Arytenoid cartilage dislocation can occur as a complication of tracheal intubation and laryngeal trauma, but its occurrence with indirect video laryngoscopy has not been reported. This paper reports anterior arytenoid dislocation occurring after nasotracheal intubation performed under indirect laryngoscopy using a video laryngoscope (McGRATH MAC; Medtronic). The dislocation is presumed to have resulted from the laryngoscope blade being initially inserted too deeply and applying pressure to the posterior aspect of the left cricoarytenoid joint. This patient's anterior arytenoid dislocation was treated conservatively using speech therapy with resolution occurring approximately 40 days postoperatively. On the 74th day after surgery, fibroscopic examination confirmed recovery and healing of the dislocation. However, other types of arytenoid dislocations and laryngeal injuries may require alternative treatment. Early consultation with an otolaryngologist is recommended if arytenoid dislocation is suspected.
杓状软骨脱位可发生于气管插管和喉外伤等并发症中，但在间接喉镜下使用视频喉镜进行经鼻气管插管后发生杓状软骨脱位尚未见报道。本文报道了 1 例使用视频喉镜（麦克格雷斯 MAC；美敦力）在间接喉镜下经鼻气管插管后发生的前位杓状软骨脱位。脱位可能是由于喉镜叶片最初插入太深并对左侧环杓关节后外侧施加压力所致。该患者的前位杓状软骨脱位采用言语治疗进行保守治疗，术后约 40 天症状缓解。术后 74 天，纤维喉镜检查证实脱位已恢复愈合。然而，其他类型的杓状软骨脱位和喉损伤可能需要其他治疗方法。如果怀疑发生杓状软骨脱位，建议尽早咨询耳鼻喉科医生。
