Surgical treatment for recurrent dislocation of the temporomandibular joint with mental disorder or cerebral lesion was carried out in 3 cases. A preauricular incision like a hockey stick which ended in the hair bearing part of the temple was made. In 19-and 22-year old females, a mandibular chip at the sugittal splitting osteotomy for mandibular prognathism and iliac bone were transplanted into the base of zygomatic process of the temporal bone, respectively. On the other hand, in a 73-year old woman, a fragment of the zygomatic arch was pushed out and down toward the articular tubercle by Dautray's technique. Above the two bone grafts and a fragment were fixed by means of intraosseous ligation to the zygomatic arch. There was no recurrent dislocation during a period of 6 to 26 months after surgery.
