This approach allows your vet to remove all of the fluid and suturing the two layers together forms a strong fibrous bond between the two and helps to prevent a recurrence. This involves giving your pet a full general anaesthetic, draining the fluid from the pinna and then suturing the two flaps of skin together. Most cases, however, go on to require surgery. If there is only a mild swelling and there are other complicating factors (like old age or other ongoing disease problems) then your vet may suggest a course of medication and leaving the haematoma to be partially resorbed with time. Various differing approaches may be tried in the treatment of aural haematomas. This ‘self-abuse’ can very easily damage the fragile blood vessels within the pinna and cause an aural haematoma to form. Ear infections, mites, inflammation and foreign objects can be very uncomfortable and your pets reaction would probably be to shake its head or scratch vigorously at the ear. This damage to the blood vessels may be caused by any form of trauma like being hit by a car or bitten by another animal, but it is most commonly caused by the pet itself. An aural haematoma (blood blister of the ear) forms when one or more of these vessels rupture and the leaking blood pockets in the space between the two layers of skin. Each one of your pet’s ear lobes (pinna) is made up of two layers of opposing skin held together with fibrous tissue, with nerves and blood vessels running between the two layers.
