Management of Congenital Laryngomalacia and Airway Obstruction

Congenital laryngomalacia is the most common cause of inspiratory stridor in neonates, arising from excessive collapsibility of supraglottic structures during inspiration. Clinical severity ranges from benign, self-resolving noise to life-threatening airway compromise with feeding difficulties, failure to thrive and hypoxaemia. Initial assessment requires systematic airway evaluation, monitoring of growth and multidisciplinary input from otolaryngology, respiratory medicine and nutrition specialists. Mild cases without feeding or respiratory compromise may be managed conservatively with positional measures and nutritional support. Medical therapy, notably acid suppression for accompanying gastro-oesophageal reflux, can alleviate secondary inflammation and improve symptoms. In severe presentations, surgical intervention is guided by endoscopic findings: supraglottoplasty remains the standard procedure, employing cold-steel or laser techniques to trim redundant aryepiglottic folds and epiglottis and stabilise supraglottic collapse. Outcomes are favourable when comorbidities are minimal, though persistent aspiration or synchronous airway lesions may warrant extended follow-up. Advances in non-invasive ventilation offer adjunctive support for postoperative recovery or in cases refractory to surgery, while long-term surveillance ensures early detection of residual obstruction or feeding disorders.

Management of Congenital Laryngomalacia and Airway Obstruction publication trend

The graph below shows the total number of articles in management of congenital laryngomalacia and airway obstruction across all publications each year (not limited to Nature Index journals).

Technical terms

Congenital laryngomalacia: A developmental anomaly of supraglottic structures causing inspiratory collapse and stridor in infants.

Stridor: High-pitch respiratory sound produced by turbulent airflow through a narrowed airway during inspiration.

Supraglottoplasty: Surgical procedure to remove or reshape redundant supraglottic tissues to stabilise the airway.

Synchronous airway lesions (SALs): Coexisting malacia of the trachea or bronchi that can exacerbate airway obstruction in laryngomalacia.

Gastro-oesophageal reflux: Retrograde flow of stomach contents into the oesophagus, often aggravating laryngeal inflammation and stridor.
