Although laryngotracheal stenosis is well described in the literature, the vast majority of cases are of stenosis at either the subglottic or glottic level. Supraglottic stenosis is an unusual subset of laryngotracheal stenosis that has distinctly different causes, symptoms, and treatment options. ⋯ Supraglottic stenosis is a rare condition that is often associated with external-beam radiation or autoimmune disorders. All of the patients in our series experienced some degree of symptomatic airway obstruction that required management. The majority also had coexisting dysphagia, often associated with pharyngeal or esophageal stricture. Despite the favorable response to endoscopic treatment, all patients eventually required additional procedures because of symptomatic recurrence of their stenosis. Although endoscopic surgical treatment with a carbon dioxide laser in the operating room setting is a viable option, office-based treatment with a pulsed KTP laser appears to be an effective and potentially safer alternative.
