    Area of Science:

    • Veterinary Surgery
    • Experimental Animal Models
    • Surgical Innovation

    Background:

    • Tracheostomy is essential for canine laryngeal experiments but often poorly tolerated due to cannula displacement or blockage.
    • Existing tracheostomy methods in dogs can lead to significant airway complications, risking valuable experimental subjects.
    • A need exists for a more reliable and safe surgical airway technique in research animals.

    Purpose of the Study:

    • To present a new, reversible surgical technique for long-term canine tracheostomy.
    • To establish a dependable and safe airway for experimental animals, minimizing complications.
    • To assess the feasibility and safety of the novel technique in a canine model.

    Main Methods:

    • A new surgical technique for tracheostomy was developed, based on established principles to prevent local tracheal issues.
    • The procedure avoids removal or irreparable damage of essential tissues, ensuring reversibility.
    • Twenty-one dogs underwent the procedure and were monitored for 3- and 6-month periods.

    Main Results:

    • No instances of airway obstruction morbidity were observed in the 21 animals studied.
    • The technique provided a long-term, dependable airway throughout the observation periods.
    • The stoma management offered flexibility, allowing for either maintained patency or gradual closure.

    Conclusions:

    • The novel tracheostomy technique offers a safe and effective solution for establishing a long-term airway in dogs.
    • This method significantly reduces the risk of airway complications, thereby decreasing the loss of experimental animals.
    • The technique shows potential for application in human patients requiring a stable airway.
