摘　　要：目的:分析髁突囊内骨折软组织损伤的类型及保守治疗后发生颞下颌关节强直的因素。方法:将某医院收治的髁突囊内骨折未行手术治疗13例患者(18个髁突囊内骨折)纳入研究,收集受伤后及半年后下颌骨CT及MRI图像资料,利用MRI对软组织损伤进行分类和随访。结果:13例患者的18个髁突囊内骨折有3例发生不同程度的颞下颌关节强直,其中2例为单侧,1例为双侧。结论:CT及MRI是正确有效的诊断方法。保守治疗过程,早期进行功能锻炼,有利于张口度的恢复以及防止髁突运动障碍。Objective:To analyze the type of soft tissue injury and the causes of TMJ ankylosis after conservative treatment.Methods:18 cases of intracapsular condylar fractures were included in the study,CT and MRI images of mandible were collected,MRI was used to classify and follow up the soft tissue injury.Results:Among the 18 fractures in 13 patients,3 had ankylosis of TMJ,2 of them were unilateral and 1 of them were bilateral.Conclusion:CT and MRI are correct and effective diagnostic methods.Conservative treatment and early functional exercise are beneficial to the recovery of opening degree and the prevention of condylar dyskinesia.
