摘要
颞颌关节紊乱综合征所造成的严重器质病变，常由于关节及其外周软组织的反复遭受急性创伤和慢性劳损所引起的颌肌痉挛、挛缩和功能失衡既对关节结构产生素乱也对骨关节及其外周组织产生由微至重的创伤、破坏和粘连。其主要症状为关节区、颌面部皇自觉痛及压痛和咀嚼食物时关节疼痛，因痛致痉，由痉增痛，互为因果，以至难治。颞颌关节重建及软组织松解术即从全面解决上述问题所采取的一种新疗法，以其因果兼治亦可简称根治术。本文总结１９８６．９－１９９０．１２期间按本文治疗的方法治疗本症２０例的经验，曾作过多次远期随诊，最短１年，最长７年，平均３．６年，未见术前症状复发及后遗症，关节及咀嚼功能恢复均良好。
Abstract The substantial defect of the temporomandi bular joint is usually causedby the internal derangement and neuromuscular disorders of the TMJ.It is alsoasscciated with the erosion of the articular cartilage,the pathological changes of thecondylar head by osteo-arthrtis and the deformity,displacement,and perforation of thearticular disk. The operation is consisted of the following 6 surgical and piosthetic steps,such as :1)to eliminate the neuromuscular disordcrs by detachment and reattachment of the mas-ticatory muscles from the ramus of the mandible,2)to make a cap form osteotomy on thedefective part of the condylar head,3)to make a condyloplasty,4)to reconstruct a newTMJ by use of the original condylar process,5)to repair the perforation of the articulardisk by suturing together the capsular edges,and 6)to make a prosthetic therapy by useof an occlusal plate. From 1988.9 to 1990.11,20 cases have been succesfully performed.In this paperthe details of the operation were described and discussed.
