Traumatic unilateral temporomandibular joint dislocation overlooked for more than two decades.
Forward dislocation of the temporomandibular joint commonly can be easily diagnosed and successfully reduced by manual repositioning. In this report, we discuss a rare case of prolonged temporomandibular dislocation that had persisted for more than 20 years because the otolaryngologist and dentist had missed the dislocation. This patient underwent open reduction and mandibular joint plasty with preoperative orthodontic therapy. It is possible that strong pain and mouth-closing disability may gradually remit and only deviated mandibular prognathism like malocclusion may persist. Therefore, abnormal occlusion warrants careful attention to temporomandibular joint dislocation.
