Symptoms of Aural Hematomas
Most localized swellings on the inside of the ear flaps (pinnae) are hematomas, although abscesses can also occur on the pinnae, especially after a dog fight.
Owners of dogs with aural hematomas may notice one or more of the following signs:
- Soft, fluid-filled swelling on the inner surface of the ear flap
- Head-shaking (repeated, vigorous)
- Ear-scratching (repeated, vigorous)
- Warm ear
- Painful ear when touched
Dogs at Increased Risk
Dogs with particularly pendulous pinnae (long, heavy ears) tend to have an increased risk of developing aural hematomas. Dogs with outer ear infections (otitis externa) or middle ear infections (otitis media), and those with parasite infestation, are predisposed to developing this condition. Dogs living in hot, humid climates, and those that swim frequently, also at are increased risk of developing aural hematomas.
