ICD-11 CA0H.4 — Laryngeal spasm

Laryngeal spasm is a pathological condition that is mainly a spasmodic closure (spasm) of the inlet portion of the larynx or the glottic region. There is an adult-onset and childhood (infant)-onset generally in this disease. There is a difference in the pattern of expression for these two types. In the infant, respiratory arrest is associated with this condition and spasmodic closure of the glottis occurs suddenly, and then breathing returns to original quite rapidly within a few minutes. In adults, the main symptoms of this condition are difficulty breathing or inspiratory stridor rather than a complete respiratory arrest.

The diagnosis excludes nothing.
