Arytenoid cartilage dislocation is an infrequently diagnosed cause of vocal fold immobility. Seventy-four cases have been reported in the literature to date. Intubation is the most common origin, followed by external laryngeal trauma. Decreased volume and breathiness are the most common presenting symptoms. We report on 63 patients with arytenoid cartilage dislocation treated by the senior author (RTS) since 1983. Significantly more posterior than anterior dislocations were represented. Although reestablishing joint mobility is difficult, endoscopic reduction should be considered to align the heights of the vocal processes. This process may result in significant voice improvement even long after the dislocation. Strobovideolaryngoscopy, laryngeal electromyography, and laryngeal computed tomography (CT) imaging are helpful in the evaluation of patients with vocal fold immobility to help distinguish arytenoid cartilage dislocation from vocal fold paralysis. Familiarity with signs and symptoms of arytenoid cartilage dislocation and current treatment techniques improves the chances for optimal therapeutic results.
杓状软骨脱位是一种较少被诊断出的声带运动障碍病因。迄今为止，文献中已报道了74例病例。插管是最常见的病因，其次是外部喉部创伤。音量降低和呼吸音是最常见的症状。我们报告了自1983年以来由资深作者（RTS）治疗的63例杓状软骨脱位患者。后脱位的病例明显多于前脱位。尽管恢复关节活动度很困难，但应考虑进行内镜下复位以对齐声带突的高度。即使在脱位很久之后，这个过程也可能显著改善嗓音。频闪喉镜检查、喉肌电图检查和喉部计算机断层扫描（CT）成像有助于评估声带运动障碍患者，以帮助区分杓状软骨脱位和声带麻痹。熟悉杓状软骨脱位的体征和症状以及当前的治疗技术可提高获得最佳治疗效果的机会。
