The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on Endoscopic balloon dilatation for subglottic or tracheal stenosis.


Subglottic or tracheal stenosis is a narrowing of the windpipe between the throat and the lungs, which can cause wheezing, hoarseness and shortness of breath. It most commonly occurs after a person has needed to use a ventilator (breathing machine) and has had a tube down their windpipe for some time. In this procedure, a small balloon is introduced into the narrowed windpipe through an endoscope (a flexible telescope), which is inserted down the throat. The balloon is then gently inflated to widen the narrowed windpipe.
