Abstract

Eminectomy which is one of the popular and most effective treatments for habitual temporomandibular joint luxation was first described by Myrhaug in 1951. There are few reports which described eminectomy being performed under local anesthesia and conscious sedation. We present a case series of habitual luxation of the TMJ treated by eminectomy performed under local anesthesia and conscious sedation and general anesthesia. Five patients were examined and found to have recurrent luxation of the TMJ. The age of patients ranged from 18 to 93 years. Bilateral eminectomy of the TMJ was performed for two patients, and unilateral eminectomy was performed for three patients. Two were examined under intravenous propofol sedation and local anesthesia, while three patients were examined under general anesthesia. One patient died from ileus one month after surgery. The follow-up period except for the case that died from ileus ranged from 12 to 33 months. No recurrent dislocation of the TMJ has been identified. Based on our experience and two other series in the literature, eminectomy with sedation and local anesthesia can be considered and might be a good option in elderly patients.
