摘　　要：目的:探讨喙突增生与颞下颌关节强直的关系,分析喙突增生的机制及其临床意义.方法:对我院1984～2004 年收治的28 例颞下颌关节强直患者进行回顾性分析,观察患者的口腔全景片或CT三维重建,在口腔全景片描记图上测量他们喙突的长度,分析喙突长度与张口度、病史长短的相关性,并随机选106 名颞下颌关节正常的门诊就诊者,对比两者的喙突长度是否有统计学意义.结果:颞下颌关节强直患者与颞下颌关节正常门诊就诊者的喙突长度有显著性差异, 喙突长度与颞下颌关节长期强直有直接的关系.结论:长期颞下颌关节强直会导致喙突增生,相反,单纯喙突增生也会导致颞下颌关节强直.Objectives： To investigate the relationship between coronoid process hyperplasia（CPH） and temporomandibular joint ankylosis （TMJA） and to analyze its pathologic mechanism and clinical meaning. Methods：28 patients with TMJA from 1984 to 2004 were retrospectively studied. The length of coronoid process and the mouth-opening degree were measured on their depicting map of panoramic radiographs. 106 subjects with normal TMJ were enrolled as the controls. The relationship between CPH and case history of TMJA was statistically analysed. Results： Coronoid process in TMJA subjeets was longer than that in the controls（ P 〈0. 05 ）. The coronoid process length in TMJA subjects was correlated with the mouth-opening degree（ r =0. 393 ,P =0. 039） and with the duration of case history（ r = 0. 605,P = 0.01 ）. Conclusions： Long-standing TMJA may lead to coronoid process hyperplasia, coronoid process hyperplasia may result in TMJA.
