Inspiratory stridor of newborns and infants admitted to a paediatric ENT outpatient clinic: diagnostic approach and therapeutic outcome

The main objective was to analyse the use of rigid laryngotracheoscopy under general anaesthesia (GA) and endoscopic surgery in the management of inspiratory stridor in patients referred to a paediatric ENT outpatient clinic. The secondary objective was to analyse the aetiological diagnoses made and their therapeutic management. This is a prospective study including all newborns and infants, corresponding to 190 patients, presenting for the first time in consultation for inspiratory stridor from January 2015 to December 2017. A consultation form was filled out after each consultation and added to a database; a management algorithm was used to determine which patients required a rigid laryngotracheoscopy. A 17.9% ( n = 34) of the patients required rigid laryngotracheoscopy, of whom 12.6% ( n = 24) underwent concomitant endoscopic surgery. A 65.8% ( n = 125) of the patients were diagnosed with laryngomalacia, 21.1% ( n = 40) with isolated posterior excess of mucosa, 9.5% ( n = 18) with another diagnosis and 3.7% ( n = 7) with a normal examination. The presence of comorbidity was associated ( p
