CUESTAS, Giselle  e  RODRIGUEZ, Hugo. Algorithm for the management of laryngeal obstruction in pediatrics. Arch. argent. pediatr. [online]. 2022, vol.120, n.3, pp.18-18.  Epub 01-Jun-2022. ISSN 0325-0075.  http://dx.doi.org/10.5546/aap.2022.209.

The larynx is at the aerodigestive crossroads; any pathology that involves it will have an impact on breathing, swallowing and/or the voice. It's divided into three regions: supraglottis (includes epiglottis, ventricular bands and laryngeal ventricles), glottis (space limited by the vocal cords) and subglottis (narrowest area of pediatric airway and the only point of larynx completely surrounded by cartilage: the cricoid ring). Laryngeal obstruction can present as a potentially fatal acute condition or as a chronic process. The main symptom is inspiratory or biphasic stridor. The etiology varies widely according to age and it may be of congenital, inflammatory, infectious, traumatic, neoplastic or iatrogenic origin.

We describe the pathologies that cause laryngeal obstruction, either those that occur very often or those which are important for their severity, their guiding symptoms to the presumptive diagnosis, additional studies and treatment.
