Abstract

Laryngomalacia is the most common congenital anomaly of the larynx in neonates. This supraglottic obstruction leads to increased work of breathing and stridor. The most common associated symptoms are swallowing dysfunction, regurgitation, cough, and sleep-disordered breathing. Spontaneous improvement usually occurs over a period of 12 months to 2 years although the majority of cases of laryngomalacia bnegins its course without any long-term sequel. Despite its benign characteristics, 10% of cases require intervention. Nowadays, the treatment consists of either wait-and-see or surgery. For severe laryngomalacia, supraglottoplasty has become the mainstay of surgical management. In this study, we report 3 cases of laryngomalacia in neonates, where patients underwent supraglottoplasty using the carbon dioxide laser without tracheostomy under conventional ventilation.
