A 20-month-old, intact male shih tzu was evaluated for chronic upper airway disease. Endoscopic examination established a diagnosis of choanal atresia, a developmental anomaly of the posterior nasal cavity. Although surgical intervention provided temporary relief, stenosis of the nasopharynx by obstructive scar tissue was confirmed within four weeks. A permanent tracheostomy provided long-term relief of the respiratory difficulty. This is the first report of choanal atresia or nasopharyngeal stenosis in a dog.
一只20个月大、未绝育的雄性西施犬因慢性上呼吸道疾病接受评估。内镜检查确诊为后鼻孔闭锁，这是一种后鼻腔的发育异常。尽管手术干预提供了暂时的缓解，但四周内证实阻塞性瘢痕组织导致了鼻咽部狭窄。永久性气管切开术为呼吸困难提供了长期缓解。这是犬类后鼻孔闭锁或鼻咽部狭窄的首例报告。
