Name: UMA Specie: Canino Breed: Labrador Gender: female Years: 10 years y 10 month
Study Done: Laryngo-tracheobronchoscopy
Practice made: placement of laryngeal prosthesis.
Mobility: laryngeal paralysis (this was evaluated with a laryngoscope with the minimum anaesthetic plane in which the inspection was achieved).
Structure: preserved aritenoid cartilage. Exuberant scarring in the vocal cord area (chordectomy performed approximately 1 month and a half ago). Subglottic stenosis.
Tracheobronchoscopy: Slight hyperemia of the tracheal mucosa is observed along its entire length. Carina normal. Extrinsic dorsal compression of the left cranial bronchus compressing approximately 25% of the lumen. With the consent of the family and the referring colleague, a siliconized prosthesis is placed on cords. It is explained that it is an experimental procedure, the possible complications expected to the therapy are explained; the family agrees, understanding the risks. The patient recovers without immediate complications: no stridor is perceived.

Laryngeal paralysis is the inability of the muscles to abduct the arytenoid cartilages during inspiration. In dogs the most frequent presentation is acquired, it is more prevalent in large and giant breeds with an average age of 9-10 years. The etiology usually remains hidden. The traditional treatment is surgical and its objective is to increase the opening of the glottis.
A therapeutic alternative is presented with the placement of a closed siliconized laryngeal prosthesis (stent) in a dog. Presentation of the case: Canine, Siberian Husky, male, 12 years old, presented for consultation at the Hospital Escuela, for episodes of respiratory difficulty in situations of stress or effort and changes in phonation. At the general and particular objective examination, an inspiratory stridor was found as the only abnormality. Laryngeal paralysis was suspected and confirmed by laryngoscopy. At the request of the owners to avoid surgery, an experimental alternative was performed on canines (a technique similar to that used in laryngeal pathologies in humans) by placing a closed silicone prosthesis.
