摘　　要：目的：应用口内下颌骨升支垂直截骨倒置及耳前切口去除骨球关节窝成形术治疗颞下颌关节真性强直，评价其重建颞下颌关节的效果。方法：对5例颞下颌关节骨性强直患者切除病变区骨质，形成关节窝，采用口内下领骨升支垂直截骨倒置升支后部构造新的”髁突”，重建颞下颌关节。手术后常规随访，评价其疗效。结果：全部病例术后随访3～24个月，开口度3．1～4．1cm，平均开口度3．6cm，效果满意。结论：应用口内下颌骨升支垂直截骨倒置及耳前切口去除骨球关节窝成形术治疗颞下颌关节真性强直具有多方面优势，减少了并发症的发生，是治疗颞下颌关节真性强直的有效手术治疗方法。Objective.. To cure ankylosis of temporo--mandibular joint by vertical ramus osteotomy inversion and plastic operation of exorcizing bone--ball acetabulum through preaurieular incision, then evaluate its effect of recon- structing temporomandibular joint. Methods： Five patients with ankylosis of temporo--mandibular joint undergoing the surgery were followed up. Results： In all cases, interincisal distance approached the normal level. No recurrence and TMJ symptom were found during the follow--up. Conclusion： Vertical ramus osteotomy inversion and plastic operation of exorcizing bone--ball acetabulum through preauricular incision can be taken as effective approach to treat ankylosis of temporo--mandibular joint.
