Abstract

Feline Otitis Externa (OE) is the inflammation of the external ear canal, outside of the tympanic membrane, and sometimes the pinna of a cat. To date, there is a lack of published data regarding the prevalence and outcome of giving empirical therapy solely based on cytological findings of feline OE. The present study aimed to (i) determine the frequency of the primary causes, secondary causes, and microbial association with OE; (ii) determine the types of diagnostic methods and effectiveness of treatments and the outcome of OE. Patient medical records of the affected cats presented to the University Veterinary Hospital (UVH), UPM were reviewed retrospectively from July 2019 to June 2022. Descriptive analyses were performed. From this three-year study, 5704 cats were presented to UVH and a total of 68 cats with 138 visits were diagnosed with OE. The prevalence of feline OE was 1.2%. The majority of the cats were predominantly male (52.9%), 1 to 6 years old (52.9%), Domestic Shorthair (55.9%), from a multi-cat household (51.5%), and fed with a commercial diet (42.7%). The top aetiology and secondary cause of feline OE were both bacterial infections (n=23, 33.8%). Ear swab cytology was performed in at least one ear (n=16, 23.5%). Findings of bacteria (n=16), yeast (n=10) and a mixture of both (n=3) were noticed in all specimens evaluated on cytology. The clinicians primarily conducted bacterial culture and antimicrobial susceptibility testing at the second visit (n=10). Resolved cases (22.1%) took a duration from 10 to 58 days, which is 2 months to recover. Empirical therapy (n=53, 77.9%) was predominantly done. In conclusion, the overall prevalence of feline OE, aetiologies, diagnostic methods and the reportedly low resolved cases identified in this study illustrates the significance of definitive therapy for rapid recovery.
