BOAS Surgery

Brachycephalic Obstructive Airway Surgery

Boas

Brachycephalic Obstructive Airway Syndrome (BOAS) is a serious condition affecting brachycephalic (short-nosed) dog breeds like Pugs, Bulldogs, and French Bulldogs. These breeds have characteristic flattened faces that, while endearing, can lead to significant respiratory challenges. BOAS results from the abnormal anatomy of these breeds, including narrowed nostrils, elongated soft palates, and other structural issues that obstruct airflow.

Understanding BOAS

BOAS is a complex syndrome with multiple contributing factors:

Stenotic Nares: Narrowed nostrils that restrict airflow.
Elongated Soft Palate: The soft palate extends too far back, partially blocking the airway.
Everted Laryngeal Saccules: The tissue within the airway is pulled into the trachea, further obstructing breathing.
Hypoplastic Trachea: A smaller-than-normal trachea that reduces airflow.

What to expect from BOAS surgery?

Nares Widening

Surgical widening of the nostrils to improve airflow.

Soft Palate Resection

Trimming the elongated soft palate to prevent airway obstruction.

Laryngeal Sacculetomy

Removal of everted laryngeal saccules to open the airway.

FAQ

How successful is BOAS Surgery?

Addressing abnormalities related to this syndrome early can lead to better outcomes, as the condition may worsen over time. Correcting a narrow nostril or elongated soft palate can improve airway function and lower the risk of complications like an inverted laryngeal sac. Post-surgery swelling may affect breathing, so your veterinarian will closely monitor recovery, adjusting their level of observation based on the specific procedures performed.

What is the prognosis of a dog suffering with BOAS?

The prognosis for pets with brachycephalic airway syndrome depends on the number of anatomical abnormalities and the age of the dog at diagnosis and treatment. Generally, dogs under two years old at the time of surgery have better outcomes than older dogs. Those needing surgery only for narrow nostrils or an elongated soft palate tend to have a more favorable prognosis compared to those with multiple issues. Dogs with tracheal hypoplasia may have inconsistent prognoses, especially if they have additional problems like allergic airway disease or complications from airway failure. However, effective management can greatly improve their quality of life.
