Aryepiglottic Cyst Developed Hours After Tracheal Intubation Causing Acute Upper Airway Ball-Valve Obstruction: A Case Report

This is the authors' abstract. We don't add key points for this paper.

This is the first case report describing an aryepiglottic cyst resulting in critical airway compromise after an uneventful tracheal intubation. We present the case of a 55-year-old woman who developed acute dyspnea and stridor several hours after the surgery. She was found to have significant upper airway obstruction owing to a large left aryepiglottic cyst with a ball-valve effect.
