Abstract

This study was performed to determine a comprehensive anatomic variation and deviation of the nasal septum in clinically normal dogs by use of computed tomography (CT). The nasal septum was evaluated in 36 shihtzu dogs and 16 beagle dogs. A degree of a septal deviation was evaluated by measuring a maximum angle and a distance of the septal deviation. The angle and distance of the septal deviation were significantly higher in shih-tzu dogs than in beagle dogs. There was no significant relationship between body weight and age and all measurements (angle and distance) in both breed dogs. Results of this study suggest that nasal septum deviation and its defect are observed on CT images of clinically normal dogs, especially in shih-tzu dogs.

본 실험은 임상적으로 건강한 시츄 견 36 두, 비글 견 16 두에서 컴퓨터단층촬영을 이용하여 비중격의 해부학적 차이와 편위 정도를 평가하고자 실시되었다. 비중격의 편위 정도는 비중격 편위의 각도 및 거리 측정에 의해 평가되었다. 비중격 편위의 각도 및 거리는 비글 견보다 시쮸 견에서 유의적으로 높은 수치를 나타냈다. 시츄, 비글견 두 품종에서 체중 및 나이는 비중격 편위의 각도 및 거리와 모두 유의적인 관계는 관찰되지 않았다. 이 결과에 기초하여 비중격의 편위는 임상적으로 건강한 개에서도 관찰 가능하며, 특히 시츄 견에서 쉽게 관찰되는 것으로 생각된다.
