Laryngeal Stent

Code LP/LM/LG

The Laryngeal Stent —also called laryngeal mold or laryngeal prosthesis— is a silicone prosthesis that copies the relief of the endolarynx. This flexible mold is an alternative to support the laryngeal framework in situations of organ trauma or after reconstructive surgery.

It has a very smooth surface and blunt edges that reduce trauma to the mucosa. Its flexibility favors tolerance, and its solid configuration prevents collapse and deformation. The Laryngeal Stent is radiopaque and comes with two curved silicone discs for external fixation.

Implantation technique

The implantation of a laryngeal stent requires a prior tracheostomy, since oronasal breathing will not be possible.

The surgical procedure will be chosen by the treating physician, but in cases of stenosis an anterior and posterior laryngofissure with a costal cartilage graft is usually performed to achieve greater laryngeal stability. Once the stent is in the proper position, it can be fixed with two retention sutures running skin–subcutaneous tissue–stent–soft tissue–skin, and it will remain as a stent-tutor for as long as the physician deems necessary in each case. Removal is performed through the oral route, withdrawing it with forceps that grasp it by its upper end.

Post-implantation care

No additional care is required beyond the postoperative care of the laryngeal surgery.

Warning for use

Important

The device must not be reused, as this could cause cross-contamination.
