Inducible Laryngeal Obstruction in the Paediatric Population – Review of the Literature and Current Understanding

Abstract

nducible laryngeal obstruction (ILO) is a complex entity and its exact mechanisms are still unclear. It is characterised by transiente and reversible narrowing of the larynx in response to external triggers, resulting in symptoms such as cough, dyspnoea and noisy breathing. The prevalence of this condition in adult or paediatric populations is uncertain. Management of ILO starts by establishing an accurate diagnosis, and treatment includes control of trigger factors, breathing and relaxation techniques, and speech and respiratory therapy. The aim of this article is to summarise current understanding and provide a review of the literature of ILO in the paediatric population.
