Ear hematomas often cause cats to scratch their ears or shake their heads in response to irritation and swelling. In today's blog post, our Glendale vets explain how ear hematomas develop in our feline friends, and list symptoms and treatment options.
Ear Hematoma in Cats
A hematoma is a pocket of blood that forms within an organ or tissue. Sometimes called blood blisters, these can vary in location and size. However, in some circumstances, cats can develop ear (aural) hematomas, which appear between the cartilage and skin of your cat's ear flap.
While ear hematomas don't often develop in cats, this makes it even more critical to understand how to identify them and what to do if this ear condition occurs in your feline companion.
Causes of Ear Hematomas in Cats
Injury and trauma are both common causes of ear hematomas in cats. The small blood vessels in a cat's ear flap can become damaged, which causes them to break and leak internally. This can lead to swelling, or blood filling a pocket. Specifically, your cat's ear hematoma may be caused by:
Ear Scratching or Head Shaking
Has your cat been scratching its ears or shaking its head frequently? An ear infection or ear mites may be the root cause. Foreign objects caught in the ear or skin allergies may also be to blame.
Bites or Scratches
If your cat spends time outside, it's possible that your cat has gotten into fights with other cats or sharp thorns have made their way into your kitty's ear and scratched it.
Underlying Health Issues
While immune disorders, blood clotting deficits, or other conditions may occur less often, these and other underlying health conditions can cause ear hematomas in cats.
Signs of Ear Hematomas in Cats
If your cat has an ear hematoma, you'll most likely notice swelling or a new bump on the ear. If the hematoma is alrge enough, the ear flap itself will appear swollen, potentially causing the ear flap to droop under its own weight.
you may notice that the swelling feels squishy or tight, but be gentle – if the spot is tender, your cat will likely let you know. Along with the changes in appearance of your cat's ears, your four-legged friend's behavior will be another indication that they may have an ear hematoma. If the ear is irritated or tender, your cat may groom that spot more than usual or shy away from your touch.
Diagnosis & Treatment of Ear Hematomas in Cats
Our vets are experienced in caring for cats ears and diagnosing any conditions that may affect your kitty's health.
They can thoroughly examine your cat's ears and diagnose underlying causes of swelling, irritation, or behavioral changes. Infections, injuries, ear mites, and other causes of ear hematomas can also be diagnosed and treated.
Your vet may also use a needle to take a sample of the hematoma (also referred to as a biopsy) to confirm the nature of your cat's condition.
Treatment: Aural Hematoma Surgery for Cats
To treat aural hematomas in cats, vets will often recommend veterinary surgery. The veterinary dermatologist or veterinary surgeon will make a small surgical incision in the ear flap so the blood pocket can be drained. Tiny sutures will then be used to close the pocket and to stop blood or infection from building up again.
To further ensure blood doesn't accumulate at the site, the vet will bandage the ear.
If the hematoma on your kitty's ear is small or your cat cannot undergo anesthesia safely, your vet may choose to recommend draining the site with a needle.
While this will be a treatment option for some hematomas, it isn't ideal and the issue is likely to recur. Aural hematomas in cats can usually be treated effectively with surgery - a permanent solution to the problem. Having hematomas surgically removed can also reduce scarring.
Your veterinarian will also treat the underlying cause of the hematoma (e.g. allergy or infection).
What happens if you leave a cat ear hematoma untreated?
While ear hematomas will drain, heal and scar on their own this is not recommended. If left untreated, the following may occur:
- The ear hematoma may cause swelling while healing, which can be very painful for cats
- The ear flap may swell and prevent you from being able to treat any infection that might be present.
- It may take a very long time for ear hematomas in cats to heal on their own.
- There is an increased possibility of ear hematomas reoccurring if left to heal on their own.
- If an ear hematoma heals naturally, there is a higher risk for excess car tissue.
If your cat is suffering from an ear hematoma, it's best to have it examined by one of our veterinarians in Glendale and treated with surgery to decrease pain, speed healing and prevent the condition from reoccurring.
How much does cat ear hematoma surgery cost?
The cost of ear hematoma surgery for cats will vary based on the precise nature of the condition, your location and vet's practice, and other factors. Your veterinarian will be able to provide a cost estimate for the procedure and address your questions and concerns regarding the surgery.
Post-Surgery Recovery
Your cat could feel some amount of tenderness or discomfort for a few days following the procedure, but your vet will provide medications to address pain and prevent infection and inflammation.
Your cat will need to wear a cone to stop them from scratching or rubbing the surgical site and causing inflammation, bleeding, pulled stitches, or infection.
You will receive instructions and helpful advice from your vet on how to administer home care for your feline friend as they are recovering from surgery at home, as well as when to return for follow-up visits and to have the stitches removed.
