Brachycephalic Obstructive Airway Syndrome – Treatment
Elongated soft palate
Shortened soft palate
The mainstay of treatment for BOAS remains surgical, however some medical measures can also be taken. When considering medical management, it is important to focus on factors that can cause worsening of the signs, such as weight loss and allergies. Other factors to consider are housing the patient in a cool environment, avoiding the use of neck leads, decreased activity levels and the use of gastroprotectants for any concurrent vomiting or regurgitation. Typically medical management is used after (and in conjunction with) surgical management.
There are many questions that arise when considering surgical management and one of the biggest is when do you consider surgery? BOAS can be seen even in puppies and it is recommended that an evaluation be performed in dogs that are predisposed to this condition. Early management can halt or delay the progression that is typically seen, especially laryngeal collapse.
There are various methods to widen the nares(nostrils). The most common technique is the vertical wedge resection, where a wedge of tissue is removed with the apex of the triangle at the dorsal surface. An absorbable suture can be placed to control bleeding. It is important to make sure that the nares is wide enough to increase airflow.
An elongated soft palate is one of the most common features of BOAS. The assessment and skilled resection is key. If too much is removed, then there is a communication between the oropharynx and nasopharynx. If not enough is removed then the problem still exists. The most common technique employed is resection with metzenbaum scissors and suture. Sharp excision of the soft palate generally ensures the least amount of inflammation. Other methods, such as CO2 laser and Ligasure, have been described and can be successful. Complications that can arise are as follows: bleeding, inflammation, chronic granulation tissue formation, and further elongation of the soft palate over time.
As mentioned previously, the presence of everted saccules characterizes the patient with stage I laryngeal collapse. There is some controversy as to whether or not everted saccules should be addressed surgically.
With patients that have grade II and III laryngeal collapse surgical correction is more difficult. When collapse is present it is always recommend to correct what is correctable, however the larynx will never be functional again. Some propose modified laryngeal tieback procedures with mixed outcomes. A permanent tracheostomy becomes a very viable option. By performing a permanent tracheostomy the entire upper airway is by-passed.
When counseling owners, generally dogs affected with BOAS have a favorable prognosis. Success is solely dependent on progression of disease. Education of owners should start when the patient is a puppy to avoid worsening. When a patient progresses to laryngeal collapse prognosis decreases greatly, as well as hospitalization time.

Brachycephalic Upper Airway Syndrome (BUAS) – diagnosis
Diagnostic testing:
In addition to direct visualization of structures it is wise to evaluate both the neck and chest. This is most commonly performed with radiographs (X-rays). Structures to evaluate include the oro/nasopharynx, trachea, lungs (for pneumonia, etc), and cardiac disease. If cardiac disease is suspected due to auscultation and radiographs, an echocardiogram is recommended. A complete blood count (CBC), chemistry and urinalysis should be performed prior to anesthesia to assess total body function and if your pet is a good anesthetic and surgical candidate.
A very important part of the diagnostic workup performed just before surgery is the oral examination. One way to evaluate the upper airway is endoscopy of both the larynx and esophagus. This will provide a very thorough evaluation of the soft palate, ventricles and laryngeal function.
Direct visualization is the most common way of diagnosing the associated factors of the brachycephalic dog. The nares are narrower than a normal dog and the airflow is distorted. For a sedated oral exam, the patient is typically anesthetized (light plane of anesthesia). Evaluating the laryngeal function in these dogs is very important in differentiating laryngeal paralysis from laryngeal collapse.
The mainstay of treatment for BUAS remains surgical, however some medical measures can also be taken. When considering medical management, it is important to focus on factors that can cause worsening of the signs, such as weight loss and allergies. Other factors to consider are housing the patient in a cool environment, avoiding the use of neck leads, decreased activity levels and the use of gastroprotectants for any concurrent vomiting or regurgitation.

This is such a touching story, so I choose to share this as it is animal related. It really demonstrates the bond that we have with our pets and how much influence they really have!!
Brachycephalic Upper Airway Syndrome (BUAS) – physical exam
Most commonly the history of patients with BUAS are very similar. Generally, owners notice snoring and gradual progression of inspiratory stridor. Many times this will occur while the patient is a puppy and continue into adulthood. Other signs that are noted are increasing frequency of dyspnea especially during exercise or a hot environment. Another sign to look for in addition to the other is vomiting and/or regurgitation. This can be a compounding problem as it predisposes the pet to aspiration pneumonia.
On physical exam one of the first things that can be directly visualized is the nares being stenotic. The observant examiner will also note an increased upper respiratory noise with inspiratory stridor on auscultation(listening with a stethoscope. Typically the rest of the general physical examination is within normal limits.
Prior to performing a sedated oral exam various differentials should be on the list and should include neoplasia (oral/pharyngeal masses/cancer), tracheal collapse, laryngeal paralysis, lower airway disease and cardiac(heart)disease. Both lower airway diseases and cardiac disease can greatly exacerbate upper airway signs and if the patient is stable, these should be addressed first or at least concurrently.
Our next segment will be an overview of the surgical treatment and then we can wrap up this topic.
