Nasal septal deviation has been studied in relation to nasal pathology and mass effect in dogs. The purpose of this retrospective, cross-sectional study was to compare the prevalence of nasal septal deviation in dogs with rhinitis, neoplasia, and those without nasal pathology based on the facial index, skull index, and cranial index. Computed tomographic studies of the nasal cavities of dogs performed over a 5-year period were retrospectively reviewed. This study had 233 dogs meeting the inclusion criteria with 135 dogs with no nasal pathology, 63 dogs with nasal neoplasia, and 35 dogs with rhinitis. The prevalence of nasal septal deviation, the angle, maximum distance, and longitudinal extent of deviation were recorded, as well as measurements to calculate the facial index, cranial index, and skull index. The results showed no difference in the prevalence of nasal septal deviation between dogs with nasal pathology and those without. The mean longitudinal extent of deviation and maximum distance of deviation was statistically greater for those with neoplasia compared to those with rhinitis and without nasal pathology. The longitudinal extent of deviation was inversely proportional to the cranial index, facial index, and skull index. The angle of deviation was directly proportional to the facial index and skull index. In conclusion, nasal septal deviation is an anatomic variant in different breeds of dogs with no predilection based on nasal pathology. Nasal septal deviation should be interpreted cautiously in the assessment of canine nasal disease.
已经对犬鼻中隔偏曲与鼻腔病理及占位效应的关系进行了研究。这项回顾性横断面研究的目的是根据面部指数、颅骨指数和头颅指数，比较患有鼻炎、肿瘤以及无鼻腔病理病变的犬鼻中隔偏曲的患病率。对5年期间进行的犬鼻腔计算机断层扫描研究进行了回顾性分析。本研究有233只犬符合纳入标准，其中135只无鼻腔病理病变，63只患有鼻腔肿瘤，35只患有鼻炎。记录了鼻中隔偏曲的患病率、偏曲角度、最大距离和纵向范围，以及计算面部指数、头颅指数和颅骨指数的测量值。结果显示，有鼻腔病理病变的犬和无鼻腔病理病变的犬在鼻中隔偏曲患病率上没有差异。与患有鼻炎和无鼻腔病理病变的犬相比，患有肿瘤的犬的平均偏曲纵向范围和最大偏曲距离在统计学上更大。偏曲纵向范围与头颅指数、面部指数和颅骨指数成反比。偏曲角度与面部指数和颅骨指数成正比。总之，鼻中隔偏曲是不同品种犬的一种解剖变异，不基于鼻腔病理情况而有偏好。在评估犬鼻腔疾病时，应谨慎解读鼻中隔偏曲。
