Hematoma of the Ear Flap ------------------------ General Information Hematoma of the ear flap is an accumulation of blood between the cartilage and skin of the ear flap. It is caused by damage to the cartilage from vigorous repeated head shaking, or scratching at the ears with the back feet. Occasionally the damage results from the ear striking a sharp edge during head shaking. The most common underlying causes of head shaking are ear infections, ear mites and fleas. Important Points in Treatment 1. In most instances, general anesthesia is necessary for withdrawal of the hematoma fluid and surgical repair. 2. Treatment of ear infections and/or ear mites is necessary to allow healing and prevent recurrence of the conditions that caused the hematoma. 3. Give all medication as directed. Call the doctor if you cannot give the medication as directed or are unsure if you are properly treating the ear. 4. If your pet has a bandage or restraint device attached to the ear flap, please make an appointment for its removal. 5. Instructions for care of incisions, drain tubes and/or sutures: Notify the Doctor if Any of the Following Occur: * Your pet exhibits discomfort by rubbing or pawing at its ears or by shaking its head. * Fluid continues to accumulate under the skin of the ear.
