ANSWER AND REASONINGB. Microlaryngobronchoscopy to exclude synchronous lesions and supraglottoplasty in an experienced paediatric airway service
Severity is determined by physiology and feeding/growth, not noise alone; supraglottoplasty is appropriate after evaluation for multilevel disease.
Why every option is right or wrong
A. Reassurance alone because all laryngomalacia resolves: Hypoxaemia and growth failure define severe disease.
B. Microlaryngobronchoscopy to exclude synchronous lesions and supraglottoplasty in an experienced paediatric airway service: Severe symptomatic laryngomalacia warrants full airway assessment and surgical relief; feeding and comorbidity assessment are integral.
C. Adenoidectomy: Adenoids do not cause neonatal dynamic supraglottic collapse.
D. Blind nasogastric feeding without airway assessment: Nutrition support may be needed but does not correct critical obstruction.
E. Long-term antibiotics: There is no bacterial process.
What if the scenario changed?
If the infant fed and grew normally without recession or desaturation, observation with safety-netting would usually be preferred.
