Laryngeal web

What it means

A membrane-like structure that extends across the laryngeal lumen close to the level of the vocal cords.

Manifestations may appear at any age (hoarse or weak voice and frequent upper respiratory infections) but onset usually occurs during infancy (respiratory distress, stridor and an unusual cry).

The range is how often this sign appears among people diagnosed with each disease — it is not a probability of having any of them. Many of these signs also occur in common, non-rare conditions. A sign on this page is a conversation to have with a clinician, not a conclusion.
