Resumo
A otite canina é uma patologia que apresenta uma etiologia multifatorial, pelo que o seu diagnóstico deve ser o mais completo e preciso possível. Os principais sinais clínicos podem ser identificados, precocemente, pelos tutores. Estes afirmam que viram o seu animal a abanar a cabeça e/ ou as orelhas e a coçar a região peri-auricular, correspondendo à presença de sinais como inflamação (edema), eritema, desconforto/ dor, otorreia ou secreções com odor fétido. O tratamento convencional é administrado de forma empírica recorrendo a soluções tópicas compostas por corticosteroides, antibióticos e antifúngicos. Nos últimos anos, o aumento da resistência bacteriana tornou-se cada vez mais um problema para a saúde a nível global e isto levou à necessidade de procurar outras alternativas terapêuticas que pudessem ser utilizadas como substituto aos fármacos antimicrobianos, que fossem iguais ou mais eficazes. Esta dissertação foi realizada no âmbito da conclusão do Mestrado Integrado em Medicina Veterinária da Universidade Lusófona e pretendeu-se com este trabalho avaliar e comparar a eficácia entre o tratamento integrativo, com solução tópica auricular comercial de óleo de ozono, e o tratamento convencional, com uma solução tópica auricular comercial composta por corticosteroide, antifúngico e antibiótico, aceites eticamente e realizados em diversos CAMVs, para a resolução de otite por Malassezia pachydermatis em cães. Para tal, através de uma amostra de 30 indivíduos, perfazendo um total de 60 orelhas em estudo, foram formados dois grupos cada um composto por 15 animais. O grupo A foi submetido ao tratamento otológico convencional e o grupo B foi submetido ao tratamento otológico integrativo com ozonoterapia. Todos os animais foram avaliados, tendo em conta a presença de sinais clínicos e citologia auricular, nos dias 0, 7 e 14 de tratamento de forma perceber a sua evolução. Foi demonstrado que o tratamento integrativo com ozonoterapia usado neste trabalho foi mais eficaz em comparação com o tratamento convencional nas otites por Malassezia pachydermatis após 14 dias de tratamento, provando ser uma alternativa segura devido ao facto de, até agora, nenhuma resistência bacteriana ao ozono ter ocorrido.

Canine otitis is a pathology that has a multifactorial etiology, so its diagnosis should be as complete and accurate as possible. The main clinical signs can be identified early by the owners. They claim that their animal is shaking its head and/or ears and scratching the peri-auricular region, corresponding to the presence of signs as inflammation (edema), erythema, discomfort/pain, otorrhea or secretions with a foul odor. Conventional treatment is administered empirically using topical solutions composed of corticosteroids, antibiotics and antifungals. In recent years, the increase in bacterial resistance has become a global health problem and this has led to the need to look for other therapeutic alternatives that could be used as a substitute for antimicrobial drugs that are equal to or more effective. This dissertation was carried out within the scope of the conclusion of the Integrated Master's Degree in Veterinary Medicine at University Lusófona and the aim of this work was to evaluate and compare the effectiveness of integrative treatment, with a commercial topical ear solution of ozone oil, and conventional treatment, with a commercial topical ear solution composed of corticosteroids, antifungal and antibiotic, ethically accepted and performed in several CAMVs, for the resolution of otitis due to Malassezia pachydermatis in dogs. To this end, two groups of 15 animals each were formed from a sample of 30 individuals, totalling 60 ears under study. Group A underwent conventional otological treatment and group B underwent integrative otological treatment with ozone therapy. All animals were evaluated for clinical signs and ear cytology on days 0, 7 and 14 of treatment to understand their evolution. It was shown that the integrative treatment with ozone therapy used in this work was more effective compared to conventional treatment in otitis media caused by Malassezia pachydermatis after 14 days of treatment, proving to be a safe alternative because, so far, no bacterial resistance to ozone has occurred.
