Ameloblastoma of the mandible treated by resection, preservation of the inferior alveolar nerve, and bone grafting.

The results of five cases of ameloblastoma of the mandible treated by resection, preservation of the inferior alveolar nerve, and immediate bone grafting are reported. The incisions in all cases healed by first intention. Lip sensation on the operated side returned to normal in four to six weeks in four cases and slight numbness persisted to the eighth week in one case. All patients were followed postoperatively for 13-15 years. In one case the tumor recurred in the mucous membrane seven years after surgery at the original intraoral site and invaded the underlying bone graft. The indications and contraindications for surgery and details of the procedures, including measures to prevent recurrence, are presented.
