    Abstract:
    Modern treatment of complex midfacial defects has evolved over the past 5 years, primarily with the advent of reliable vascularized bone flaps and osseointegrated implants. To determine the effectiveness of these advances, 26 consecutive patients with complex midfacial defects treated from 1991 through 1995 with immediate muscle-flap coverage were evaluated. The etiology of the defect included neoplasm (n = 23) and trauma (n = 3). Seventy-eight percent of the patients received adjuvant radiation therapy. Follow-up ranged from 3 months to 4 years, with a mean of 18 months. Twenty-three patients (88 percent) were reconstructed with a single major procedure. All patients had free-flap reconstruction, and 100 percent of the flaps survived. Late tumor recurrence was seen in 5 of 23 patients (22 percent) and was detected promptly. Aesthetic and functional results were rated good or excellent in 77 and 88 percent of the patients, respectively, as determined by patient questionnaires and physical examinations. Fourteen of 18 patients (78 percent) undergoing partial or complete alveolar ridge resection received dental rehabilitation, 43 percent of whom received osseointegrated implants into either a bone flap or remaining native bone. Osseointegrated implants were inset during the initial reconstruction 50 percent of the time. A treatment algorithm for free-flap selection based on the size of the defect and the bony requirement for reconstruction is presented. Bony restoration is only required in those areas where osseointegrated implants need to be placed. In such cases, the fibula osteocutaneous free flap is the flap of choice. Otherwise, soft-tissue flaps are selected based on wound size. Immediate free-flap coverage provides effective, single-stage treatment, both aesthetically and functionally, for complex midfacial defects.
