杓状体半脱位和喉返神经麻痹（RLNP）均可由喉损伤引起，临床上难以区分。一位最初被认为患有RLNP的杓状关节半脱位患者在受伤1年后接受了中间化喉成形术治疗。术前磁共振成像和计算机断层扫描有效地证实了环杓状肌半脱位，术中肌电图（EMG）显示甲状腺杓状肌电活动正常。术前纤维喉镜检查的照片用于鉴别杓状体半脱位的外观。本文介绍了两例RLNP患者的计算机断层扫描结果和喉镜照片，并通过术中肌电图评估来帮助区分这种疾病与杓状体半脱位的临床表现。一个综合的方法来诊断和治疗类蝶关节半脱位提出。
Both arytenoid subluxation and recurrent laryngeal nerve paralysis (RLNP) may result from injury to the larynx, and they may be difficult to distinguish clinically. A patient with arytenoid subluxation who was initially believed to have RLNP was treated with medialization laryngoplasty 1 year after the injury. Preoperative magnetic resonance imaging and computed tomography effectively demonstrated the cricoarytenoid subluxation, which was confirmed by intraoperative electromyography (EMG) showing normal electrical activity in the thyroarytenoid muscle. Photographs from preoperative fiberoptic laryngoscopy are presented to identify the appearance of arytenoid subluxation. Computed tomographic findings and photographs from laryngoscopy of two patients with RLNP documented by intraoperative EMG evaluation are presented to help distinguish the clinical appearance of this disorder from arytenoid subluxation. An integrated approach to the diagnosis and treatment of arytenoid subluxation is presented.
