Servicio de Anestesiología y Reanimación, Complejo Hospitalario Universitario A Coruña, A Coruña, Spain. Electronic address:

Vocal cord paralysis is a rare but severe complication after orotracheal intubation. The most common cause is traumatic, due to compression of the recurrent laryngeal nerve between the orotracheal tube cuff and the thyroid cartilage. Other possible causes are direct damage to the vocal cords during intubation, dislocation of the arytenoid cartilages, or infections, especially viral infections. Read More
