Two Cases of Laryngomalacia With Congenital Vallecular Cyst Treated by Supraglottoplasty

Abstract

Vallecular cyst consisted of a unilocular cystic mass of variable size arising from the lingual surface of the epiglottis and containing clear fluid is a rare occurrence in children. Although a cyst is benign, it may cause serious airway obstruction and even death if not treated appropriately. Also, laryngomalacia is the most common congenital anomaly that causes inspiratory stridor and airway obstruction in the newborn. Symptoms typically begin to appear at around 2 to 3 weeks of age and become worse between 4 and 8 months. With a review of literature, we report two cases of vallecular cyst with symptomatic laryngomalacia in a 1-month-old female and a 2-month-old male. Both patients experienced symptom relief after undergoing endoscopic supraglottoplasty.
