Conclusion:
Closed reduction is an effective and safe treatment method for arytenoid dislocation. Early closed reduction of arytenoid cartilage plays an important role in voice recovery.
Objective:
The study reviewed the clinical characteristics of arytenoid dislocation with the aim of identifying factors influencing voice recovery in the closed reduction of arytenoid dislocation.
Methods:
A retrospective chart review was performed at Chonnam National University Hospital for the period from January 2007 to March 2012.
Results:
Eleven patients with arytenoid dislocation were identified. The causes of arytenoid dislocation were intubation (n = 9) and blunt trauma (n = 2). All cases of arytenoid dislocations were treated by closed reduction. There were no major complications resulting from surgical intervention. Six of the 11 patients (54.5%) regained normal voice and vocal fold movement after closed reduction. Five patients (45.5%) had significant voice improvement postoperatively. In arytenoid dislocation due to blunt trauma, the duration between injury and voice improvement was much longer than in other causes of arytenoid dislocation (p = 0.012).

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
