Arytenoid cartilage dislocation is considered as a rare laryngeal injury and closed reduction is commonly used as the first choice for the arytenoid dislocation. However, the tools of closed reduction vary, and there is no dedicated tool for closed reduction, and the treatment outcome varies from person to person. This study compared the treatment outcome of the modified laryngeal forceps and traditional laryngeal forceps. This study conformed to the strengthening the reporting of observational studies in epidemiology guidelines regarding retrospective studies. From May 2021 to February 2023, the records of 28 patients with arytenoid cartilage dislocation caused by endotracheal intubation were reviewed. They were divided into the traditional group ( = 14) and the modified group ( = 14) by gender. Indirect or direct laryngoscopy, video stroboscopy, high-resolution computed tomography, and cricoarytenoid joint 3-dimensional reconstruction were used to evaluate arytenoid position and motion. Clinical characteristics, voice function, procedural skill, and treatment outcome for each case were recorded. Each patient was diagnosed with arytenoid dislocation caused by endotracheal intubation. There was no significant difference in the treatment outcome between the traditional group and the modified group ( .05). However, the median time interval between closed reduction and the return of normal voice in the traditional group was 31.08 ± 10.56 days, which was significantly longer than the median time of 17.92 ± 3.83 days in the modified group ( < .05). Closed reduction with the modified laryngeal forceps under local anesthesia is an effective and safe procedure. Compared with traditional laryngeal forceps, the modified laryngeal forceps can shorten the treatment duration.
杓状软骨脱位被认为是一种罕见的喉部损伤，闭合复位通常被用作杓状软骨脱位的首选治疗方法。然而，闭合复位的工具各不相同，且没有专门用于闭合复位的工具，治疗效果因人而异。本研究比较了改良喉钳与传统喉钳的治疗效果。本研究符合加强流行病学观察性研究报告中关于回顾性研究的指南。回顾了2021年5月至2023年2月期间28例因气管插管导致杓状软骨脱位患者的记录。根据性别将他们分为传统组（n = 14）和改良组（n = 14）。采用间接或直接喉镜检查、频闪喉镜检查、高分辨率计算机断层扫描以及环杓关节三维重建来评估杓状软骨的位置和活动情况。记录每个病例的临床特征、嗓音功能、操作技巧和治疗效果。每位患者均被诊断为气管插管导致的杓状软骨脱位。传统组和改良组的治疗效果差异无统计学意义（P>0.05）。然而，传统组闭合复位至嗓音恢复正常的中位时间间隔为31.08±10.56天，显著长于改良组的中位时间17.92±3.83天（P<0.05）。局部麻醉下使用改良喉钳进行闭合复位是一种有效且安全的操作。与传统喉钳相比，改良喉钳可缩短治疗时间。
