Ankylosis of the mandible from cancrum oris.

We present 30 cases of ankylosis of the lower jaw following cancrum oris. The clinical and radiological findings, the anesthetic methods, and the surgical management are described. Adequate excision of limiting scar and any bony ankylosis, with immediate mucosal or skin coverage of any raw surfaces created, is the proper approach. Postoperative jaw exercises and the use of a bite block may be helpful.
