Ankylosis of the temporomandibular joint. Follow-up of thirteen patients.

We undertook a postoperative clinical study of 13 patients with ankylosis of the temporomandibular joints. The study consisted of an evaluation of the surgical concepts of resection and subsequent surgical reconstruction by osteotomy in previous height of the joint space and lining of the glenoid fossa with lyophilized dura. Early mobilization and aggressive physiotherapy are mandatory postoperative measures. According to the theory of mandibular growth as a result of functional matrix, early surgical intervention to correct ankylosis should be performed, regardless of the age of the patient, to prevent recurrence and later asymmetry or distoclusion.
