![]() ![]() Aural hematoma surgery skin#The ear pinna is shaved and prepped before an incision is made through one layer of skin over the length of the hematoma. Also, the ear canal may be flushed with antiseptic during anesthesia to facilitate a thorough cleaning before beginning topical treatments at home. This can greatly expedite a successful resolution of the infection. If an ear infection exists, the ear canal may be swabbed to send samples to a reference laboratory for culture and susceptibility testing. The pet is administered a general anesthetic after pre-surgical blood work confirms that there are no contraindications precluding surgery. The window of opportunity to surgically repair an aural hematoma is typically within a week of its occurrence. This is sometimes called a cauliflower effect, and can occlude the ear canal leading to increased risk of ear infections. Left untreated, the blood will reabsorb and form scar tissue, causing the ear pinna to shrink and deform. The hematoma will probably recur, and infection can occur if the hematoma is contaminated. Aspirating the blood with a needle and syringe can deflate the pinna, but this treatment is seldom effective. Surgical repair is usually recommended for aural hematomas. In any case, an ear infection should be ruled out as an underlying reason for a hematoma. The shorter the ear pinna, the less likely that a whipping action caused the blood vessels to rupture. Another cause of a hematoma can be a trauma such as from fight wounds, and this is the more common cause of hematomas in cats. The increased blood pressure in the vessels causes them to rupture. The pain and irritation causes the dog to shake its head violently, causing a whipping effect of the ear flap. ![]() Canine hematomas are usually associated with an ear infection. Dogs and cats can be diagnosed with an aural hematoma. Because the blood cannot escape the body, the ear pinna fills like a pillow or balloon. A hematoma of the ear flap (pinna) is caused by a ruptured vessel leaking blood between the layers of skin covering the inner and outer external portion of the ear. Hematoma simply means “blood filled mass”. ![]()
