Otitis Interna

Otitis interna describes inflammation within the inner ear, the deepest portion of the ear structure that houses the organs of hearing and balance. This area sits behind the eardrum and the middle ear, enclosed in bone, and when it becomes inflamed the signs tend to relate more to balance and coordination than to the kind of ear discomfort owners may associate with outer ear infections. Owners often arrive at this page because their dog or cat has developed a head tilt, seems unsteady on their feet, or is struggling with balance in a way that appeared quite suddenly. In some cases there may be a history of ear trouble, but in others the signs can seem to come from nowhere. The eyes may also show unusual movement, and the animal may seem reluctant to move or may circle in one direction. This page explores the patterns that can point towards inner ear inflammation, what may be happening beneath the surface to produce these signs, how the condition is investigated through examination and imaging, and the range of approaches that exist to address the underlying cause and support recovery. The structure is designed to help you understand what you may be observing and what shape the process of working through it might take.
