Laryngeal and Tracheal Stents

The word stent refers to material that supports some form of tissue against collapse. Most often, stent describes devices that maintain the lumens of tubular organs. In 1965, Montgomery first described the use of silicone prostheses for tracheal stenting.  

Types of stents include laryngeal stents, tracheal stents, combination tracheal and laryngeal stents, and stents that can be used either in the larynx or trachea.

Occasionally, long-term stenting is needed when the trachea above the tracheotomy tube requires stenting for either collapse or stenosis following reconstruction. In this case, a long stent wired to the trachea or a tracheal tube (T-tube), such as the Montgomery T-tube, can be used.

Aboulker stents, ranging from 15-mm diameter on the left to 3 mm. These stents are hollow and coated in Teflon
