OTITE EXTERNA E MÉDIA EM CÃES: Revisão de Literatura

Abstract

The ear is considered the organ of hearing and balance, having the responsibility to maintain balance, the direction of the body's position in space and the understanding of noises and sounds. It is divided into outer ear, middle ear and inner ear, the inner ear being the organ of balance. Otitis is inflammation of the auditory canal and can be classified as recurrent, chronic or acute according to the evolution of the condition. Otitis externa is the most common pathology found in dogs' ears, caused by several factors such as fungi, parasites and bacteria and 50% to 89% of cases have otitis media associated. Affected animals usually show clinical signs such as pain, cephalic wiggles, itching and secretion, fetid odor, among others. A well-made diagnosis is essential, as unnecessary or incorrect medications can generate pharmacological resistance. In cases of chronic otitis media, recurrent and / or unresponsive to pharmacological treatments, a surgical approach may be necessary. The objective of this paper was to review the literature on the main causes of otitis externa and media and the main forms of treatment, seeking a better understanding of otitis in dogs. Up-to-date knowledge through veterinarians is essential, instituting a correct and efficient therapy for animals, thus decreasing pharmacological resistance.
