Laryngeal stent implantation in dogs: step-by-step guide
Updated: Oct 16
A laryngeal stent is placed in dogs through the mouth, with forceps and without a surgical approach. This guide walks veterinary professionals through the technique step by step, from choosing the right stent size to verifying its position.
How to choose the laryngeal stent size
A laryngeal stent of the appropriate size is selected for the dog, taking into account the dimensions of the larynx.
The size of the endotracheal tube that would be used to intubate the patient can be used as a reference.
If you are not sure which size your patient needs, you don't have to bet on a single one. Our Starter Kit includes several sizes, so you can choose the best fit at the time of the procedure.
Laryngeal stent implantation, step by step
1. Stent implantation
The laryngeal stent is inserted through the patient's mouth with the help of forceps. The stent is folded, and then guided into the larynx.
Once in the correct position in the larynx, the stent is released from the forceps and expands, attaching itself naturally to the laryngeal wall. The studs or spurs on the stent help with fixation and perfect placement; two of them must be positioned cranial to the vocal folds.
2. Verification and adjustment
The position of the stent is verified under direct vision from the mouth, by laryngoscopy or X-rays, and adjustments are made if necessary to ensure optimal positioning.
Epiglottis must move freely.
Because ABTVET stents are made of silicone, they can be repositioned as many times as necessary until the veterinarian is satisfied.
Some veterinarians prefer to place a stitch on the side to ensure fixation.
3. Instrument removal
Once the stent is in place, the instruments are removed from the patient's mouth. The whole procedure is done through the mouth, with no surgical incision.
Why choose ABTVET silicone laryngeal stents
Medical-grade silicone, designed for the airway, with more than 20 years of experience behind the brand.
Repositionable: can be moved as many times as needed during placement.
No surgeon required: the stent is placed through the mouth, without a surgical approach.
No specific instruments needed: any long-shafted instrument can be used to place it.
Several sizes in one kit, so you are prepared whatever the patient's anatomy.
Frequently asked questions
Does laryngeal stent placement in dogs require surgery?
No. The stent is inserted through the mouth with forceps, with no surgical incision. Its position is verified by laryngoscopy or X-rays.
Do I need to be a surgeon to place a laryngeal stent?
No. Since the technique is performed through the mouth and does not involve a surgical approach, it does not require a surgeon.
What instruments do I need?
Forceps to fold, clamp and guide the stent. No specific instruments are required: any long-shafted instrument can be used.
Can the stent be repositioned if it is not well placed?
Yes. Because of the silicone it is made of, an ABTVET stent can be moved as many times as necessary until the veterinarian is satisfied with its position.
How do I choose the right stent size?
By taking into account the dimensions of the larynx and/or trachea. The size of the endotracheal tube used to intubate the patient is a useful reference. Having several sizes available, as in our Starter Kit, avoids relying on a single measurement.
Should the stent be sutured?
Some veterinarians place a stitch on each side to ensure fixation, although the studs on the stent already help hold it in place.
