Perforator-preserving chondrocutaneous rotation flap reconstruction of auricular defects

A technique of chondrocutaneous flap reconstruction of the ear that preserves the perforating branches of the posterior auricular artery is described. Preservation of the perforators offers improved safety in high-risk patients because it maintains the blood supply to the anterior surface of the ear. This perforator-preserving technique also emphasizes simplicity of flap design, concealment of scars, and preservation of ear shape. It is best suited for reconstructing defects of the scapha, antihelix, or triangular fossa up to approximately 2 cm in diameter. A variety of chondrocutaneous rotation flaps have been developed for reconstructing helical and nonhelical defects. These flaps have been designed on the basis of the size and location of the surgical defect. Although previously described techniques are usually reliable, extensive dissection and mobilization can injure perforators, leading to vascular compromise. When flap reconstruction is used in high-risk patients, it is necessary to protect the blood supply, and perforator-preserving flap reconstruction offers improved safety. The perforator-preserving technique was used in six consecutive high-risk patients during a 2-year period. Good results were obtained in all cases, including in patients who smoked cigarettes or had extensive medical problems.     

Reconstruction of proximal nasal defects with island composite nasal flaps

There are few local nasal flap options for repair of proximal nasal defects. Absence of suitable donor sites and the large dimensions of the defects limit the use of local nasal flaps in this region. Regional paranasal flaps may not be suitable in these cases because of color, texture, and donor-site scars. The composite procerus muscle and nasal skin flap, which is vascularized by the dorsal nasal branch of the angular artery, can be a useful treatment modality for proximal nasal reconstruction. Seven patients were successfully treated using the composite nasal flaps. The maximal size of the defects was 2.4 cm. In one case, the composite nasal flap was readvanced to close a new defect resulting from reexcision. The composite nasal flap has several advantages in reconstruction of proximal nasal defects. Reconstruction is performed with the same tissue and the donor defect is closed primarily. The composite nasal flap can be moved in multiple directions and has great mobility to reach every point of the proximal part of the nose with axial blood supply. Furthermore, it can be easily readvanced without additional morbidity in case of reexcision.     

The medial adiposofascial flap of the leg: anatomical basis and clinical applications

Despite recent advances in microsurgical techniques, coverage of lower leg defects by locoregional flaps remains indicated in selected cases. The interest in these types of flaps has improved because recent clinical work advocates that fascial and fasciocutaneous flaps can be well indicated for bone coverage. The anatomical study of the medial adiposofascial flap is presented in this article. The flap is based on the rich vascular network supplied by the saphenous artery and the posterior tibial artery perforators. This flap can be harvested on the anteromedial aspect of the leg and can be mobilized to cover defects located between the patella and the heel. This multiple blood supply makes it possible to harvest this flap in various ways, so various defects can be covered. To confirm and prove the versatility and clinical value of this flap, the authors have studied a series of 22 cases in which this flap was used for coverage of lower leg defects. For these defects, especially when situated in the lower third or around the heel and ankle, coverage by a free flap is most often the only proposed solution. However, the authors have obtained excellent results in the majority of these cases, avoiding a free flap procedure. Moreover, in this way, the option of using a free flap remains possible if needed. There is minimal donor-site morbidity and a high functional and aesthetic outcome, making this flap a first-choice flap in selected cases of lower leg defects.     

Use of the free dorsalis pedis flap in head and neck repairs.

Many defects of the head and neck can be readily repaired with a free dorsalis pedis flap, and we report success with these flaps in 9 of 12 cases. A precise knowledge of the anatomy of the arterial supply of the flap is necessary. Preoperative arteriography is recommended if the dorsalis pedis artery is not easily palpable, or if an anomalous distribution of the artery along the dorsum of the foot is sus pected. However, the transfer of the flap should be delayed for two weeks after preoperative arteriography is performed. The one-stage soft tissue reconstruction with a free dorsalis pedis flap has been associated with minimal morbidity and good acceptance by patients. A delay procedure for the flap seems to enhance the chances of complete survival which is so necessary in the repair of intraoral and pharyngeal defects. Careful attention to details and close monitoring of the flap will minimize morbidity. In case of an early failure of a flap, a secondary reconstruction by a different flap can be done in the first 48 to 72 hours. Early postoperative radiotherapy has been well tolerated over these free flaps.     

A Comparative Study of Four Types of Free Flaps from the Ipsilateral Extremity for Finger Reconstruction

Aim

To compare the outcomes of finger reconstruction using arterialized venous flap (AVF), superficial palmar branch of the radial artery (SPBRA) flap, posterior interosseous perforator flap (PIPF), and ulnar artery perforator free (UAPF) flap harvested from the ipsilateral extremity.

Methods

We retrospectively reviewed the outcomes for 41 free flaps from the ipsilateral extremity in the reconstruction of finger defects in 41 patients with small/moderate skin defects, including 11 AVFs, 10 SPBRA flaps, 10 PIPFs, and 10 UAPF flaps. Standardized assessment of outcomes was performed, including duration of operation, objective sensory recovery, cold intolerance, time of returning to work, active total range of motion (ROM) of the injured fingers, and the cosmetic appearance of the donor/recipient sites.

Results

All flaps survived completely, and the follow-up duration was 13.5 months. The mean duration of the complete surgical procedure for AVFs was distinctly shorter than that of the other flaps (p<0.05). AVFs were employed to reconstruct skin defects and extensor tendon defects using a vascularized palmaris longus graft in 4 fingers. Digital blood supply was reestablished in 4 fingers by flow-through technique when using AVFs. Optimal sensory recovery was better with AVFs and SPBRA flaps as compared with UAPF flaps and PIPFs (p<0.05). No significant differences were noted in ROM or cold intolerance between the 4 groups. Optimal cosmetic satisfaction was noted for the recipient sites of AVFs and the donor sites of SPBRA flaps. The number of second-stage defatting operations required for AVFs was considerably lesser than that for the other flaps.

Conclusion

All 4 types of free flaps from the ipsilateral extremity are a practical choice in finger reconstruction for small/moderate-sized skin defects. AVFs play an important role in such operations due to the wider indications, and better sensory recovery and cosmetic appearance associated with this method.     

The reverse auricular flap: a new flap for nose reconstruction.

In the present article, the authors describe a new chondrocutaneous island flap from the ear helix for nose reconstruction. Anatomic studies showed that helix vascularization depends mainly on the superficial temporal vessels. The presence of vascular communications between the anterior frontal branch of the superficial temporal system and the supraorbital and supratrochlear arterial systems allows this flap to be used in a reverse vascular flow fashion. This new flap has been used successfully in seven cases for reconstructing composite defects of the nasal tip and ala. The donor-site defect is repaired with an advancement and rotation flap from the helical rim, leaving an inconspicuous scar and giving an acceptable cosmetic result of the donor area.     

The role of microsurgery in reconstruction of oncologic chest wall defects.

Regional pedicled myocutaneous flaps are usually the best choice for soft-tissue coverage of full-thickness chest wall defects. As defects increase in size, microsurgical techniques are necessary to augment blood flow to pedicled flaps or to provide free flap coverage from distant sites. This study retrospectively reviews all microsurgical procedures performed at one institution for the coverage of full-thickness chest wall defects. Twenty-five cases of full-thickness chest wall reconstruction are reviewed. There were 20 free flaps and five supercharged pedicled flaps. A rectus abdominis myocutaneous flap (free or supercharged) was used in 20 cases, and a filet free flap following forequarter amputation was used in five patients. Large skeletal defects were repaired with a Marlex mesh/methylmethacrylate sandwich prosthesis. There was 100 percent flap survival and one case of minor, partial flap loss. The prosthesis remained effectively covered in all cases. Five patients required ventilatory support for up to 10 days postoperatively. There were three perioperative deaths due to multisystem failure. Microsurgical techniques are extremely useful for reconstruction of complicated, composite chest wall defects. They are indicated when regional pedicled flap options are unavailable or inadequate. These flaps have a 100 percent success rate and uniformly result in stable soft-tissue coverage.     

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.     

The "reduced" latissimus dorsi musculocutaneous flap

This report introduces a new device among latissimus dorsi flaps: the "reduced" latissimus dorsi musculocutaneous flap. This flap consists of a proximal musculocutaneous unit and a distal, thin fasciocutaneous unit (the "reduced" portion). The former unit carries a reliable blood supply from the thoracodorsal artery and is able to cover deeper recipient defects, while the latter provides a well-contoured reconstruction of the defect. If needed, an extended portion and/or a thin cutaneous flap can be carried along with the flap according to the defect. In our clinic, we have so far used four pedicled and one free reduced latissimus dorsi musculocutaneous flap in the repair of a variety of defects. All flaps survived, and satisfactory contour of the recipient site was achieved in each case. These clinical experiences clarify that a reduced portion 10 cm in length can be safely carried, and it is suggested that survival of this flap does not depend on its width-to-length ratio.     

Anterolateral thigh flap for abdominal wall reconstruction

The free or pedicled anterolateral thigh flap was introduced for the reconstruction of large abdominal wall defects. This flap is superior to the tensor fasciae latae musculocutaneous flap in several respects. These include the wide, reliable skin territory (which can reach the level of the knee) and the long pedicle. Therefore, a pedicled anterolateral thigh flap with reliable blood circulation can easily be positioned above the umbilicus. In addition, the free anterolateral thigh flap has greater freedom of orientation and can be used to repair larger abdominal wall defects than can the tensor fasciae latae flap. Seven patients in whom abdominal wall defects had been reconstructed with pedicled or free anterolateral thigh flaps were reviewed. Their average age was 47.1 years (range, 21 to 74 years), and the average follow-up period was 10.7 months (range, 2 to 21 months). The size of the abdominal wall defects ranged from 12 x 12 cm to 18 x 24 cm, and the size of the transferred flap ranged from 10 x 20 cm to 20 x 20 cm. Three flaps were pedicled and four were free, of which three incorporated the tensor fasciae latae flap. All flaps survived completely, and no postoperative abdominal hernias developed. Despite some variations in vascular anatomy and technical difficulties in elevating the anterolateral thigh flap, the authors conclude that the pedicled or free anterolateral thigh flap is superior to the tensor fasciae latae flap for reconstruction of large abdominal wall defects.     

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.     

Versatility of the medial plantar flap: our clinical experience

The medial plantar flap presents an ideal tissue reserve, particularly for the reconstruction of the plantar and palmar areas, which require a sensate and unique form of skin. In the past 5 years, the authors performed 16 free flaps, 10 locally pedicled flaps, and five cross-leg flaps on 31 patients for the reconstruction of palmar and plantar defects. All flaps transferred to the palmar area survived, providing good color match and sufficient bulkiness. The overall results were satisfactory in terms of function and sensation, and no complications related to flap survival in the plantar area were observed. All flaps used to cover defects in the heel and ankle region adapted well to their recipient areas, and all lower extremities remained functional. Because the medial plantar flap presents glabrous, sensate skin with proper bulkiness and permits the movement of underlying structures, the authors advocate its use and view this procedure as an excellent alternative in the reconstruction of palmar and plantar weight-bearing areas.     

Reconstruction of large sacral defects following total sacrectomy

Total sacrectomies for cancer ablation often result in extensive defects that are challenging to reconstruct. In an effort to elucidate the criteria to select the most effective reconstructive options, we reviewed our experience with the management of large sacral wound defects. All patients who had a sacral defect reconstruction after a total sacrectomy at our institution between January of 1993 and August of 1998 were reviewed. The size of the defect, the type of reconstruction, postoperative complications, and functional outcome in each patient were assessed. A total of 27 flaps were performed in 25 patients for sacral defect reconstruction after a total sacrectomy. Diagnoses consisted of chordoma (n = 13), giant cell carcinoma (n = 2), sarcoma (n = 5), rectal adenocarcinoma (n = 4), and radiation induced necrosis (n = 1). The size of sacral defects ranged from 18 to 450 cm2 (mean, 189.8 cm2). Ten patients, including five who had preoperative radiation therapy, underwent transpelvic vertical rectus abdominis myocutaneous (VRAM) flap reconstruction for sacral defects with a mean size of 203.3 cm2. Of these, five patients (50 percent) had complications (four minor wound dehiscences and one seroma). Eight patients, including one who had preoperative radiation therapy, underwent bilateral gluteal advancement flap reconstruction for sacral defects with a mean size of 198.0 cm2. They had no complications. Two patients, both of whom had preoperative radiation therapy, underwent gluteal rotation flap reconstruction for sacral defects of 120 cm2 and 144 cm2. Both patients had complications (one partial flap loss and one nonhealing wound requiring a free flap). Three patients, including one who had preoperative radiation therapy, underwent reconstruction with combined gluteal and posterior thigh flaps for sacral defects with a mean size of 246 cm2; two of these patients had partial necrosis of the posterior thigh flaps. Three patients, all of whom had preoperative radiation therapy, underwent free flap reconstruction for sacral defects with a mean size of 144.3 cm2. They had no complications. Our experience suggests that there are three reliable options for the reconstruction of large sacral wound defects: bilateral gluteal advancement flaps, transpelvic rectus myocutaneous flaps, and free flaps. In patients with no preoperative radiation therapy and intact gluteal vessels, the use of bilateral gluteal advancement flaps should be considered. In patients with a history of radiation to the sacral area and in patients whose gluteal vessels have been damaged, the use of the transpelvic VRAM flap should be considered. If the transpelvic VRAM flap cannot be used because of previous abdominal surgery, a free flap should be considered as a last option.     

Deepithelialized turnover flaps in burns

Acute and chronic burns leave behind a full-thickness defect that always requires a flap cover. Such defects are common in electrical burn injuries of the limbs. This paper deals with 35 patients with full-thickness defects following burns in whom deepithelialized turnover dermis flaps and deepithelialized turnover flaps with deep fascia have been used. This flap is an extension of Hynes's reversed dermis graft and Smahel's deepithelialized turnover flap where there is a larger area of blood supply on the deeper aspect of the dermis. If a good hinge is provided for safe blood supply, such a flap settles well in the defect, and cumbersome multistaged procedures can be avoided. If there is less fatty tissue in the area of flap used, then reversed dermis flaps are ideal because split-skin graft take is good. When there is a lot of fatty tissue on the undersurface of dermis, the fascia is also included to make it a reversed fasciocutaneous flap to augment the blood supply and for better split-skin graft survival. Advantages of the procedure and complications are elaborated.     

Microsurgical reconstruction in recurrent oral cancer: use of a second free flap in the same patient

Primary microsurgical reconstruction is the treatment of choice for ablative defects of oral carcinoma. As a result of this trend, more and more patients with recurrent oral carcinoma who have been initially treated with surgical excision and reconstructed with free flaps are being seen. However, a second microsurgical reconstruction attempt in these cases raises questions about the flap choices, availability of recipient vessels, and effects of previous treatment modalities. Herein, 35 patients with perioral carcinoma who had two successive tumor resections and reconstruction with free flaps on each occasion are presented. A total of 75 free tissue transfers were carried out for the first and second reconstructions. After the first tumor resection, 28 radial forearm fasciocutaneous flaps, 7 fibula osteoseptocutaneous flaps, 1 iliac osteomyocutaneous flap, and 2 rectus abdominis myocutaneous flaps were used. For reconstruction after the recurrence, 17 radial forearm fasciocutaneous flaps, 13 fibula osteoseptocutaneous flaps, 3 rectus abdominis myocutaneous flaps, 2 anterolateral thigh flaps, 1 jejunum flap, and 1 tensor fasciae latae flap were used. More vascularized bone transfers were performed during the second reconstruction since the excision for the recurrence frequently required segmental mandibulectomy. The complete flap survival rate was 97.3 percent and 94.6 percent with a reexploration rate of 7.9 percent and 13.5 percent for the first and second free tissue transfers, respectively. The mean follow-up time throughout the procedures was 37.5 months. Disease-free interval between reconstructions was 20.8 months. At the time of evaluation, 54.3 percent of the patients were surviving an average of 19 months since the second reconstruction. The results suggest that free flaps represent an important option in reconstruction of recurrent perioral carcinoma cases undergoing reexcision. When used in this indication they are as safe and effective as the initial procedure.     

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.     

Partial and complete reconstruction of Achilles tendon defects with the fasciocutaneous infragluteal free flap

Multiple attempts to repair the Achilles tendon can be associated with major soft-tissue defects of skin and tendon necessitating reconstruction with free flaps. In view of its specific anatomical characteristics, the fasciocutaneous infragluteal free flap is best suited for restoring sensibility and achieving nearly full function, including resumption of sporting activities, with minimum donor-site morbidity. The anatomy, dissection technique, and results of 100 percent successful skin and tendon defect reconstruction in seven patients are presented.     

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.     

Use of an adipofascial flap based on the proximal perforators of the ulnar artery to correct contracture of elbow burn scars: an anatomic and clinical approach.

Different techniques can be used to repair contracture of burn scars on the elbow, including local or distant pedicle flaps, muscle or myocutaneous flaps, free flaps, and tissue expanders. Among these, a pedicled adipofascial flap based on the most proximal two to four perforators of the ulnar artery (located 1 to 5 cm from the origin of the artery) can be anastomosed to form a sort of axially patterned blood supply within the fascia and subcutaneous fat. Therefore, no major vessel in the forearm need ever be severed. In addition, use of this type of flap preserves muscle function. The pedicled adipofascial flap described in this article allows for early rehabilitation because the flap is thin and pliable. Additional advantages are the easy and quick dissection and completion of the procedure in one stage. A detailed anatomic dissection of the flap was performed on 16 upper extremities from fresh cadavers; an injection study was also performed to determine the location and dimensions of the pedicle flap and its area of reach around the elbow. In the past 3 years, 14 flaps were used in 13 patients to repair elbow defects after release of burn scar contractures. Flap dimensions ranged from 4 x 7 cm to 6 x 14 cm (mean flap size, 74 cm). The results were very satisfactory.     

Management of secondary soft-tissue deficits following microsurgical head and neck reconstruction by means of another free flap

Secondary soft-tissue deficits may develop following a microsurgical reconstruction in the head and neck region because of inadequate planning or chronic effects of radiotherapy. Although most cases could be managed with alternative methods, free flaps might be necessary in difficult cases. Herein are described 11 cases of microsurgical head and neck reconstruction in which secondary soft-tissue deficits required transfer of another soft-tissue free flap. All patients had malignant tumors treated with surgical resection, and their defects were reconstructed with free flaps. Seven patients received either preoperative or postoperative adjunctive radiotherapy. These patients gradually developed signs and symptoms of soft-tissue deficiency in the reconstructed area, and a soft-tissue free flap transfer was required for treatment within an average of 21.5 months of their initial reconstruction. Five rectus abdominis, one rectus femoris, one latissimus dorsi, one tensor fasciae latae myocutaneous, one radial forearm, one medial arm, and one dorsalis pedis flap were used for this purpose. All flaps survived completely. The average follow-up time was 32 months. Significant improvement was achieved in all cases, and no further major surgical procedures were required. Secondary soft-tissue deficits that could not be predicted or prevented during the initial microsurgical reconstruction may be treated successfully by a subsequent free soft-tissue transfer in selected cases.
