摘　　要：目的探讨髁突矢状骨折(SFMC)的临床特征和治疗。方法对21例SFMC患者(23侧)的外伤情况、治疗方式、影像学资料进行了研究,并进行了随访。结果SFMC的主要的症状和体征是颞下颌关节区的疼痛(21/21)、张口受限(18/21)、前牙开(13/21)、咬合偏斜(12/21)。SFMC在2D-CT和3D-CT上具有明显的特征,对SFMC的诊断有重要的意义。所有患者治疗后下颌均能进行良好的前伸运动、侧向运动及开颌运动。结论SFMC应根据骨折片的移位情况和患者的年龄选择治疗方式,通过有效的治疗,髁突可以获得良好的功能。Objective To investigate the clinical characteristics and the treatments of the mandibular condylesagittal fracture. Methods 315 patients with fracture of mandible were investigated in the present study. Among them there were 21 cases （23 TMJs） diagnosed as sagittal fracture of the mandibular condyle. Diagnosed radiograghy included the panoramic radiograph, 2D-CT or 3D-CT scans. Treatments included surgery, maxilla-mandibular fixation （MMF） and functional therapy. Follow-up mandibular movements were recorded by digital calipers. Results The main clinical signs and symptoms of SFMC were pain in the TMJ area （21/21）, limited meuth-opening（ 18/21 ）, open-bite of front teeth（13/21）, deflective ecclusal contact（12/21） and so on. The images of 2D-CT and 3D-CT were characteristic and very valuable in diagnosis of SFMC. All patients had good protrusive, lateral protrusive or opening mevements after treatment. Conclusions The choice of therapies for SFMC varies with the dislocation of the fracture fragments and patients＇ age. After effective treatment, the TMJs with SFMC will have good functions.
