Arytenoid dislocation while using a McCoy laryngoscope.

Arytenoid dislocation (AD) involves either a complete disruption of the cricoarytenoid joint or a malpositioning of the arytenoid cartilages (AC) with reference to other laryngeal cartilages. In this report, we present a case of AD while using a McCoy laryngoscope. Although McCoy laryngoscope is recognized as a useful option for the cases of difficult endotracheal intubation, we are concerned that AD is likely with this device.
