Supraglottoplasty in children with obstructive sleep apnea

Abstract

Supraglottoplasty involves the reshaping or removal of obstructive tissue from the upper larynx. This procedure is commonly done for patients with laryngomalacia when the airway obstruction from laryngeal collapse is significant enough to cause obstructive sleep apnea (OSA). Supraglottoplasty may involve the epiglottis, the aryepiglottic folds and the postglottis. Supraglottoplasty can be done using cold steel, CO₂ laser, or coblation. Supraglottoplasty is considered an effective treatment for OSA in some children. The procedure has a high success rate, few complications, and often results in reduction of sleep and breathing symptoms. This article will discuss the indications, technique, and complications of supraglottoplasty.
