| 摘 要： | 目的：应用CT和肌电图评价A型肉毒毒素治疗后咬肌的厚度与电生理变化．方法：对入选的20例（40侧）咬肌肥大患者进行A型肉毒毒素肌肉注射治疗．咬肌肥大就医者每侧注射剂量为5万U／L．观察治疗前后不同时期就医者咬肌厚度变化情况、不良反应或并发症发生情况以及电生理的改变．结果：20例患者注射后CT与传统B超测量的咬肌厚度无明显差异．测量结果显示：不同时期的咬肌厚度均明显小于注射前，差异有统计学意义（P〈0．01）．药物注射后4～12wk咬肌厚度减小最明显，12wk后咬肌的力量与体积逐渐恢复，24wk后肌力基本恢复正常，但咬肌体积的恢复各不相同．肌电变化显示：不同时期的运动单位电位幅度均较治疗前减小（P〈0．01）．20例患者总体满意率为85％．结论：CT和肌电图对A型肉毒毒素治疗良性咬肌肥大的疗效可以进行很好的评价．
