目的探讨下颌支高度与面肌短小症患者咀嚼肌功能的关系。设计回顾性研究影像学和生理资料。影像和生理数据来源于札幌医科大学附属医院的记录。患者共29例表现为Pruzansky级I、II级畸形的面肌短小症患者。主要观察指标采用多排计算机断层扫描评估下颌支高度和咀嚼肌体积。采用K7评价系统测定肌电图值。根据患侧与未患侧的下颌支高度比将患者分为3组：0组，0组，0组，1.00组；第一组，1.00 ~ 0.85；第二组，< 0.85。采用Tukey-Kramer方法和game - howell方法确定参数之间的相关性。结果下颌支高度降低与患侧咬肌肌电图值降低（P < 0.05）及最大开口时下颌外侧偏移量显著相关（P < 0.05）。这些差异在第2组单侧面肌短小症患者中更为明显。结论下颌支高度降低可引起患侧咬肌功能障碍，而非颞肌功能障碍。
Objective To clarify the relationship between mandibular ramus height and function of masticatory muscles in patients with hemifacial microsomia. Design Retrospective study of imaging and physiological data. Setting Images and physiological data were obtained from the records of Sapporo Medical University Hospital. Patients A total of 29 patients with hemifacial microsomia who showed Pruzansky grades I, II deformity. Main Outcome Measures Mandibular ramus height and masticatory muscle volume were evaluated with multi-detector row computed tomography. The electromyographic value was measured by the K7 Evaluation System. The hemifacial microsomia patients were classified into three groups based on the mandibular ramus height ratio of the affected and unaffected sides: group 0, > 1.00; group 1, 1.00 to 0.85; group 2, < 0.85. The Tukey-Kramer method and Games-Howell method were used to determine correlations between parameters. Results Decreased mandibular ramus height was significantly correlated with both reduced electromyographic values of the masseter muscle (P < .05) and the amount of mandibular lateral deviation at the time of maximum opening (P < .05) on the affected side. These differences were prominent in unilateral hemifacial microsomia patients classified as group 2. Conclusions Decreased mandibular ramus height may cause dysfunction of the masseter muscles but not the temporal muscle on the affected side in patients with hemifacial microsomia.
