Background - Auricular hematomas are fluctuating, fluid-filled inflammations of the pinna’s concave surface in dogs. This condition occurs
as a result of violent head movement or scratches on the ear due to external otitis. Pharmacological and surgical treatments have been used
with varying results. The objective of this study was to evaluate the effect of drainage in canine auricular hematoma with local corticosteroid
deposition and the systemic administration of Prednisolone.
Methods & Results - Auricular hematoma was drained in ten dogs. Subsequently, they were treated with a single injection of 0.4 ml of
Triamcinolone Acetonide1 (6 mg/ml) into the hematoma cavity, together with oral anti-inflammatory Prednisolone2 (1 mg/kg) for 10 days.
The length of the hematoma showed no change between the first and second visits, but on the third visit, there was a significant reduction
from 6.92 to 1.17 cm. Similarly, the width of the bruise showed no change from the first to the second visit, but there was an easily seen
reduction on the last visit.
Discussion - The height of the hematoma was significantly reduced from the first to the second visit, but there were no subsequent changes.
The hematoma’s amount of fluid decreased with each visit. At the end of the study, patients showed a complete recovery from the hematoma,
with no fluid present at the last visit. Drainage of the auricular hematoma with local application of Triamcinolone Acetonide and Prednisolone
anti-inflammatory doses for 10 days appears to be an effective non-surgical treatment for canine auricular hematoma.
