The laryngocele and saccular cyst are uncommon anomalies of the larynx. Two patients, one with an Intemal laryngocele and one with a saccular cyst, were successfully treated by endoscopic laser marsupialization of their lesions. Since neither patient was found to be a suitable candidate for prolonged general anesthesia, the patients did not require a tracheotomy and were discharged the day after surgery. Both patients are doing well, with remarkable Improvement in their voices persisting in their three year follow-up. The signs, symptoms, diagnosis, treatment, and Indications for endoscopic laser treatment of Intemal laryngoceles and saccular cysts are discussed. Laser marsupialization of Intemal laryngoceles appears to be an acceptable mode of treatment.
