To determine whether endoscopic examination of the choanae resulted in diagnosis of various diseases in dogs and cats with signs of respiratory tract disease.
Retrospective study.
91 dogs and 27 cats that had endoscopic examination of the choanae.
Medical records were reviewed for endoscopy findings and results of examination of biopsy or cytologic specimens.
34 animals had neoplasia in the choanal region; in 26 animals, diagnosis was confirmed by evaluation of specimens obtained by endoscopy. Five dogs with neoplasia had an erroneous diagnosis of rhinitis made on the basis of evaluation of specimens obtained by endoscopy. Six dogs and 2 cats had foreign objects in the choanae; 7 foreign objects were removed endoscopically, whereas 1 required nasal flushing. Results of endoscopy and biopsy of the choanae provided diagnosis of cryptococcosis and aspergillosis, but did not aid in the diagnosis of pythiosis or nasal mites.
Endoscopic examination of the choanae may assist in rapid diagnosis of nasal neoplasms, foreign objects, and certain infectious organisms.
确定对患有呼吸道疾病体征的犬猫进行后鼻孔内镜检查是否能诊断出各种疾病。
回顾性研究。
91只犬和27只猫接受了后鼻孔内镜检查。
查阅病历以获取内镜检查结果以及活检或细胞学标本的检查结果。
34只动物在后鼻孔区域发生肿瘤；26只动物通过对内镜获取的标本进行评估确诊。5只患有肿瘤的犬基于内镜获取标本的评估被误诊为鼻炎。6只犬和2只猫的后鼻孔有异物；7个异物通过内镜取出，而1个需要鼻腔冲洗。后鼻孔内镜检查和活检结果可诊断隐球菌病和曲霉病，但对诊断芽生菌病或鼻螨没有帮助。
后鼻孔内镜检查可能有助于快速诊断鼻腔肿瘤、异物和某些感染性生物体。
