The potential role of disc repositioning in preventing postsurgical recurrence of traumatogenic temporomandibular joint (TMJ) ankylosis was investigated. Seventeen cases of traumatogenic TMJ ankylosis underwent disc repositioning during arthroplasty. During surgery, the dislocated disc was carefully dissected outside the ankylotic TMJ and repositioned over the top of the condylar stump, and then sutured to the soft tissue of the zygomatic root. In the 22 ankylotic TMJs of the 17 patients, dislocated discs were found in front of the ankylotic TMJ, behind the ankylotic TMJ or between the ramus and fossa. At the last follow-up (longer than 1 year) examination, interincisal opening distances ranged from 24 to 43 mm (mean 32.86 mm). No recurrence and TMJ symptoms were found during the period of follow-up. Disc repositioning in the treatment of traumatogenic TMJ ankylosis proves to be a feasible and effective method of preventing recurrence of this condition.
研究了盘复位在预防创伤性颞下颌关节（TMJ）强直术后复发中的潜在作用。17例创伤性TMJ强直患者在关节成形术中进行了盘复位。手术过程中，将脱位的盘在强直的TMJ外仔细解剖，重新置于髁突残端上方，然后缝合至颧根软组织。在17例患者的22个强直TMJ中，发现脱位的盘位于强直TMJ前方、强直TMJ后方或下颌支与关节窝之间。在最后一次随访（超过1年）检查时，切牙间开口距离为24至43mm（平均32.86mm）。随访期间未发现复发及TMJ症状。盘复位治疗创伤性TMJ强直被证明是预防该疾病复发的一种可行且有效的方法。
