Otitis externa is an inflammatory disease of the external ear canal; a therapeutic alternative is the controlled-flux electrolyzed acidic solution (SAEFC) with bactericidal and bacteriostatic properties. The purpose of this study was to evaluate the clinical and cytological efficacies of SAEFCin otitis externa. A total of ۳۰ dogs were examined. The clinical and cytological evaluations were on days ۱, ۷ and ۱۴; the following was considered: Pain, erythema, exudate, inflammation, ulcers, putrid odor and pigmentation. Cytological evaluations were carried out to examine the presence of polymorphonuclear leukocytes (PMN), intra-cellular bacteria (cocci; IC), extra-cellular bacteria (EC) and yeasts on days ۱, ۷ and ۱۴. A cotton swab saturated with SAEFC was applied for each dog’s ear. The values of PMN diminished having a significant difference between days. The presence of IC (cocci) had a difference in evaluations from day ۱ to day ۷ and from day ۷ to day ۱۴ demonstrating an important drop. The evaluation of pain showed a sustained decrease until reaching ۹۵.۰۰% of remission, erythema diminished ۶۸.۳۳%, the exudate dropped to ۹۰.۰۰%, inflammation was no longer present by day ۱۴ in ۷۸.۰۰% of the cases and ۲۱.۶۷% showed a slight inflammation, the putrid odor dropped to ۹۵.۰۰% and ۵.۰۰% presented a mild odor and by day ۱۴ ear pigmentation was no longer present in ۵۱.۶۷% of the cases and the ۴۸.۳۳% had slight pigmentation. The use of SAEFC is an effective alternative treatment in dogs with otitis externa.
