Abstract:

Arytenoid cartilage dislocation (ACD) is a rare and often overlooked complication of tracheal intubation or blunt laryngeal trauma. Its most common symptom is persistent hoarseness. Procedures, such as pharyngeal intubation, examination, monitoring, and treatment, are potential factors that can lead to ACD. This article reports three cases at Weihai Municipal Hospital, Shandong University; the patients occurred ACD following laparoscopic gastrointestinal surgery under general anesthesia; the patients exhibited symptoms such as hoarseness, choking cough, and dysphonia after surgery; nebulization treatment was ineffective; otolaryngologists were consulted, and the patients were diagnosed as ACD; the patients recovered after manipulative repositioning and voice training by the otolaryngologists. In this paper, the causes and prevention measures of ACD are analyzed.

摘要：

杓状软骨脱位（arytenoid cartilage dislocation，ACD）是气管插管或喉钝挫伤的一种罕见且经常被忽视的并发症，最常见的症状是持续性声音嘶哑。咽喉部置管、检查、监测、治疗等操作均是引发ACD的潜在因素。本文报道山东大学附属威海市立医院3例患者，于全麻腹腔镜胃肠手术后出现声嘶、呛咳、发音困难等症状，雾化治疗无效，请耳鼻喉医生会诊，确诊为ACD。经耳鼻喉医生手法复位和语音训练，患者康复。本文就ACD的发生原因和防治措施进行了分析。
