Dogs with brachycephalic conformation frequently suffer from stenotic nares. This study investigated the clinical effects of stenotic nares resection in shih tzu puppies using an amputation technique first described in 1949. The authors hypothesized that surgical correction of the stenotic nares would result in improvement of nasal discharge/noise, breathing difficulty (dyspnea), and exercise limitations (exercise intolerance), and that the technique would provide a cosmetic result. Based on the results of this study, the authors recommend early surgical correction (amputation) of stenotic nares in shih tzu puppies as an effective and cosmetic technique.

Objective: To compare preoperative and postoperative cross-sectional areas (CSAs) of the external nares and nasal vestibule on computed tomography (CT) transverse sections in brachycephalic dogs that underwent a vestibuloplasty in combination with either a Trader's technique or vertical wedge resection rhinoplasty.
Methods: Medical records and corresponding preoperative and postoperative head computed tomographic images were reviewed to measure CSA at two defined points on transverse sections of the nasal cavities.
Results: Nine brachycephalic dogs were included for analysis.

Dogs with a brachycephalic conformation often experience a collection of abnormalities related to their craniofacial conformation, which can lead to a variety of clinical signs such as stertor, exercise intolerance, respiratory distress, and gastrointestinal signs such as regurgitation, among others. This collection of abnormalities is termed brachycephalic obstructive airway syndrome (BOAS). With the rise in popularity of several brachycephalic breeds, veterinarians and veterinary surgery specialists are seeing these dogs with increasing frequency for surgical and medical treatment of these clinical signs, leading to an increased interest in developing surgical techniques for dogs with BOAS and evaluating objective methods of determining outcome after surgery.

Previous studies have shown that the most reliable external conformational risk factor of whether a brachycephalic dog will develop Brachycephalic Obstructive Airway Syndrome (BOAS) is the status of nostril stenosis, assessed as a static observation using the brachycephalic nostril grading scheme. The nostrils however are a dynamic structure, opening further when the dog is exercising, sniffing or panting. The hypothesis of this study was that brachycephalic dogs with open or mildly stenotic nostrils are more likely to have nostril mobility whilst dogs with moderately or severely stenotic nostrils are more likely to have immobile nostrils.

Brachycephalic obstructive airway syndrome (BOAS) comprises a group of anatomical upper respiratory tract abnormalities that collectively result in various degrees of upper respiratory tract obstruction. Stenotic nares is a common feature of BOAS, and in dogs, the main cause is axial deviation of the alar cartilage. In contrast, narrowing of the nares in cats is predominantly the result of a redundant skin fold at the junction of the ventral floor of the nostrils and the haired skin of the lip.

Objective: Surgical correction of stenotic nares, one component of brachycephalic obstructive airway syndrome (BOAS), is not referenced as often in cats as it is in dogs. Similar to dogs, stenotic nares emerge as a significant contributor in the development of BOAS in cats. In this study, we propose that stenotic nares in brachycephalic cats arise from an elongated dorsal lateral nasal cartilage.
