Abstract

Subglottic stenosis, a laryngeal narrowing, can be either congenital or acquired. There are various anatomic abnormalities of the cricoid that explain the congenital types. The acquired type is due to prolonged intubation in 90% of cases. Anterior cricoid split can obviate the need for a tracheotomy in the neonate with minimal nonfibrotic subglottic stenosis. Laryngotracheal reconstruction allows correction of the more severely stenotic children. Both of these procedures strive to provide an adequate airway and a satisfactory voice.

摘要

声门下狭窄是一种喉部狭窄，可分为先天性或后天性。环状软骨存在多种解剖异常，这解释了先天性类型。在90%的病例中，后天性类型是由于长期插管所致。对于非纤维化程度较轻的新生儿声门下狭窄，环状软骨前裂开可避免气管切开术的需要。喉气管重建可矫正狭窄更严重的儿童。这两种手术都致力于提供足够的气道和令人满意的嗓音。
