Synopsis

Narrowing of the subglottic region of the larynx. Usually acquired, but can be congenital. Acquired subglottic stenosis is most commonly caused by iatrogenic trauma, where airway damage from intubation or tracheotomy leads to the narrowing. Can be associated with stridor and dyspnea. Other findings include cyanosis, cough, hoarseness, epistaxis, voice changes, and saddle nose deformity (if autoimmune vasculitis related). Acquired cases tend to be more severe. Congenital cases usually improve as the child grows. More frequently found in women.

Therapy predominantly requires endoscopic surgical dilation of the airway and may ultimately require open airway reconstruction or tracheostomy.
