SCIENTIFIC_REVIEW Evaluation of video-otoscopic, radiographic and computed tomographic examinations of cats and dogs with ear diseases The aim of this study was to evaluate the effectiveness of imaging techniques (video-otoscopy-VO, radiography-RTG, computed tomography-CT) in diagnosing ear diseases in cats and dogs. Seven cats and thirteen dogs diagnosed with ear diseases were used for the research. Clinical examination, VO, RTG and CT were performed. Three (42.9%) unilateral otitis externa (OE), three (42.9%) unilateral otitis media (OM), and one (14.2%) bilateral otitis media (OM) with OE were diagnosed in 7 cats. Five (38.4%) unilateral OE, one (7.7%) unilateral OM, four (30.8%) bilateral OE, and three (23.1%) bilateral OM with OE were diagnosed in 13 dogs. All diagnostic methods were determined to be highly efficient for the specified diagnosis. VO and RTG were confirmed as sufficiently effective for the diagnosis of OE. OE plays a major role in the etiopathogenesis of OM, and for this reason, RTG and CT are required diagnostic methods for this condition. https://macvetrev.mk/Files/Article/2021/10.2478/macvetrev-2021-0013/macvetrev-2021-0013.pdf 2021-03-15T09:00:00 95 101 10.2478/macvetrev-2021-0013 diagnostic imaging ear diseases cat dog Kurtulus Parlak kparlak@selcuk.edu.tr false 1 Department of Surgery, Faculty of Veterinary Medicine, Selcuk University, 4225 Konya, Turkey LEAD_AUTHOR Mustafa Yalcin false 2 Department of Surgery, Faculty of Veterinary Medicine, Cumhuriyet University, 58140 Sivas, Turkey AUTHOR Hanifi Erol false 3 Department of Surgery, Faculty of Veterinary Medicine, Erciyes University, 38250 Kayseri, Turkey AUTHOR Eyüp Tolga Akyol false 4 Department of Surgery, Faculty of Veterinary Medicine, Balikesir University, 10145 Balikesir, Turkey AUTHOR Elgin Orcum Uzunlu false 5 Department of Surgery, Faculty of Veterinary Medicine, Selcuk University, 4225 Konya, Turkey AUTHOR Nuriza Zamirbekova false 6 Department of Surgery, Faculty of Veterinary Medicine, Selcuk University, 4225 Konya, Turkey AUTHOR Mustafa Arican false 7 Department of Surgery, Faculty of Veterinary Medicine, Selcuk University, 4225 Konya, Turkey AUTHOR Hill, P.B., Lo, A., Eden, C.A.
