A case of habitual luxation of the temporomandibular joints successfully treated by the Dautrey procedure is presented. The patient (a 21-year-old man) visited our hospital with a complaint of dislocation of his TMJs. Based on cephalometric analysis, the patient was classified as belonging to the long face group. Although he underwent Herrmann's procedure twice, dislocation recurred. Excessive elasticity of the buccal mucosa was considered to be one of the causes of recurrence after Herrmann's operation. Therefore, we performed Dautrey's procedure, which increases the vertical height of the eminence by zygomatic downfracture. Follow-up by three-dimensional CT revealed no reduction of the eminence. There has been no recurrent dislocation during a period of 22 months since surgery. The relation between long face and dislocation is also discussed.
