title: AO/ASIF plate for mandibular reconstruction in tumor surgery: results in 20 cases.
abstract: Between May, 1983, and February, 1987, the authors performed mandibular reconstruction using an AO/ASIF plate in 20 patients. Apart from accurate modelling of the resected segment using a template, the key features of the technique include firm fixation and wrapping the plate with pectoralis major muscle. In 19 cases the plate was inserted at the same operation as the resection of a malignant neoplasm. In 10 cases the anterior mandibular osteotomy was placed on the far side of the midline, while in five the mandible was disarticulated through the temporomandibular joint. Eleven patients are alive (average survival 22 months) and nine have died (average survival 10 months). Two AO/ASIF plates have required removal because of exposure, while in three patients limited plate exposure was corrected with a minor surgical procedure. Seven patients had soft tissue complications that were managed conservatively. Nine of the patients had been irradiated previously. Five patients were fitted with dentures successfully. The authors believe that this technique provides a safe, rapid, functional and esthetically satisfactory method of mandibular reconstruction in the patient undergoing surgery for malignant disease.
