Cricoarytenoid subluxation, computed tomography, and electromyography findings. 1987

L G Close, and M Merkel, and B Watson, and S D Schaefer

A case of cricoarytenoid subluxation secondary to endotracheal intubation and documented by computed tomography (CT) and electromyography (EMG) is reported. Successful endoscopic reduction of the displaced arytenoid is confirmed by CT. The normal anatomy and physiology of the cricoarytenoid joint is presented and the literature regarding this rarely reported injury is reviewed. Based on this review and the case reported, a treatment plan is proposed.
