Hi, I'm Dr. Lidija. When we talk about BOAS surgery, we refer to brachycephalic obstructive airway syndrome. This condition mainly affects dogs with short noses or brachycephalic breeds like Boxers , English Bulldogs , French Bulldogs , Pugs, and similar breeds. This means that they often have very narrow nostrils. They have an elongated soft palate and saccules in their larynx. All of this leads to heavy breathing and makes it more difficult for them to get oxygen. What we do during the surgery is make this easier. We open up the nostrils, shorten the soft palate, and, if necessary, correct the larynx. Over a longer period of time, this helps the pet breathe better and significantly lowers the risk of respiratory issues and cardiac problems later in life.
