Abstract
Fifteen patients underwent surgery for retromandibular parotid, pharyngeal, or posterior tongue tumors. Surgical approach to the pterygomaxillary fossa, parapharyngeal space, and posterior tongue was performed by external cervical incision and lateral stair-step mandibulotomy. After resection of the tumors, the mandibular segments were replaced and secured with miniplates. The plates were removed after six weeks whenever postoperative radiation therapy was planned. By reflecting the ascending ramus, this method provides excellent exposure of the concerned areas. It makes unnecessary both incision of the lower lip and intermaxillary fixation with arch bars, thus allowing a quick resumption of oral feeding. A review of 15 patients demonstrated satisfactory results for mandibular function and morphologic appearance, with minimal complications.
