Congenital laryngeal saccular cyst of the newborn.

Congenital laryngeal saccular cysts of the newborn frequently cause severe dyspnea and upper respiratory tract obstruction. When confronted with this emergency situation necessary therapeutic action may consist of intubation, puncture or incision to reduce the volume of the cyst or tracheotomy. The CO2 laser was effectively used not only to incise the supraglottic saccular cyst but also to vaporize the lining.
