Hemimasticatory spasm is a very rare disorder of the trigeminal nerve characterized by paroxysmal involuntary contraction of the jaw-closing muscles. The mechanisms leading to hemimasticatory spasm are still unclear. Recently, injection of botulinum toxin has become the treatment of choice due to its excellent results. We report a case of a successful treatment of hemimasticatory spasm via microvascular decompression of the motor branch of the trigeminal nerve.
半侧咀嚼肌痉挛是一种非常罕见的三叉神经疾病，其特征是下颌闭合肌的阵发性不自主收缩。导致半侧咀嚼肌痉挛的机制尚不清楚。最近，由于其优异的效果，肉毒杆菌毒素注射已成为治疗的首选。我们报告了一例通过三叉神经运动支微血管减压成功治疗半侧咀嚼肌痉挛的病例。
