目的：我们讨论了先前描述的歌唱声音中存在的局灶性喉张力障碍的发音特征。方法：我们对一家神经喉科转诊中心的5例辛格氏肌张力障碍患者进行回顾性分析。结果：4例患者表现出与唱歌声音中的内收肌痉挛性发声障碍一致的发音特征。1例患者唱歌时表现出外展肌痉挛性发声障碍。每位患者最初在会话语音中表现出正常的连接语音。讨论了治疗方案和结果，包括肉毒杆菌毒素的使用。结论：辛格氏肌张力障碍是一种以前未被描述的神经障碍，应该被那些治疗声音表演者和声音障碍的人所理解。
Objectives: We discuss the phonatory characteristics of a previously undescribed focal laryngeal dystonia present in the singing voice. Methods: We performed a retrospective chart review of 5 patients with singer's dystonia at a neurolaryngology referral center. Results: Four patients reviewed demonstrated phonatory characteristics consistent with adductor spasmodic dysphonia present in their singing voice. One patient demonstrated abductor spasmodic dysphonia in the singing voice. Each patient initially exhibited normal connected speech in conversational voicing. The treatment protocol and outcome are discussed, including the use of botulinum toxin. Conclusions: Singer's dystonia is a previously undescribed neurologic disorder that should be understood by those who treat voice performers and voice disorders.
