Otolaryngologists are frequently asked to evaluate patients who are endotracheally intubated and remain difficult to extubate or have voice or airway complaints after being extubated. (entokey.com)
Often, these nerves are not the only ones affected and therefore incoordination or failure of function of nerves supplying other parts of the voice box can contribute to food or water gaining access to the airway during swallowing and altered barking/mewing. (uk.net)

An assistant should be available to observe per os the size of the laryngeal opening achieved to ensure that adequate abduction of the laryngeal cartilages has been obtained. (vin.com)
Synonyms: Cartilago thyreoidea This is the largest of the laryngeal cartilages and it is made of two smooth laminae of which the two lower thirds fuse in the midline, while the most superior third remains unfused and creates the laryngeal notch. (columbia.edu)
