Ear Hematoma in Dogs | petMD

Canine Aural Hematoma

Ear hematomas, also known as auricular hematomas or aural hematomas, occur when blood accumulates in the flap (or pinna) of the ear.

Symptoms and Types

Ear hematomas are characterized by a swelling of the ear flap. In most cases, only one ear will be affected. However, it is possible for both ears to have hematomas. The swelling may involve the entire ear flap or it may cover only part of the ear flap.

Causes

The most common cause of an ear hematoma in dogs is an ear infection or other irritation within the ear. Ear infections cause irritation to the ear, resulting in shaking of the head which in turn causes the development of the hematoma.

Less commonly, allergic skin disease, immune disorders or blood clotting deficits can be the cause of ear hematomas.

Diagnosis

Ear hematomas are typically diagnosed by physical examination.
