This study reports 20 clinical cases of aural haematoma in dogs, aiming to identify potential underlying causes. Ear canal cytology was performed to evaluate the presence of bacteria, yeast, and inflammatory cells. Prior to surgery, video otoscopy of both ear canals was conducted, with the ear under examination positioned uppermost. Changes in the ear canal, including wall patterns and patency, were documented. Cytological analysis revealed yeast colonies, predominantly Malassezia pachydermatis, and bacterial colonies primarily composed of cocci. Video otoscopic examination identified erythema, ear canal hyperplasia, polyps, and ceruminous gland hyperplasia. In some cases, polyps, ceruminous gland hyperplasia, and ear canal stenosis limited visualization of the tympanic membrane and deeper portions of the ear canal. These findings indicate that while ear cytology and video otoscopy provide valuable diagnostic information in dogs with aural haematomas, structural changes such as polyps, ceruminous gland hyperplasia, and canal stenosis may hinder comprehensive assessment of the ear canal.
