An aural hematoma is an accumulation of blood between the skin and cartilage of the ear in dogs, often caused by traumaA trauma refers to a physical injury or damage caused by external force. Traumas can range from simple cuts to severe multiple injuries. or intense scratching.
The most important facts at a glance
An aural hematoma in dogs is caused by the bursting of blood vessels in the ear, which leads to an accumulation of blood between the cartilage and skin. This causes the ear to swell and can cause pain. Common triggers are traumaA trauma refers to a physical injury or damage caused by external force. Traumas can range from simple cuts to severe multiple injuries. from intense scratching or head shaking, often due to ear infections, mites, or allergies that cause itching. Some dog breeds are genetically more susceptible to aural hematomas.
DiagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. is made by a clinical examination of the affected ear, supplemented by tests for infections or parasites. Treatment usually involves surgical drainageDrainage refers to the removal of fluid from body cavities, Wounds, or inflamed areas, often using a tube or other device. It is used to prevent infection and promote healing. to drain the blood and fix the tissue to the cartilage. Alternatively, conservative treatment with needle drainageDrainage refers to the removal of fluid from body cavities, Wounds, or inflamed areas, often using a tube or other device. It is used to prevent infection and promote healing. and cortisone injections can be carried out, although there is a risk of recurrence. The underlying cause must also be treated to prevent recurrence.

Causes
An aural hematoma occurs when blood vessels in the ear burst and blood collects between the cartilage layer and the skin above. This blood accumulation causes the ear to swell and feel soft and spongy. The pressure from the blood accumulation can cause pain and deform the ear if left untreated.
The most common cause of an aural hematoma is traumaA trauma refers to a physical injury or damage caused by external force. Traumas can range from simple cuts to severe multiple injuries. to the ear, often from intense scratching or head shaking. These behaviors often occur when the dog suffers from ear infections, mites, or allergies that cause itching. With vigorous head shaking or scratching, the delicate blood vessels in the ear can burst.
Ear infections often lead to aural hematomas because they cause severe itching and discomfort, which cause the dog to shake or scratch its ear. Allergies can also play a role, as they can irritate the skin in the ear and lead to the same behaviors. Parasites such as ear mites are also a common cause. In addition, the tendency to develop aural hematomas may be genetic in some dog breeds.
Symptoms
The symptoms of an aural hematoma are usually easy to recognize. The affected ear swells and feels warm and soft, almost like a fluid-filled cushion. The dog may show signs of discomfort and try to scratch the ear or shake its head.
Another common symptom is a visible bruise or discoloration of the skin on the inside of the ear. These changes are due to the accumulation of blood under the skin. In severe cases, the ear may appear deformed due to the swelling.
Dogs with an aural hematoma may also show signs of pain or Irritability, especially when the affected ear is touched.

Diagnosis
An aural hematoma is usually diagnosed by a thorough clinical examination of the affected ear. The veterinarian will palpate the ear and look for swelling, pain responses, and other signs of blood accumulation.
To determine the underlying cause of the aural hematoma, the veterinarian may also examine the ear for infections, mites, or other conditions. This can be done by examining the ear with an otoscopeAn otoscope is a medical instrument used to examine the external auditory canal and the eardrum. Otoscopy is a standard procedure in veterinary medicine for the diagnosis of ear diseases in dogs and cats. or by taking swabs for microscopic examination.

Therapy
Treatment for an aural hematoma can vary depending on the severity of the blood accumulation and the underlying cause. A common method is surgical drainageDrainage refers to the removal of fluid from body cavities, Wounds, or inflamed areas, often using a tube or other device. It is used to prevent infection and promote healing., in which a small incision is made to drain the blood. After drainageDrainage refers to the removal of fluid from body cavities, Wounds, or inflamed areas, often using a tube or other device. It is used to prevent infection and promote healing., a suturing technique is often used to reattach the tissue to the cartilage and prevent the formation of a new hematoma.
In some cases, conservative treatment with needle drainageDrainage refers to the removal of fluid from body cavities, Wounds, or inflamed areas, often using a tube or other device. It is used to prevent infection and promote healing. and cortisone injections can be used to reduce inflammation and promote healing. This method is less invasiveInvasive describes medical procedures or pathogens that enter the body or penetrate tissue. In medicine, invasive procedures can range from minimally invasive techniques to open surgery. but may carry a higher risk of the aural hematoma recurring.
It is important to treat the underlying cause of the aural hematoma to prevent recurrence. This includes treating ear infections with antibiotics or antifungals, as well as controlling allergies or parasites. Regular ear cleaning can help prevent infections.
Prognosis and follow-up care

Traumas can range from simple cuts to severe multiple injuries. to the ear. This includes regular checking and cleaning of the ears, especially in dogs prone to ear infections or allergies.
Controlling parasites, such as ear mites, is also crucial, as they often cause itching and irritation that lead to Scratching and head shaking. Regular veterinary examinations can help detect and treat parasiteA parasite is an organism that lives on or in another living being (the host) and feeds at its expense. Parasites can cause a variety of diseases in animals and humans. infestations early.
For dogs prone to allergies, a hypoallergenic diet or medication may be necessary to control symptoms. Treating ear problems early and avoiding irritants can also reduce the risk of an aural hematoma.
Outlook on current research
Current research on aural hematomas in dogs focuses on improving diagnostic and treatment methods to shorten healing time and minimize the risk of complications. Studies have shown that the cause of aural hematomas is often due to repeated scratching or shaking of the head, which can occur with allergies, ear infections, or parasiteA parasite is an organism that lives on or in another living being (the host) and feeds at its expense. Parasites can cause a variety of diseases in animals and humans. infestations. Researchers continue to investigate the underlying causes to develop preventive measures that can prevent such injuries.
Another significant area of research is the development of new surgical techniques and non-operative treatment approaches. Traditionally, an aural hematoma is treated surgically by draining the blood accumulation and fixing the ear to support healing. However, more recent studies are examining the effectiveness of minimally invasiveInvasive describes medical procedures or pathogens that enter the body or penetrate tissue. In medicine, invasive procedures can range from minimally invasive techniques to open surgery. methods, such as aspiration in combination with the administration of steroidsSteroids are a group of lipids that include both hormones and certain medications. In veterinary medicine, steroids are used to treat inflammatory conditions, allergies, and autoimmune diseases in dogs and cats. or the use of compression bandages, to reduce the need for surgical intervention.
Another promising area of research is the study of geneticsGenetics is the science of genes, heredity, and the variation of organisms. It studies how genetic information is passed from generation to generation and how it influences the development, appearance, and behavior of living things. and breeding lines to determine whether certain breeds or genetic factors increase the risk of developing aural hematomas. In the long term, this information could help inform breeding decisions to reduce the occurrence of this condition.
In addition, there are studies on the role of nutrition and lifestyle in the preventionPrevention includes measures taken to prevent diseases or injuries.
