Radiofrequency ablation of laryngeal saccular cyst in infants: a series of six cases.

Saccular cysts of larynx are uncommon entity. These are infrequent causes of respiratory obstruction in neonates and infants. The saccular cysts are thought to arise in the saccule of the ventricle as a result of atresia of the ventricular orifice. The treatment options used in the management of saccular cysts are endoscopic needle aspiration, marsupialization and endoscopic extended ventriculotomy. We have found that removal of the saccular cyst can be achieved relatively safely and effectively by endoscopic radiofrequency ablation with improved surgical precision and better healing. We share our experience with a series of six cases, diagnosed under the sedation, thereafter radiofrequency ablation of laryngeal saccular cysts was done.
