Hemimasticatory spasm is a rare disorder characterized by paroxysmal involuntary contraction of the jaw-closing muscles. As the ideology and pathogenesis of the disease are still unclear, there has been no treatment that could give rise to a good outcome so far. Herein, we tried to use surgical management to cure the disease. Six patients with the disease were included in this study. These patients underwent microvascular decompression of the motor fibers of the trigeminal root. After the operation, all faces of the patients felt relaxed at varied degrees, except for 1 patient. Our study showed that microvascular decompression of the trigeminal nerve could lead to a better outcome. However, a control study with a large sample is needed before this technique is widely used.
偏侧咀嚼肌痉挛是一种罕见的疾病，其特征为下颌闭合肌的阵发性不自主收缩。由于该疾病的病因和发病机制仍不清楚，迄今为止尚无能产生良好疗效的治疗方法。在此，我们尝试采用手术治疗来治愈该疾病。本研究纳入了6例患有该疾病的患者。这些患者接受了三叉神经根运动纤维的微血管减压术。术后，除1例患者外，所有患者的面部均有不同程度的放松感。我们的研究表明，三叉神经微血管减压术可带来更好的疗效。然而，在该技术广泛应用之前，还需要进行大样本的对照研究。
