Subglottic stenosis (SGS) is defined as narrowing of the airway below the vocal cords and is a potentially life-threatening condition. Many aetiologies have been proposed in the literature for subglottic stenosis, the most common being post-intubation and post-tracheostomy stenosis. Less frequent causes include infection, gastroesophageal reflux disorder (GERD), systemic diseases, radiation therapy, inhalational injury, occupational exposures, primary and secondary tracheal malignancies, congenital conditions, and idiopathic [1].
