ABSTRACT
Laryngomalacia is the term most broadly used to portray the "internal breakdown of structures of supraglottis of the larynx at the time of inspiration. It is often associated with stridor during inspiration, which is of a high pitch at the time of birth and comes into notice by 14 days. When there is an increase in breathing, stridor worsens, and it is usually position-dependent. Laryngomalacia means the weakening of the larynx resulting in a collapse of the laryngeal cartilages, especially the epiglottis, into the airway. This partially occludes the upper airway during inspiration and causes inspiratory stridor. The exact etiology of the condition is not known. It is a well-known cause of noisy breathing in neonates and infants. The common presentation is a neonate with flushing and high-pitched inspiratory stridor that is usually noticed before 14 days of age. This worsens with breathing and supine positioning and improves in a prone position. Less commonly, it can present with hypoxia, feeding problems, aspiration, and failure to thrive. The condition may increase in severity during early life but usually self-resolves by two years of age. The hiccup-like squeak of laryngomalacia during inspiration is due to unsettled air flowing through the laryngeal passage. The condition is diagnosed with laryngoscopy, and the treatment varies with presentation and severity. Neonates with the uncomplicated disease can be treated expectantly. Those presenting with feeding problems and gastroesophageal reflux will require acid suppression. Severe complications like aspiration, severe airway obstruction, and hypoxia will require surgical treatment, including supraglottoplasty. In cases where the surgical treatment failed, noninvasive ventilation can be advised. The article reviews the various medical and surgical interventions and the management of severe laryngomalacia.
