A modified approach for eminectomy for temporomandibular joint dislocation under local anaesthesia: report on a series of 50 patients

Conventional eminectomy for habitual dislocation of the temporomandibular joint is usually performed under general anaesthesia. This technique was modified for use under local anaesthesia to treat medically compromised patients. Fifty elderly patients (90 joints) were treated, for whom general anaesthesia was considered a serious risk due to systemic diseases; the dislocation was habitual in 39 and long-standing in 11. Following intravenous sedation and local anaesthesia, a 2-cm superficial vertical skin incision was made directly above the articular eminence.
