ConclusionClosed reduction is effective and safe for the treatment of arytenoid dislocation, and the selection of an appropriate time window to perform closed reduction is crucial in achieving relatively stable treatment outcomes and short treatment duration.ObjectiveThe aim of this study was to investigate whether there is an appropriate time window to perform closed reduction for unilateral arytenoid dislocation caused by intubation.MethodsA retrospective chart review was carried out for the cases collected from September 2014 to May 2016 at Second Affiliated Hospital of Zhejiang University, China.ResultsThirty-five patients with arytenoid dislocation were identified. Endotracheal intubation was the cause for 33 of the patients and gastric tube caused arytenoid dislocation in two patients. The patients were treated by closed reduction, and no major complications resulting from surgical intervention were observed. All patients regained normal voice and vocal fold movement after the surgery, except one patient who recovered spontaneously. As one of the most significant findings in the current study, we observed the relatively stable treatment outcomes and shortened recovery duration were obtained in the patients treated during a period between the 13th day and 26th day after arytenoid dislocation.
