下半部痉挛
What is Hemifacial Spasm?
半面痉挛是一种神经肌肉疾病ed by frequent involuntary contractions of the muscles on one side of the face. It is rarely seen on both sides of the face. Both men and women may suffer from hemifacial spasm, but the condition occurs more often in middle-aged and elderly women, and more frequently in the Asian population.
虽然通常不会疼痛，但下摆痉挛会干扰正常的面部表情。在某些人中，它会影响视力并干扰日常活动，例如驾驶，工作和睡眠，并以其他方式对生活质量产生负面影响。

Causes of Hemifacial Spasm
面神经损伤或肿瘤可能会导致半毛痉挛，但通常是由于血管压在其离开脑干的地方引起的。这种情况也可能没有明显的原因。
下摆痉挛和诊断的症状
Hemifacial spasm typically begins with intermittent twitching of the eyelid and muscles around the eye that causes the eye to close. The spasm may spread gradually to the muscles in the lower face and can pull the mouth to one side. Eventually, the spasm may involve all of the muscles on one side of the face almost continuously. Other less common symptoms include a clicking sound in the ear, hearing loss, ear pain, and vision impairment.
因为在其他医疗状况下也可能发生半径痉挛的症状，因此通常需要进行多种测试以确保准确的诊断。它们可能包括对眼睛，视力，肌肉力量和反射的神经检查；记录和测量肌肉的电活动的肌电图；MRI和/或CT扫描；和血管造影，使用对比染料的血管X射线。
Treatment
有些人在注射肉毒杆菌毒素A（Botox®）的情况下变得相对没有症状。微血管减压是一种手术治疗，可以减轻对面神经的压力并改善半径痉挛。与所有手术一样，必须仔细权衡风险与收益。
