Abstract
Three cases of long-standing bilateral dislocation of the temporomandibular joint in patients with cerebral infarction are presented. The frequency of temporomandibular dislocation has been reported to be higher in patients with psychological and cerebral diseases. In this report, all patients successfully underwent articular eminectomy according to Myrhaug’s method, with the purpose of repositioning the condyles and preventing re-dislocation. Articular eminectomy increased the ease of reduction and was effective in preventing future dislocation of the temporomandibular joint in these patients.
