- An ear hematoma is a blood blister inside the ear flap. A hematoma results from broken blood vessels. Bleeding occurs within the tissues, which results in swelling and the accumulation of fluid. Swelling is visible, and there may be redness. The ear flap is usually warm to the touch.
- An ear hematoma often occurs suddenly. Broken blood vessels may be caused by fighting, or the injury may be self-inflicted. A dog or cat with ear mites often shakes its head so vigorously that the fragile blood vessels rupture. Intense scratching can break blood vessels as well.
- The veterinarian will visually inspect the ear flap. He may withdraw fluid from the area for microscopic examination. The presence of blood in the fluid will confirm the diagnosis of a hematoma. The ears may also be examined for the presence of ear mites or signs of infection.
- The veterinarian will decide which procedure to use, depending on the severity of the hematoma. One method of treatment involves sedating the pet and placing a drain--called a teat cannula--into the tip of the ear, allowing the ear to drain for approximately 3 weeks. Another method of treatment involves making a surgical incision in the ear to drain the fluid. Multiple sutures are placed in the ear to seal it back together. The stitches are then removed in 7 to 10 days. An ear hematoma will resolve itself if left untreated but usually results in a deformity of the ear.
- Prevention is the best course of action to prevent deformity or further ear problems. A dog or cat that is shaking its head or scratching repeatedly should be taken to a veterinarian for further examination. Regular exams are essential to maintain good health. Infection or inflammation should be treated promptly. Pets should be treated for parasites such as ear mites and fleas. It may be necessary to repeat treatments.
- Allergies can also result in hematoma or other health conditions. Many pets suffer from allergies to food, flea collars, pet products as well as pollen, dust and household cleaners. Allergies may cause intense itching, which results in self-inflicted injuries due to intense scratching. Pets that are allowed outside may fight with other animals and sustain wounds that result in ear hematoma. Even household pets that play together may get a little rough during play and broken blood vessels could occur, resulting in an ear hematoma. It is important to seek treatment at the first sign of an ear hematoma.
