Orofacial and mandibular reconstruction with the iliac crest free flap: a review of 60 cases and a new method of classification.
Sixty vascularized iliac crest free-tissue transfers were used for oromandibular reconstruction, 46 as osteocutaneous and 14 as osseous flaps. Forty-one patients had preoperative radiotherapy, and 8 had failed previous attempts at reconstruction. Forty-nine of the 60 reconstructions were carried out primarily, most commonly following ablative surgery for radiorecurrent squamous carcinoma. Ages ranged from 19 to 85 years, and follow-up ranged from 2 months to 5 years. Flap survival was 95 percent. Eight-six percent of patients returned to their previous activities. There were 2 perioperative deaths, and 31 patients were alive at follow-up. Horizontal defects from 5 to 16 cm were reconstructed, and in 22 patients, both oral lining and skin coverage were replaced. Radiographic evidence of bone union was noted in 96 percent of synostoses, and clinical union was seen in all but one patient. One patient required bilateral hemimandibular reconstructions for sequential primaries at different operative sittings. Functional and cosmetic results were generally satisfactory and were excellent in bone-only reconstructions. Several surgical principles evolved to minimize bulk and eliminate the need for intermaxillary fixation or external fixation postoperatively. To improve results in large or more lateral through-and-through defects, an accessory pectoralis musculocutaneous flap proved advantageous. Cosmetic and functional results depend largely on three factors: the extent of the surgery, the leanness of the patient, and his or her position on the surgical learning curve.
