Hemifacial spasm (HFS) is a frequent disorder characterized by involuntary contractions of those muscles innervated by the facialis nerve on one side of the face. The symptoms can appear as tonic or clonic, intermittent or permanent. Diagnosis is based purely on clinical observation. Differential diagnosis should rely on cranial MRI, which can demonstrate a pathological contact between the nerves and vessels and exclude alternative causation. Often, the symptoms are not marked so that therapy may not be necessary. The therapy of choice is an injection of botulinum toxin to reduce the underlying pathological activity. As an alternative, decompression operation according to Jannetta can be considered, although it is frequently rejected by patients.
面肌痉挛（HFS）是一种常见疾病，其特征为面部一侧面神经支配的肌肉出现不自主收缩。症状可表现为强直性或阵挛性、间歇性或持续性。诊断完全基于临床观察。鉴别诊断应依靠头颅磁共振成像（MRI），其可显示神经与血管之间的病理性接触并排除其他病因。通常，症状并不明显，因此可能无需治疗。首选治疗方法是注射肉毒杆菌毒素以降低潜在的病理活动。作为替代方案，可考虑根据詹内塔（Jannetta）方法进行减压手术，不过患者常常拒绝这种手术。
