Treating Cat's Ear Hematoma: How to Thicken and Swollen

When a cat's ears swell to an exaggerated thickness, it's often a sign of an aural hematoma—a condition that not only affects the cat's appearance but can also lead to thickened earlobes, ulcers, hearing loss, and even sepsis. It's crucial to address this issue promptly. But what causes aural hematomas in cats, and how can they be treated and prevented? Let's delve into this topic in detail today.

What is an Aural Hematoma?

An aural hematoma is a bloodfilled cyst that forms between the inner and outer skin layers of a cat's earshell. Typically, this condition arises from a severe shake or scratch that causes blood vessels to rupture. If left untreated, it can lead to ear deformity and even hearing impairment.

Causes of Aural Hematomas in Cats

• Ear Infections: Bacterial or fungal otitis can cause itching and pain, prompting the cat to shake its head or scratch at its ears frequently.

• Parasites: Ear mites, for instance, can also lead to discomfort in the ears.

• Allergic Reactions: Allergies to certain substances can cause ear itching.

• Injuries: Direct physical harm, such as being bitten during a fight, can also be a cause.

How to Treat Aural Hematomas in Cats

The treatment for aural hematomas focuses on stopping bleeding, preventing infection, and removing the pooled blood. Common measures include:

1. Puncture and Drainage

If the hematoma is small and not rapidly expanding, an aseptic syringe can be used to puncture and drain the blood. Afterward, a pressure bandage is applied to reduce bleeding, which should be kept in place for 7 to 10 days before removal. While this method is relatively straightforward, maintaining the bandage can be challenging, and there's a risk of infection. There's also a chance of recurrence after the bandage is removed.

2. Surgical Treatment

For larger hematomas, surgery is often recommended. The cat is anesthetized, and cotton balls are inserted into the ear canal to prevent blood from entering. The doctor then shaves and disinfects the ear, making a 1 to 1.5 cm incision along the ear's long axis over the hematoma. The blood clot is removed, and the incision is not sutured. Instead, scattered结节 sutures are made around the original hematoma to eliminate the empty cavity. Antibiotics are then injected into the cavity daily to prevent infection. The sutures are removed after 7 to 8 days, and the cat is given broadspectrum antibiotics, such as Clavamox (amoxicillinclavulanate potassium), to prevent infection.

Preventing Aural Hematomas in Cats

• Use Ear Cleanse (pet ear cleaning solution) regularly to keep the cat's ears clean and dry, preventing the growth of ear mites and bacteria.

• If you notice your cat frequently scratching or shaking its head, it's important to inspect the ear canal promptly. If you spot any abnormal discharge, odor, or redness, seek veterinary care immediately.

• Pay attention to the cat's living environment and avoid sharp objects to reduce the risk of injury.

While aural hematomas are not usually fatal, they can cause unnecessary suffering if ignored. As pet owners, it's our responsibility to keep a close eye on our furry friends' health and seek professional help at the first sign of a problem.
