INTRODUCTION. Airway abnormalities are rare but potentially fatal. Stridor is a respiratory noise with greater predominance in the inspiratory phase. OBJECTIVE. To evaluate the etiology of stridor, determine its comorbidities and mortality. MATERIALS AND METHODS. Retrospective cross-sectional study. Population of 110 and sample of 33 data from the Medical Records of neonatal or infant patients who presented stridor at the Carlos Andrade Marín Specialties Hospital of Quito-Ecuador, from january 2009 to december 2020. RESULTS. The 51,51% (17; 33) of cases were men. The age of the first consultation for stridor was within the first month in 18,00% (6; 33) and 40,00% (13; 33) at 3 months. The most frequent congenital laryngeal pathology was: laryngomalacia 81,82% (27; 33), followed by subglottic stenosis 9,09% (3; 33), bilateral chordal paralysis 6,06% (2; 33) and tracheal stenosis 3,03% (1; 33). The 51,51% (17; 33) presented comorbidities of causes: neurological, pulmonary and genetic among the main ones. Mortality was 18,20% (6; 33) related to the severity of comorbidities, except one secondary to tracheal stenosis. CONCLUSION. Laryngomalacia and subglottic stenosis were the predominant pathologies with congenital stridor. The comorbidities that occurred were neurological, pulmonary, genetic and caused mortality within 90 days after diagnosis.
