Laryngeal complications secondary to nasogastric intubation have been reported rarely in recent literature. Recent experience with three patients who developed laryngeal injuries related to nasogastric tubes prompted retrospective, experimental, and prospective studies to determine the mechanism of laryngeal injury. A review of the literature, as well as the clinical findings in our three patients, point to midline tube placement and the subsequent development of cricoid chondritis as the underlying etiology. An experimental study using anesthetized dogs was designed to compare histologically the effect on the larynx with nasogastric tubes placed in the midline, as opposed to nasogastric tubes in the lateral position. Results of the histologic study confirmed that midline tubes generate severe inflammation in the postcricoid region. One hundred patients were then evaluated roentgenographically to determine the incidence of midline tube placement in a random sample. Six percent of the patients had nasogastric tubes in the midline. Patients who have nasogastric tubes in place for more than three days or have a severe amount of discomfort should have an x-ray film to determine position of the tube. Midline tubes should be removed or replaced.
