Reconstruction of the mandible with vascularized iliac crest flap--initial experience at the Tata Memorial Hospital.

Resection of the mandible for cancer of the oral cavity can result in gross functional and aesthetic deformity. Inspite of technological advances, reconstruction of mandibular defects remains one of the most challenging procedures in head and neck surgery. Conventional methods like alloplastic implants and bone grafting have a high rate of failure. The advent of microvascular techniques for mandibular reconstruction has revolutionised the management of these patients. We present our initial experience based on 18 patients who underwent vascularised iliac creast transfer at the Tata Memorial Hospital between November, 1992 and January, 1994. The operative technique of raising, shaping and fixation of the iliac crest flap as well as advantages and disadvantages are discussed. Postoperative graft viability was assessed using 99mTc-MDP scans during the 1st, 3rd and 12th weeks after surgery. We lost 3 flaps (16.4%) due to uncontrolled infection and vessel thrombosis. All of the remaining patients demonstrated good uptake on bone scans and satisfactory bony union on OPG. We conclude that mandibular reconstruction using the vascularised iliac crest is reliable and produces acceptable postoperative functional results with 88% of patients having no swallowing difficulty, 83% with normal speech and excellent cosmesis in 83% (15/18) of the patients.

Osteomyocutaneous flap reconstruction for major mandibular defects.

Mandibular defects after composite resections for carcinoma of the buccal mucosa require immediate restitution of both form and function with an acceptable cosmetic result. The pectoralis major osteomyocutaneous flap (PM-OMC) provides restoration of bone, soft tissue and skin with minimum morbidity. The procedure is technically simple, and in our series reconstruction using this flap has been performed by consultants, fellows and residents in training. We present a series of 116 PM-OMC flaps with good postoperative mastication in more than 70% of cases, and satisfactory swallowing and intelligible speech in 85% patients.

Reconstruction of chest wall defects following extirpative surgery.

Reconstructive procedures following chest wall resection pose a special surgical challenge. With modern surgical technique, a wide range of reconstructive options are at the surgeon's disposal and, hence it is imperative that the appropriate procedure be selected in a given patient. A total of 64 patients underwent resection of malignant chest wall tumors at the Tata Memorial Hospital. The technique of preference at our institution for reconstruction of full-thickness chest wall defects uses a combination of autogenous fascia lata and Marlex mesh. We present our experience with chest wall reconstruction following extirpative surgery in these patients.

Reconstructive surgery in head and neck cancer.

In the past 15 years dynamic changes have taken place in primary reconstructive procedures for head and neck cancer. We have here described the latest techniques used at the Tata Memorial Hospital in reconstruction of major defects in head and neck cancer surgery.

The folded, bipaddled pectoralis major composite flap in oral cancer reconstruction.

We report on the pectoralis major composite (musculocutaneous or rib osteomusculocutaneous) flap used in bipaddled fashion for one-stage immediate reconstruction in 53 patients with oral cancer. Of these, 44 patients had lesions of buccal mucosa and lateral lower alveolus, and 9 patients had lesions of floor of mouth and middle third of lower alveolus. In one patient this flap was used as a free composite tissue transfer in bipaddled fashion. The flap can be used either before or after radiotherapy in oral cancer and provides both lining mucosa and skin cover. If necessary, a rib (vascularised bone graft) incorporated with this composite flap can give skeletal support for mandibular arch reconstruction.

Surgery for severe trismus in submucous fibrosis.

Bilateral full thickness naso-labial flaps have been used successfully in three patients to give long-term relief of the severe trismus caused by oral submucous fibrosis. The flaps are set into defects created by incision of the oral mucosa. The postoperative rehabilitation compared favourably with other methods and we now advocate the technique for all cases of submucous fibrosis requiring correction of severe trismus.

Folded, bipaddled composite flap in head and neck reconstruction.

A series of 34 patients repaired by folded, bipaddled composite flaps for head and neck cancer surgical defects is presented. Pectoralis major composite flap was used in 33 patients on musculovascular pedicle and 1 patient had a latissimus dorsi composite flap free-tissue transfer. The pectoralis major rib, osteomyocutaneous flap was utilized in 6 patients who had lesions of the mouth floor and anterior mandibular arch. The incorporated rib was used as a vascularized bone graft for the stability of mandibular fragments. Thus, one regional composite flap used in bipaddled fashion enabled the reconstruction of mucosal, skin, and mandibular arch defects.

Primary reconstruction of head and neck cancer with anterior rib, osteomyocutaneous composite flap.

The anterior rib, osteomyocutaneous composite flap (AROCF) incorporating both vessels, supracostal and intercostal, has been harvested for primary reconstruction in advanced head and neck cancer patients. The adequacy of the periosteal circulation alone for the successful free osseous transfer has been well proved. The available length of the internal mammary vessels is sufficient for the successful microvascular anastomosis in the neck. This same AROCF can be used as a pedicled flap based on the pectoralis major musculo-vascular pedicle for successful primary reconstruction in cases in which it is deemed unsuitable for use as a free flap. This is possible because of the unique functional blood supply of the rib.

Folded free radial forearm flap for reconstruction of full-thickness defects of the cheek.

BACKGROUND: Full thickness defects of the cheek have been conventionally reconstructed using the folded forehead flap, cervical flap, pectoralis major myocutaneous flap, or deltopectoral flap in various combinations. We report a modified technique of folding the radial forearm flap for reconstruction of full-thickness defects of the cheek. METHODS: The free radial forearm flap is a type C fasciocutaneous flap based on the radial artery along with its vena commitans and superficial forearm vein. The size and shape of the flap are determined according to the dimensions of the surgical defect. The flap is then lifted off with the fascia of the forearm making it a fasciocutaneous flap, in which the radial artery lies deep to the fascia and gives numerous branches. The flap is disconnected from the donor site only after the recipient vessels have been prepared for anastomosis. Vascular anastomosis is then performed using the operating microscope. This technique was used in 13 patients with carcinoma of the buccal mucosa who underwent fill-thickness excision of the cheek. RESULTS: Flap edema was observed in 4 patients in the immediate post-operative period. Necrosis of the outer paddle was seen in 1 patient. Donor site morbidity was seen in 4 patients who required dressings on an outpatient basis for up to 3 weeks. CONCLUSION: Single-stage reconstruction of full-thickness defects of the cheek with the folded free radial forearm flap is reliable and produces excellent cosmesis with minimal donor site morbidity.
