Saccular cyst of the larynx in infants.

A saccular or congenital cyst of the larynx is a mucus-filled dilatation of the laryngeal saccule and can distort the aryepiglottic fold, the false cord or the laryngeal ventricle. The most common symptom of the laryngeal cyst is respiratory distress with inspiratory stridor and the diagnosis can usually be made by laryngoscopy. Treatment includes incision and drainage together with extirpation of the cranial wall of the cyst through a laryngoscope. Sometimes tracheostomy is also needed. Usually there are no complications afterwards and the development of these infants is perfectly normal. Our 3 cases and clinical features of this very unusual disorder are presented.
