Stenosis of larynx
What is it?
Subglottic stenosis refers to a narrowing of the part of the voice box below the vocal cords. Typically, we are born with 4 mm diameter subglottis, and if it’s under 3.5mm it is considered to be narrowed. Congenital subglottic stenosis is when a baby is born with this narrowing due to an incomplete formation of it before birth. Acquired subglottic stenosis happens due to trauma, infection, or intubation that may scar the tissue and cause narrowed airway.
