Abstract
BACKGROUND: Anterior mandibular osteotomy gives excellent access to the oropharynx for oncologic resections. Although rigid internal fixation has improved results in stability and bone healing, side effects and complications of the surgical procedure must be considered. METHODS: Between 1991 and 1997, 64 patients underwent a transmandibular approach for benign or malignant tumors of the head and neck. Sixty-one of them were included in a 6-month follow-up study. Final results and major and minor complications were recorded. RESULTS: Three (5%) cases of non-union and infection of the osteotomy site required plate removal, curettage, and reosteosynthesis. Occlusal disturbances and local periodontal disease occurred in 2 (3%) patients. Thirty-two (52%) patients complained of sensitivity disturbances, 18 (30%) of temporomandibular joint pain, and 44 (72%) of a limitation in opening the mouth. Six patients (10%) had a cosmetic complaint. CONCLUSION: Dental condition and periodontal care in the vicinity of the osteotomy are important factors in reducing the risk of major complications. Trismus, limitation of joint motion, and pain cannot be directly related to the technique; they depend on the extent of tumor resection and postoperative radiotherapy.
