Ear Hematoma. The Complete Veterinarians Guide To Understanding, Treating and Avoiding Them.

I get these shaking head painful and swollen dog ear questions too often. Perhaps for me the 'old hat stuff' has progressed into dismay that I haven't adequately gotten the word out? Maybe the whole pet loving world doesn't know what an ear hematoma, or, aural hematoma is yet?

So here I go... pull out soapbox and cross fingers that I can spare a dog the excessive expense of an emergency visit, or, the worsening of a condition that allows the snowball to escalate in to needed a TECA (total ear canal ablation), and maybe even help a pet parent out there thwart a bug at the pass and save their pet from having an ear that resembles the one above.

If you think this is painful, you would be right! A hot, swollen, tender, blood filled pillow hanging off the side of your face blocking your ears from any kind of basic function, usually corking off infection inside your ears so it can stealthily fester and ferment while the world is far beyond reach, IS ouchy!

Note the perpendicular ear pinna and the head tilt.

I have seen many of these and in each case the degree of pinna damage, area of the swelling (base of ear or tip of ear), chronicity of disease (how many times has this ear flap been down this road?), and patient and client abilities and expectations.

I always discuss how the hematoma happened, or at least why I think it happened?

Possible causes include;

1. Ear Infection (about 40 % of the time). The ear is usually smelly and full of fluid, goopy soupy discharge, red, and painful. If your dog fits this description spend time talking to your vet about how the infection happened and how you can avoid it from happening again. Most of the repeat hematomas are infection or allergy. Your pet is very likely to be back here again. Avoid this if at all possible.

2. Allergies, about 40 % of the time. The ears are usually red but are not smelly or have any fluid in them. If your dog has allergies ask for a referral to a dermatologist sooner versus later.

3. Trauma, about 15 % of the time. The puppy and the adult dog are playing and the next thing you know someone needs an e-collar.

4. Idiopathic,, also known as, "we don't know?" I would guess these are about 2%

At the clinic I usually use a teat canula (this is what the dairy farmers place in the nipples of a diary cow with a clogged gland) to correct the severely swollen full pinna hematomas. For the very small fluid pockets at the ear base I remove the fluid and add a dilute steroid to stop the inflammatory process. For cats I use a through and through suture technique after an "S" incision is made on the medial side of the pinna.

This is what the ear looks like after three weeks of the canula being in place. The wrinkling and thickening of the ear pinna in these cases may be due to the chronicity of this ear hematoma, delay in seeking medical therapy, or not addressing the underlying problem adequately. This is why I advise getting these cases early and aggressively.

After 3 weeks the teat canula is removed. There should not be any discharge or swelling during the last week.

The ear is painful. We numb it with a local lidocaine block, but, we still place a muzzle.

The most important part of the treatment of an ear hematoma is to figure out what caused it. Both ears should be examined with an otoscope to look for infection, parasites, debris, polyps, and even tumors. I have found some crazy stuff in those ears, and every pet was telling me there was a problem by shaking, rubbing, or tilting their head to the side.

In many cases cytology of the ear may also be done. This allows us to diagnose the infection and more appropriately provide a focused treatment option.

The teat canula is sutured and glued into place. 

The end of the canula needs to be checked twice daily to make sure it doesn't get clogged. It is after all there to drain the fluid.

Daisy gives a shrug and smirk of disapproval.

Daisy is ready to go home.

A teat canula should stay in for three weeks. The e-collar should stay on for the first 3-5 days, and then if the head continues to shake, or the pet rubs or paws at the ear.

Here is the break down of Daisy's ear hematoma repair;
 Exam $50
 Aural Hematoma Repair $65
 Medications; NSAID and ear antibiotic $50
 E-collar $20
 Ear Cleaner $22
In most cases with client compliance we do not charge for re-checks or the canula removal.

For those pups who have itchy painful ears, or for those who have not progressed to hematomas (but are well on their way) I wrap the ear to the head. The disadvantage of this is if there is an infection in the ear. A wrapped ear needs air, monitoring, and care. Only wrap an ear that is NOT infected. And, be very careful to NOT cut these bandages off (you don't want to add injury to insult).

I always instruct my ear clients on how to clean their pets ears. Here is a video on how I recommend doing this. It should be quick, easy, stress and pain free. I also advise them on what to have ready at home if head shaking starts again. I typically advise keeping diphenhydramine on hand and starting to clean the ears as soon as a problem seems eminent. Red ears, head rubbing, pawing or scratching at the ears all indicate that it is time to look and smell under the hood.
