What is brachycephalic obstructive airways syndrome?
Brachycephalic breeds have stenotic (narrow) nares (nostrils) and nasal passages. This results in increased resistance to airflow through the nares and nasal passages resulting in an increased effort to breathe. This increased negative pressure in the back of the throat in turn results in stretching of the soft palate. The skull of brachycephalic dogs can grow to be very long and narrow. The muzzle is also smaller than in non-brachycephalic breeds. The short muzzles and narrowed nostrils lead to breathing difficulties. The soft palate can also be affected by the deformity of the skull.A brachycephalic skull is flat in the rear. The crown of the head towards the back is often high, the baby’s face may be wide and the ears can also protrude. Sometimes brachycephaly is a congenital condition, which means it exists at or before birth.What does brachycephalic mean? Brachy means shortened and cephalic means head. Therefore, brachycephalic dogs have skull bones that are shortened in length, giving the face and nose a pushed-in appearance.Dolichocephalic have extremely long skulls with long and slender noses. Examples include Greyhounds, Dachshunds, Great Danes, etc. Brachycephalic are short nosed, flat faced breeds whose skulls are broad. Examples include Pugs, Boxers, Bulldogs, etc.
What are the 4 components of brachycephalic airway syndrome?
The primary anatomic components of BAS include stenotic nares and elongated soft palate, though other commonly recognized components include tracheal hypoplasia and nasopharyngeal turbinates. Stenotic nares surgery — Stenotic nares can be treated by removing a tissue wedge from your pug’s nostrils, allowing improved airflow. Elongated soft palate surgery — An elongated soft palate can be surgically shortened to a more normal length.Moderate to severe cases are corrected with a relatively simple surgical procedure. Read more about Pug Dog Stenotic Nares. This involves the soft palate, which is located at the back of the throat, partially blocking the entrance to the trachea, making it difficult to breathe well.Surgical treatments are aimed at relieving the upper airway obstruction through widening of the stenotic nares, shortening of the soft palate, and removal of everted laryngeal saccules. There are numerous techniques described for both widening the nares and treating the elongated palate.Accepted primary components of brachycephalic obstructive airway syndrome include stenotic nares, elongated soft palate, hypoplastic trachea, aberrant nasal turbinates, and macroglossia.The goal of surgery for animals with brachycephalic airway syndrome is an overall reduction in airway resistance so correction of stenotic nares is usually part of a package of surgeries directed to this purpose. Surgical correction entails removal of a wedge of the alar wing lateral to the naris to increase airflow.
What is the surgery for brachycephalic syndrome?
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. Uvulopalatopharyngoplasty is a procedure to remove the uvula, tonsils, and parts of the soft palate. Doctors use small surgical instruments to excise the tissues blocking the airway, increasing its size and thereby improving airflow and reducing apnea episodes.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.
How to treat brachycephalic airway syndrome?
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. 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.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 to expect after BOAS surgery: Most dogs will have noticeably quieter breathing sounds straight away, with swelling gradually improving over the following 2 weeks after surgery. There may be a small amount of blood around the nostrils and mouth for the first 24h.
What is an example of brachycephalic?
In pets, brachycephaly describes a type of skull with a high cephalic index, such as in snub-nosed breeds of dog such as pugs, Shih Tzus, and bulldogs or cats such as the Persian, Exotic and Himalayan. The term is from Greek roots meaning ‘short’ and ‘head’. Brachycephalic dog breeds, like Boston terriers, boxers, and pugs, have ‘squished faces’ or shortened snouts, which increases their risk of developing breathing problems. Pet owners should closely monitor these breeds for signs of increased respiratory effort.The technical term for breeds like pugs, French bulldogs (“Frenchies”), Boxers, Cavalier King Charles spaniels, Shih Tzus and others is “brachycephalic. The structure of their bodies means that these breeds often suffer from health problems like breathing issues, skin fold infections, eye issues, back and joint issues .Brachycephalic breeds are particularly prone to airway obstruction during the perianesthetic period. They are prone to obstruct and die if left unattended after having been given sedatives or anesthetic drugs.

The structure of their bodies means that these breeds often suffer from health problems like breathing issues, skin fold infections, eye issues, back and joint issues . Brachycephalic means shortened head. There are lots of pets selected for this appearance and have short snouts and flat faces. Flat-faced animals include: Pugs.
