Otitis externa (OE) is a very common disease of dogs. Various treatments are available for OE, but most commercial preparations contain a mixture of antifungal, anti‐inflammatory drugs and antibiotic agents. The aim of this study was to evaluate if a commercial product containing clotrimazole, marbofloxacin and dexamethasone (Aurizon ® ) was more effective than the use of a topical antifungal agent econazole (Daktarin ® ) used alone to treat Malassezia otitis. Dogs presenting with bilateral OE and numerous yeasts on cytological examination were included. Twenty dogs aged from 1 to 14 years old were treated in this trial (40 ears, 20 in each group). Each case was treated with Aurizon ® (four drops) in one ear and Daktarin ® in the other ear. Criteria analysed were pruritus (visual analogue scale), erythema, amount of cerumen, and the number of yeasts on cytologic smears. All animals demonstrated a good improvement in Malassezia counts after either treatment. Significant differences were noted in favour of Aurizon ® for erythema, cerumen, and pruritus on various days of evaluation. This study demonstrated the superiority of a mixture of corticosteroids and antifungal agent in comparison with an antifungal agent used alone for the treatment of Malassezia OE. Funding: Self‐funded.
