【摘要】 目的分析颞下颌关节盘钙化的临床特点及影像学表现,以期对该疾病的临床诊断提供帮助。方法分析总结近10年在武汉大学口腔医院接受手术治疗并明确诊断为颞下颌关节盘钙化的患者2例,对患者的临床表现、X线影像及组织病理学资料,结合文献进行回顾性分析。结果患者的临床症状为关节区疼痛、开口受限,患侧后牙开,X线检查可见关节窝内钙化物存在。手术中发现颞下颌关节盘大穿孔,残余的关节盘硬化。病理检查可见大量致密的成熟胶原纤维增生,胶原纤维中可见钙盐沉着;可见软骨细胞增生,大量细胞外基质形成并钙化。结论颞下颌关节盘钙化的诊断需结合临床表现、X线及组织学检查,临床需与颞下颌关节髁突骨瘤、滑膜软骨瘤病等相鉴别。更多还原

【Abstract】 Objective To analysis the clinical and image features of temporomandibular joint(TMJ) disc calcification. Methods The patients diagnosed with TMJ disc calcification treated in School and Hospital of Stomatology, Wuhan University in the latest 10 years were collected, clinical symptom and images of these cases were analyzed, and the published literatures of TMJ disc calcification were reviewed. Results Total 2 cases of TMJ disc calcification with complete clinical data were analyzed. The symptom included mouth opening limitation, TMJ pain, open bite of the affected side molar. Calcified body were found through X-ray examination. Joint disc perforation were found during the surgery.The discs showed calcified features. Collagen hyperplasia, cartilage cells generation and calcification were found in the disc through pathological examination. Conclusion The diagnosis of TMJ disc calcification should be combined the symptom, image features and the surgery, it should be differentiated with TMJ osteoma and synovial membrane chondromasis.更多还原
