Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Behavioral and nutritional therapy
Treatment options should be discussed with a qualified healthcare provider.
Observation and Serial Assessments
Conservative management with regular monitoring of breathing patterns, feeding ability, and growth parameters in mild cases, as many infants improve spontaneously as they mature.
Positioning and Feeding Modifications
Elevating the head of the bed, using prone positioning when supervised, and modifying feeding techniques (smaller, more frequent feeds) to reduce respiratory distress during feeds.
Additional treatment options
Supraglottoplasty
Surgical procedure to remove or reshape redundant supraglottic tissue that collapses during inspiration, typically performed endoscopically to relieve airway obstruction.
surgicalAcid Reflux Management
When gastroesophageal reflux contributes to laryngomalacia symptoms, acid-suppressing medications or prokinetic agents may reduce inflammation and mucosal edema of the airway.
medicationTonsillectomy and Adenoidectomy
Surgical removal of enlarged tonsils or adenoids when upper airway obstruction from these tissues contributes to laryngomalacia symptoms and breathing difficulties.
