What are ear hematomas in dogs?
Dog ear hematomas (also called ear or ear hematomas) occur when blood vessels rupture inside the ear flap or pinna.
As blood accumulates between the skin and cartilage, the ear becomes swollen, hot, and often painful. This collection of blood forms what is called an aural hematoma.
Key takeaways
- A dog ear hematoma occurs when blood builds up inside the ear flap due to ruptured blood vessels, most commonly caused by excessive head shaking due to ear infection or irritation.
- The most noticeable sign is sudden swelling of the ear flap, which may be hot, painful, and appear red or inflamed.
- Treatment often involves surgical drainage or suture placement to prevent recurrence, as well as addressing the underlying cause such as infection, mites, or allergies.
- Preventing ear infections and treating ear irritation promptly are the best ways to reduce the risk of developing a dog ear hematoma.
Symptoms of Ear Hematomas in Dogs
The most visible sign of a dog's ear hematoma is sudden swelling of the pinna.
If your dog develops an ear hematoma, the pinna (pinna) may appear:
- Swollen
- Red
- Warm to the touch
- Tender or painful
The swelling can affect the entire ear or only part of it. If you have an ear infection, you may also notice a foul odor or discharge from the ear.
Most ear hematomas only affect one ear, but in some cases both ears may be involved.
Causes of ear hematomas in dogs
Ear hematomas in dogs most often develop as a result of ear infections that cause irritation and excessive head shaking.
When a dog shakes its head forcefully, small blood vessels inside the ear flap (pinna) can rupture, allowing blood to pool between the skin and cartilage.
Other conditions that trigger head tremors and increase the risk of dog ear hematoma include:
More rarely, ear hematomas can be associated with:
Identifying and treating the underlying cause is essential to preventing recurrence.
How Veterinarians Diagnose Ear Hematomas in Dogs
Veterinarians diagnose a dog ear hematoma through a physical examination of the affected ear.
Your veterinarian will examine your dog's ear canal using an otoscope to look for signs of infection, mites, foreign bodies, or inflammation.
An ear swab is often taken for cytology purposes, which involves examining the sample under a microscope to detect bacteria and/or yeast.
Treatment of ear hematomas in dogs
Treatment for a dog ear hematoma focuses on reducing swelling and preventing recurrence.
Addressing the underlying causes, such as ear infections, ear mites or allergies, is also essential to prevent the hematoma from recurring.
Medical and surgical options are available, depending on the severity of the swelling and the underlying cause.
Drugs
In mild cases, medications may be used. This may include:
- Steroids to reduce inflammation
- Antibiotics for infection
- Painkillers for comfort
These treatments can also be used alongside surgical procedures.
Surgical treatment
Surgical drainage is generally recommended when the swelling is significant, painful, obstructing the ear canal, or likely to cause permanent ear deformity.
During surgery, the hematoma is opened and drained under anesthesia. However, simple drainage often leads to recurrence, meaning the swelling may return and require repeat treatment.
To reduce recurrence, veterinarians typically place a drain to allow continued fluid removal or make a surgical incision and place several sutures through the ear pinna to prevent fluid reaccumulation and promote proper healing.
Recovery and Prevention of Ear Hematomas in Dogs
Surgical Recovery of Dog Ear Hematoma
Recovery from dog ear hematoma surgery focuses on protecting the ear, preventing infection, and monitoring healing.
After surgery, your veterinarian may place a bandage on your dog's ear and head and will recommend an Elizabethan collar (E-collar). At home, you may need to administer medications by mouth or apply ear medications through a small opening in the bandage.
Monitor the bandage carefully for any slippage, swelling, drainage, or foul odor. A follow-up appointment is required so your veterinarian can assess healing and remove sutures or drains if necessary.
The E-collar must remain in place to prevent scratching or shaking of the head, which can cause trauma, disrupt stitches, or lead to recurrence.
In some cases, even with proper treatment, slight scarring can lead to slight deformity of the ear pinna.
Prevention of dog ear bruises
Preventing ear infections and controlling ear irritation are the best ways to prevent ear bruises.
Since most hematomas develop as a result of head shaking, prompt treatment of underlying ear conditions is essential.
If you notice any of the following signs, schedule a veterinary exam:
- Frequent head shaking
- Excessive ear scratching
- Redness, swelling or pain
- Foul smell from the ear
- Crusting or flow
Frequently Asked Questions About Hematomas in Dogs
Can a dog's ear hematoma heal on its own?
Small ear bruises may shrink over time, but most require veterinary treatment to prevent pain, recurrence, or permanent ear deformity. Without treatment, scarring and thickening of the ear flap are common.
Is Ear Hematoma Surgery Necessary for Dogs?
Many ear hematomas require surgery, especially if the swelling is large, painful, or likely to recur. Medical treatment can be attempted in mild cases, but recurrence is common without surgical intervention.
How long does it take for a dog to recover from ear hematoma surgery?
Most dogs recover within 2 to 3 weeks after surgery. During this time, bandage maintenance, medications, and consistent use of an Elizabethan collar are essential to prevent complications.
Can ear bruises come back?
Yes, ear bruises can recur if the underlying cause, such as an ear infection, ear mites or allergies, is not treated. It is essential to address the root cause of head tremors to avoid repeated episodes.
