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. Three brachycephalic cats with inspiratory obstruction were referred to the surgery department of the Veterinary Teaching Hospital of Ferdowsi University of Mashhad, Iran. The predominant cause of obstruction was nostril stenosis due to the presence of redundant skin on the ventral floor of the nares. All three cats underwent surgical correction using a single pedicle advancement flap technique, which was first described by Berns et al. (2020). All three cats had positive outcomes, with no surgical complications and no episodes of respiratory distress reported within a 9-month follow-up. Appropriate surgical treatment of feline patients with stenotic nares can result in good long-term outcomes.
