| 摘 要： | 48例颞下颌关节强直X线片中，发现1例乙状切迹与关节给节粘连形成的关节外骨性强直．为探讨其成因，复查4860份下颌骨X线片，发现1例多个牙先天缺失伴有右乙状切迹中部的畸形骨突，提示乙状切迹处可存在异常骨突并可导致关节外的骨性强直。

| Abstract: | In the radiographs of 48 ankylosis cases, there was one case of bony extra capsular ankylosis caused by bony union of the sigmoid notch and articular eminence. In order to study the reason a retrospective inspection was performed on the mandibular radiographs of 4860 cases. One case with many congenital teeth missing and deformitive bony prominence in the middle region of the sigmoid notch was found. The results suggest that abnormal bony prominence at the sigmoid notch region maybe present and can cause bony extracapsular ankylosis of temporomandibular joint. |
