摘要: 目的: 回顾无明确已知病因的单侧髁突发育不良样改变病例,探讨髁突形态过小与颞下颌关节不可复性盘前移位之间的相关性。方法: 收集2015年3月~2016年3月来我科就诊的无明确已知病因的单侧髁突形态过小患者的临床及影像资料,对其临床特点、CBCT及MRI影像进行分析比较。结果: 共纳入42名患者(男9例,女33例)。平均年龄22.98岁。39名患者(92.86%)曾有TMD症状,34名患者(80.95%)存在TMD体征。CBCT显示形态过小侧与对侧髁突在前后径、髁头高度及髁突高度上差异有统计学意义(P<0.001)。MRI检查显示形态过小侧颞下颌关节不可复性盘前移位的比率明显高于对侧(P<0.001),并且变形及移位更严重。结论: 不可复性盘前移位可能是获得性髁突发育不良的风险因素之一。

Abstract: Objective: To explore the correlation between condylar hypoplasia and temporomandibular joint disc displacement without reduction. Methods: Clinical and imaging data of patients with unilateral condylar hypoplasia with no exact cause attending our hospital from March 2015 to March 2016 were collected. Their clinical data, CBCT, and MRI imaging results were analyzed. Results: Forty-two patients were included (9 males and 33 females), with the average age of 22.98 years old. Thiry-nine patients (92.86%) recalled TMD history, and 34 patients (80.95%) were detected signs of TMD. The hypoplastic condyle showed a statistically significant smaller in anteroposterior diameter, height of condylar head and condylar height by CBCT measurement compared with the contralateral condyles (P<0.001). MRI revealed the prevalence of disc displacement without reduction was significantly higher (P<0.001), and the degree of deformity and displacement of disc were more serious, in the hypoplastic condyle group than the contralateral side group. Conclusion: Disc displacement without reduction might be one of risk factors for acquired condylar hypoplasia.
