  • Title: Glottic and subglottic stenosis from endotracheal intubation.
    Author: Hawkins DB.
    Journal: Laryngoscope; 1977 Mar; 87(3):339-46. PubMed ID: 839929.
    Abstract:
    As a result of increased use of prolonged endotracheal intubation, complications of intubation are now being seen more often. Stenosis of the airway may develop at the level of the glottic or subglottic larynx, or in the trachea. Discussions of management do not always distinguish clearly between laryngeal stenosis and tracheal stenosis. Yet, these are two separate entities. Discussions of laryngeal stenosis usually deal with subglottic stenosis, with less emphasis on obstruction at the glottic level. Of 20 patients, 14 adults and six children, with stenosis of the larynx secondary to intubation, we were successful in establishing adequate airways in 16. An analysis of these 20 patients leads to the following conclusions: 1. Scarring in the glottic posterior commissure between the arytenoid cartilages is a frequent cause of laryngeal stenosis after intubation. 2. Endoscopic management can be successful in many cases if it is started early enough, and repeated as often as is necessary. The earlier it is begun, the better the results will be. 3. Indwelling stents which are extremely valuable in laryngeal stenosis from external trauma, may not be as useful in stenosis from endotracheal tube trauma.
