Recurrent croup is a good indicator of underlying paediatric airway issues: A 10-year retrospective cohort study of airway endoscopy.

Surgeons and parents can be reassured that rigid airway endoscopy for children with recurrent croup demonstrated high diagnostic utility but will rarely lead to further surgical intervention. Greater understanding about recurrent croup may require consensus clarification about definitions of recurrent croup and/or a universal adoption of a minimum standard operative record or grading system after rigid endoscopy for recurrent croup.
