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.
短头畸形阻塞性气道综合征（BOAS）包括一组解剖学上的上呼吸道异常，这些异常共同导致上呼吸道不同程度的阻塞。鼻狭窄是 BOAS 的一个常见特征，在犬中，主要原因是鼻翼软骨的轴向偏斜。相比之下，猫的鼻孔狭窄主要是由于鼻孔底部和唇毛皮肤交界处多余的皮肤皱襞所致。3 只患有吸气性阻塞的短头猫被转诊到伊朗马什哈德费尔多西大学兽医教学医院的外科部门。阻塞的主要原因是由于鼻孔底部有多余的皮肤，导致鼻孔狭窄。所有 3 只猫均采用 Berns 等人（2020 年）首次描述的单蒂推进皮瓣技术进行手术矫正。所有 3 只猫的结果均为阳性，在 9 个月的随访期内，没有手术并发症，也没有出现呼吸窘迫的情况。对患有鼻狭窄的猫进行适当的手术治疗可以获得良好的长期效果。
