We report two cases of hemimasticatory spasm in association with progressive hemifacial atrophy. On the basis of neurophysiological and magnetic resonance imaging assessments, a peripheral irritation of the trigeminal nerve--probably due to entrapment of the motor branches in the infratemporal fossa--is suggested as the cause of the involuntary movement. Local injections of botulinum toxin type A into the masticatory muscles proved to be a successful treatment in both patients.
我们报告了两例与进行性半侧面部萎缩相关的偏侧咀嚼肌痉挛病例。基于神经生理学和磁共振成像评估，提示三叉神经的外周刺激——可能是由于颞下窝运动分支受压——是这种不自主运动的原因。对两名患者而言，向咀嚼肌局部注射A型肉毒杆菌毒素被证明是一种成功的治疗方法。
