To describe the treatment of 2 long-standing chronic dislocation of the temporomandibular joints (TMJs) and 1 chronic recurrent dislocation.
This report describes the treatment of 3 patients; 2 with a long-standing chronic dislocation of the TMJ and 1 with a chronic recurrent dislocation. Duration of dislocation and anatomical considerations make the treatment challenging and controversial. The patients presented in this report all developed destruction of their condyles. They were successfully treated with total joint replacement with alloplastic devices.
All the 3 patients underwent successful surgery and recovery. Mandibular function and pain level were significantly improved.
Long-standing dislocation of the TMJ is rare. This condition can be successfully treated by resection of the damaged condyles and reconstruction with alloplastic total TMJ replacements.
描述颞下颌关节（TMJ）2例长期慢性脱位及1例慢性复发性脱位的治疗情况。
本报告描述了3例患者的治疗情况；2例为TMJ长期慢性脱位，1例为慢性复发性脱位。脱位的持续时间和解剖学因素使得治疗具有挑战性且存在争议。本报告中的患者均出现了髁突破坏。他们通过使用异体装置进行全关节置换成功得到治疗。
所有3例患者手术均成功且康复。下颌功能和疼痛程度显著改善。
TMJ长期脱位罕见。这种情况可通过切除受损髁突并用异体全TMJ置换进行重建而成功治疗。
