatment of the recurrence (39 percent versus 9 percent), respectively. Metastasis-free survival was higher in patients with subcutaneous tissue recurrence than with chest wall recurrence (2-year and 5-year survival: 52 and 42 percent versus 24 and 24 percent; p = 0.04). In both groups, the time to detection of the recurrence was similar (subcutaneous tissue recurrence, 27.1 months, versus chest wall recurrence, 29.5 months). Distant disease did not develop in one patient only in the chest wall recurrence group; this patient remained disease-free at 70 months. From these results, it was concluded that (1) not all local recurrences are the same: patients with subcutaneous tissue recurrence have better survival rates, a decreased incidence of metastases, and a greater chance of remaining disease-free than do those with chest wall recurrence; (2) immediate breast reconstruction (although potentially, it can conceal chest wall recurrence) does not seem to delay the detection of chest wall recurrence; and (3) even if a chest wall recurrence develops, it is highly associated with metastatic disease, and the survival rate is not likely to have been influenced by earlier detection. These data support the continued use of immediate breast reconstruction without fear of concealing a recurrence or influencing the oncologic outcome.     

Integrated breast mound reduction and nipple reconstruction with the wraparound flap.

A new method for nipple reconstruction is described that combines revision of an autologous tissue breast mound with creation of a projecting nipple. The method is applicable only to reconstructed breast mounds that must be reduced or lifted to achieve symmetry with the opposite breast. In this technique, the mound is reduced as if it were a normal breast, using an inverted-T or vertical mammaplasty pattern. In this way, breast projection can be increased and, if necessary, the inframammary fold can be elevated. A rectangular flap is created from skin and subcutaneous tissue that would normally be discarded during the breast reduction, and this flap is wrapped around on itself to form a projecting nipple. This new technique avoids the flattening of the breast mound usually seen after nipple reconstruction because it does not take tissue away from the completed breast mound to make the nipple. In appropriate patients who require reduction in size of their reconstructed breast mound, the wraparound flap nipple reconstruction is worth considering.     

Treatment of difficult TRAM flap hernias using intraperitoneal synthetic mesh application

The authors report the successful repair of large lower abdominal hernia defects after transverse rectus abdominis muscle (TRAM) flap breast reconstruction in 11 patients using a technique of intraperitoneal application of synthetic polypropylene (Prolene) mesh anchored to the peritoneal surface of the abdominal wall tissues. Five of these patients had previously failed hernia repairs after a unipedicle TRAM flap breast reconstruction employing the onlay mesh technique, with two of the patients having undergone three previous hernia repairs. The other six patients had developed large hernias after bipedicle TRAM flap reconstruction without previous mesh supplementation of the abdominal wall repair. After their successful hernia repairs, all of the patients healed without difficulty and demonstrated no sign of recurrence in an 8 to 36-month follow-up. Each patient returned to her activity level before breast reconstruction.     

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.     

Total ear reconstruction in the devascularized temporoparietal region: II. Use of the omental free flap

Total ear reconstruction using the omental free flap technique was performed on five patients who presented with a devascularized temporoparietal region. The main indication for this technique was unavailability of the contralateral temporoparietal fascia in those requesting autogenous auricular reconstruction. There were no microvascular failures in the procedures conducted. In one case there was a partial loss of the transferred omentum, which resulted from an inadequate omental tailoring. A normal convoluted auricle was obtained after multistage debulking operations and meticulous postoperative molding. The average follow-up period was 3.4 years. Final aesthetic results were graded as satisfactory in four patients and poor in one patient.     

Breast reconstruction with superficial inferior epigastric artery flaps: a prospective comparison with TRAM and DIEP flaps

Breast reconstruction using the lower abdominal free superficial inferior epigastric artery (SIEA) flap has the potential to virtually eliminate abdominal donor-site morbidity because the rectus abdominis fascia and muscle are not incised or excised. However, despite its advantages, the free SIEA flap for breast reconstruction is rarely used. A prospective study was conducted of the reliability and outcomes of the use of SIEA flaps for breast reconstruction compared with transverse rectus abdominis musculocutaneous (TRAM) and deep inferior epigastric perforator (DIEP) flaps. Breast reconstruction with an SIEA flap was attempted in 47 consecutive free autologous tissue breast reconstructions between August of 2001 and November of 2002. The average patient age was 49 years, and the average body mass index was 27 kg/m. The SIEA flap was used in 14 (30 percent) of these breast reconstructions in 12 patients. An SIEA flap was not used in the remaining 33 cases because the SIEA was absent or was deemed too small. The mean superficial inferior epigastric vessel pedicle length was approximately 7 cm. The internal mammary vessels were used as recipients in all SIEA flap cases so that the flap could be positioned sufficiently medially on the chest wall. The average hospital stay was significantly shorter for patients who underwent unilateral breast reconstruction with SIEA flaps than it was for those who underwent reconstruction with TRAM or DIEP flaps. Of the 47 free flaps, one SIEA flap was lost because of arterial thrombosis. Medium-size and large breasts were reconstructed with hemi-lower abdominal SIEA flaps, with aesthetic results similar to those obtained with TRAM and DIEP flaps. The free SIEA flap is an attractive option for autologous tissue breast reconstruction. Harvest of this flap does not injure the anterior rectus fascia or underlying rectus abdominis muscle. This can potentially eliminate abdominal donor-site complications such as bulge and hernia formation, and decrease weakness, discomfort, and hospital stay compared with TRAM and DIEP flaps. The disadvantages of an SIEA flap are a smaller pedicle diameter and shorter pedicle length than TRAM and DIEP flaps and the absence or inadequacy of an arterial pedicle in most patients. Nevertheless, in selected patients, the SIEA flap offers advantages over the TRAM and DIEP flaps for breast reconstruction.     

The deep inferior epigastric perforator flap for breast reconstruction in overweight and obese patients

The authors retrospectively reviewed the computerized records of 71 women undergoing 80 deep inferior epigastric perforator (DIEP) flap reconstructions after mastectomy over a 1-year period. There were 33 normal, 26 overweight, and 12 obese patients. No statistically significant difference in flap complications was found between groups. Overall fat necrosis rates were 11.4 percent for the normal-weight patients, 6.7 percent for the overweight patients, and 6.7 percent for the obese patients. Postoperative hospital time was similar for all groups. The occurrence of abdominal wall fascial laxity was uncommon and similar for all groups. Large (>900 g) reconstructions were completed without prohibitive complications in the reconstruction flap. The DIEP flap represents a significant advance in autologous breast tissue reconstruction. Although concerns regarding fat necrosis rates in DIEP flaps have been voiced, the authors did not see an increasing rate of fat necrosis in their overweight and obese patients, and their overall rate of fat necrosis is comparable to rates reported for free transverse rectus abdominis myocutaneous (TRAM) flaps. Also, increasing body mass index did not seem to affect the rate of delayed complications of the abdominal wall, such as abdominal wall hernia or bulging. Although it was not statistically significant, the authors did observe a trend toward increased wound-healing complications with increasing body mass index. Their data also support the claim that the complete sparing of the rectus abdominis muscles afforded by the DIEP flap avoids abdominal wall fascial bulging or defects often seen in obese TRAM reconstruction patients. Because flap and wound complication rates are similar or superior to those of other autologous tissue reconstruction techniques and the occurrence of abdominal wall defects is all but eliminated, the DIEP flap likely represents the preferred autologous breast reconstruction technique for overweight and obese patients.     

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.
