Description
Two cases of anterior cricoarytenoid subluxation, referred to our voice clinic since the clinic opened 13 years ago, were reported. The diagnosis, evaluation of phonatory function, follow-up, and treatment strategies for this disease were discussed. Both cases showed spontaneous repositioning after 1 and 4 months of occurrence, respectively, during the evaluation of phonatory function and preparation for a repositioning operation. Both cases showed an increased glottal flow and an elevated fundamental frequency, and these abnormalities also improved after the spontaneous reposition. Other cases of cricoarytenoid subluxation and spontaneous reposition have been reported, especially cases of anterior subluxation. The mechanism of spontaneous repositioning in anterior subluxation is thought to be due to the frequent use of the posterior cricoarytenoid muscle, which is the only muscle for glottal opening. For the diagnosis and treatment of cases with laryngeal symptoms after tracheal intubation or cervical injury, careful differential diagnosis and treatment planning should be based on radiological examination, phoniatric evaluation, and electrophysiological examination, not only on history and endoscopic findings.
