What causes brachycephalic airway syndrome?

In brachycephalic dogs, like Pugs or Bulldogs, they have a particular breathing challenge. Their noses are kinda squished, which leads to something called stenotic nares. Basically, their nostrils are too narrow, making it harder for them to breathe properly. On top of that, these adorable pups often have elongated soft palates, which are those dangly bits at the back of their mouths. This combination means they have to work extra hard just to get air in and out of their lungs.

But here’s where it gets even trickier. Because these poor pups have to put in so much effort to breathe, their little saccules get all messed up. Saccules are like small pockets in the dog’s larynx, and when they get turned inside out, they create an additional blockage in the airway. So, not only are these brachycephalic dogs struggling due to their narrow nostrils and elongated palates, now they’ve got these flipped-over saccules causing even more trouble for their breathing.

In a nutshell, brachycephalic dogs face some serious breathing issues. Their stenotic nares and elongated soft palates make it extra tough for them to take in the air they need. And if that wasn’t enough, their saccules also get turned inside out, further blocking their airway. It’s a double whammy for these adorable, squished-face fur babies, making it essential for their owners to be aware of these challenges and seek proper care and treatment to ensure their pups can breathe comfortably and happily.

What causes brachycephalic airway syndrome?

In brachycephalic dogs, there is an increased effort to breathe due to the stenotic nares and elongated soft palate. This increased effort to breathe can cause the saccules to turn inside out and further block the airway.

What are the four components of brachycephalic syndrome?

There are main four components of brachycephalic syndrome; two primary and two secondary. The primary components are stenotic nares and elongated soft palate. Secondary components, everted laryngeal saccules and laryngeal collapse, arise as a result of chronic obstructive breathing against the primary components.

How is brachycephalic syndrome treated?

As with most conditions affecting dogs, the sooner they are diagnosed, the sooner they can be treated, which usually results in a better prognosis. With brachycephalic airway syndrome, the most common form of treatment is surgery to correct the abnormality and improve the airflow and breathing abilities of the dog.

What are the clinical signs of brachycephalic obstructive airway syndrome?

Most dogs with this syndrome breathe more easily through their mouths than their noses. The more abnormalities present, the more severe the signs. Mildly affected dogs will have noisy breathing, especially with exercise, and most will snort when excited and snore when relaxed or asleep.

Can brachycephalic be cured?

While there is no cure for Brachycephalic Syndrome, its symptoms can be easily managed. The most important thing is to recognize severe symptoms early and have them corrected, if necessary. Surgical intervention is best at a young age to prevent progression of these problems.

What is the treatment for BOAS?

BOAS is not curable. Nevertheless, upper airway corrective surgery can provide a better quality of life. Regular post-operative rechecks are suggested. Revision surgery might be required in some severely affected dogs.

What is the surgery for brachycephalic airway syndrome?

Surgery involves removing the excess tissue that is present causing the obstruction in the airway and typically includes the following: nares resection (widening of the nostrils), palatoplasty (shortening and thinning the soft palate) and sacculectomy (removing the saccules or “balloon” structures that are in the back …

What are the risks of brachycephalic?

• Breathing problems. Brachycephalic obstructive airway syndrome (BOAS) – also known as brachycephalic syndrome – is common in flat-faced dogs. …
• Heart problems. …
• Tooth problems. …
• Skin and ear problems.

What is an example of brachycephalic?

In addition to those noted above, brachycephalic breeds include: Affenpinscher, Brussels Griffon, Dogue de Bordeaux, Japanese Chin, Lhasa Apso, Brasileiro, and Pekingese.

What age does brachycephalic syndrome occur?

The average age of presentation for brachycephalic syndrome is 4 years, though English bulldogs are often presented earlier in life. Clinical signs typically include stertor, exercise intolerance, heat intolerance, and dyspnea. In more severe cases owners may report cyanosis and collapsing episodes.

How much does brachycephalic airway surgery cost?

The cost of brachycephalic syndrome depends on the severity of the disease and the measures undertaken to relieve the obstructions within these animals’ airways: Soft palate resection: $500 to $1,500. Stenotic nares resection: $200 to $1,000.

What is the surgery for brachycephaly?

Surgery usually consists of procedures to widen the nostrils (resection rhinoplasty), to reduce the length and thickness of the soft palate (partial staphylectomy) as well as surgery to remove the excess laryngeal mucosa. These procedures allow increased airflow and improve how an individual patient breathes.

What age is best for BOAS surgery?

Once the laryngeal cartilages have collapsed for an extended period of time it is very difficult to reverse the damage. It is therefore important that dogs are checked at an early age so surgery can be carried out before further damage is caused, this is usually at 1-2 years of age.

How successful is BOAS surgery?

How successful should I expect surgery to be? Published studies suggest that most dogs show around 50% improvement in their breathing and an 90% improvement in regurgitation after the above surgery. This would hopefully reduce grade 3 dogs to a grade 2 and grade 2 dogs to a grade 1.

What are three signs of airway obstruction?

• Choking or gagging.
• Sudden violent coughing.
• Vomiting.
• Noisy breathing or wheezing.
• Struggling to breathe.
• Turning blue.

What is BOAS caused by?

BOAS is the result of multiple factors acting together to cause obstruction to air flow into the lungs. Primary factors (present from a very young age and related to the head shape): Stenotic nares (narrow nostrils) Aberrant nasal turbinates.

What is the risk of brachycephalic?

Brachycephalic dogs have decreased capacity for thermoregulation compared with non-brachycephalic dogs. Brachycephalic dogs have lower oxygen saturation levels in the blood than non-brachycephalic dogs. Clinical signs due to upper respiratory disorders were noted in 22% of dogs with extreme brachycephalic conformation.

Where did brachycephalic come from?

The term brachycephaly is derived from the Greek words brakhu (short) and cephalos (head), which translates to short head. Brachycephaly is an infant skull deformity characterized by a lower-than-normal ratio of the skull’s length to its width.
