Abstract
We herein present a case of habitual temporomandibular joint (TMJ) dislocation treated surgically by eminectomy. A 56-years-old female patient with cognitive impairment following cerebral tumor resection presented with bilateral recurrent condylar dislocation. Preoperative 3D-CT revealed that the condyle was located anterior to the eminence and there was no evidence of morphological malformation. We first attempted autologous blood injection however, this was not effective. Therefore, a surgical procedure under general anesthesia was planned. Intra-operative findings revealed that the lateral temporal muscle was atrophied resulting from previous neurosurgical procedure. At 6 months follow-up evaluation, there were no signs of recurrence of habitual TMJ dislocation. In order to obtain favorable or good outcomes for habitual TMJ dislocation, selection of treatment method must be based on the patient's social background, the cause and the patient's condition.
