Airway Surgery BOAS and Laryngeal Paralysis
Upper airway surgeries in dogs primarily address structural obstructions that impede normal breathing. These procedures are most common in brachycephalic (flat-faced) breeds and older large-breed dogs.
It is commonly recommended for pets with labored breathing, exercise intolerance, or airway-related distress.
Our goal is to improve airflow, reduce respiratory effort, and enhance overall quality of life.
BOAS Surgery Overview
Brachycephalic Obstructive Airway Syndrome (BOAS) is a collection of anatomical abnormalities. Most dogs require a “multi-level” approach, performing several of these procedures at once.
Stenotic Nares (Nostril Widening)
A wedge of tissue is removed from the nostrils to enlarge the openings and reduce airway resistance.
Elongated Soft Palate Resection (Staphylectomy)
The overhanging portion of the soft palate is shortened so it no longer vibrates or blocks the laryngeal opening.
Everted Laryngeal Saccule Resection
Small sacs in the larynx that have been pulled into the airway by increased breathing effort are removed to clear the passage.
Expected Outcome
Dramatic improvement in breathing, reduced snoring, and better heat tolerance. While breathing may never be 100% “normal,” roughly 90-94% of owners report a high degree of satisfaction with the clinical improvement.
Unilateral Arytenoid Lateralization
Unilateral Arytenoid Lateralization (“Laryngeal Tie-Back”) is used primarily to treat Laryngeal Paralysis, a condition where the cartilages that open the airway fail to move.
The Procedure
A permanent suture is used to “tie back” one side of the larynx into a fixed open position, allowing air to flow freely into the trachea.
Expected Outcome
Immediate and significant relief from respiratory distress. Most dogs return to a good quality of life for 1–2 years after surgery.
Lifelong Consideration
Because one side of the airway is permanently open, there is a lifetime risk of aspiration pneumonia (approx. 8–21%). Owners must use elevated bowls and avoid swimming.
Recovery & Aftercare
Monitoring
Most patients are monitored in-hospital for 8–24 hours post-op to manage potential swelling in the throat.
Activity
Strict rest for 10–14 days (BOAS) to 4–6 weeks (Tie-back) to allow surgical sites to heal.
Equipment
Pets should switch permanently from neck collars to harnesses to avoid putting any pressure on the surgical sites or airway.
