Dilatation (Dilation)

Dilatation, or dilation, is to stretch an opening to a larger size. When an individual has stenosis of the laryngeal airway or the trachea, a dilation procedure is one option for treatment. The two primary methods of dilation in these cases are to use either a balloon expansion device or successively larger tapered laryngeal dilators. With tracheal stenosis, a balloon expansion device might be used more often, but for high tracheal stenosis, the tapered laryngeal dilators can also be very effective.
