BOAS
BOAS (Brachycephalic Obstructive Airway Syndrome) surgery is a type of surgery performed on brachycephalic (short-nosed) dog breeds to address breathing difficulties and airway obstructions. Brachycephalic breeds, such as Bulldogs, Pugs, French Bulldogs, and Boston Terriers, have characteristic flat faces and shortened airways, which can lead to respiratory challenges.
BOAS surgery aims to improve the airflow through the upper respiratory tract by addressing anatomical abnormalities commonly found in these breeds. Some common features contributing to BOAS include stenotic nares (narrow nostrils), an elongated soft palate, and an everted laryngeal saccule. These abnormalities can lead to breathing difficulties, snoring, and exercise intolerance in affected dogs.
The surgical procedures involved in BOAS surgery may include:
Nasal Stenoplasty: This involves widening the nostrils (nares) to improve the intake of air. The surgeon may remove a wedge of tissue from each nostril to open up the nasal passages.
Soft Palate Resection: The soft palate, which extends into the throat, can be too long in brachycephalic breeds, partially obstructing the airway. Surgery may involve trimming and reshaping the soft palate to reduce obstruction.
Laryngeal Saccule Resection: If the laryngeal saccules (small structures in the larynx) are everted and causing airflow obstruction, they may be removed or modified to alleviate the breathing difficulty.
Tonsillectomy: In some cases, removal of the tonsils may be considered as part of the overall treatment plan. The tonsils are clusters of lymphoid tissue located at the back of the throat, and they can contribute to airway obstruction in brachycephalic breeds.
BOAS surgery is considered when conservative management, such as weight management and environmental modifications, does not sufficiently improve the dog's respiratory function. The decision to pursue surgery is typically based on the severity of the clinical signs, the dog's overall health, and the owner's commitment to post-operative care.It's important for pet owners to work closely with veterinarians and veterinary surgeons specializing in brachycephalic breeds to assess the specific needs of their pets and to understand the potential risks and benefits of BOAS surgery. Post-operative care, including monitoring and lifestyle modifications, is crucial for the long-term well-being of dogs undergoing BOAS surgery.
