Inner ear dysfunction related to ear disease in Inner ear dysfunction is usually demonstrated as peripheral vestibular ataxia, but hearing loss is present with many diseases as well, although more diffi cult to detect.
The clinical examination, neurological and otoscopic examination fi ndings and diagnostic work-up with radiography or CT-scan/MRI and brainstemevoked response audiometry of patients with primary or secondary inner ear disorders are discussed.
In addition, the aetio-pathogenesis and medical or surgical therapy of those ear diseases that can result in hearing loss or peripheral vestibular ataxia are reviewed.
These include chronic otitis externa, feline infl ammatory polyps, aural neoplasia, chronic otitis media and interna, ototoxicity, congenital deafness, age-related hearing loss, geriatric canine and idiopathic feline vestibular disease and congenital vestibular syndromes.
Surgical procedures discussed include removal of infl ammatory polyps via lateral incision in the vertical ear canal, total ear canal ablation, and lateral and ventral tympanic bulla osteotomy.
