Objective- One of the important causes of nasal fracture is a trauma that can be diagnosed in clinical examinations and diagnostic imaging but it should be noted that radiography may show false fractures in the nose. This study evaluates the value of ultrasonography in the diagnosis of nasal fractures and compared it with plain radiography.Design- Retrospective study.Animals- ۱۲ dog patients with suspected nasal fracture.Procedure- These dogs were evaluated by ultrasonography and radiography in comparison with the clinical examination (golden standard) and the results were analyzed by statistical method. Sensitivity, specificity, positive and negative predictive values, positive and negative odds ratio, and accuracy with ۹۵% confidence intervals and the accuracy of both tests were calculated.Results- In the diagnosis of nasal fracture by ultrasonography, sensitivity was ۹۶.۴%, specificity of ۹۳.۳% and accuracy of ۹۶% and in the radiographic method, sensitivity was ۸۱.۱%, specificity of ۸۶.۷% and accuracy of ۸۲%. In ultrasonography and radiography, the most sensitivity in diagnosis of nasal bridge fracture was ۱۰۰% and ۹۲.۶% and the most specificity in diagnosis of the outer wall nasal fracture was ۱۰۰% and ۵۰%, respectively.Conclusion and Clinical Relevance- According to the results of this study, ultrasonography can be used as a non-invasive method with high sensitivity and specificity in the diagnosis of nasal bone fractures in dogs.
