If your dog has been struggling with constant ear infections, you might have noticed a few signs. From the endless head shaking to some painful-looking swelling, there will be a lot of clear signs. With these, there are also a lot of possible treatment options.
However, there’s one option that we’ll talk about in this blog, and it’s often considered a last resort. It’s total ear canal ablation, TECA for short.
What Is a Total Ear Canal Ablation in Dogs?
A total ear canal ablation is a specialized surgical procedure in which the entire ear canal is removed. It might sound too drastic, but for dogs with severe ear disease that don’t respond to other treatments, this might be the saving grace.
To get a better understanding, think of it like this. The outer ear canal is like a tube that carries sound into the dog’s ear. At the end of that tube is the eardrum, and behind that is the middle ear. When chronic disease, infection, or tumors damage the ear canal beyond repair, TECA is recommended.
TECA is generally paired with a bulla osteotomy, often called the TECA-BO. Here, our vet surgeons also open up and clean the bony chamber of the middle ear. By doing so, we can help remove any lingering infection, scar tissue, and abnormal growths.
Unlike routine ear cleanings or medications, a total ear canal ablation in dogs directly addresses the root cause. It literally leaves no place left for the infection and disease.
Most dogs who will undergo this treatment have already lost a significant part of their hearing, so the ear canal’s removal won’t be a big change.
When Is a Total Ear Canal Ablation in Dogs Needed?
TECA isn’t the first option we consider. It’s only recommended when other forms of treatment no longer have control over the problem. Here are a few reasons why TECA is needed:
Chronic Ear Infections. If your dog has suffered from recurring ear infections for years, the ear canal can become permanently scarred and thick. This makes it narrower and impossible for the medication to work. The infection can also potentially spread deeper into the bony middle ear.
Tumors and Growths. Abnormal growths inside the ear canal can obstruct the passageway, causing blockages, pain, and infections.
Severe Stenosis. The narrowing of the ear canal can become a potential space for bacteria to grow. Since this narrow area is difficult to clean or treat with medications, a TECA can be recommended.
Structural Problems or Trauma. In some cases, dogs can have structural abnormalities or injuries that make the ear canal non-functional.
What Are the Benefits of a Total Ear Canal Ablation for Dogs?

One of the biggest surprises for many owners is just how life-changing a total ear canal ablation in dogs can be. Dogs who will be undergoing this procedure are usually those experiencing immense pain and discomfort.
Here’s how a TECA can benefit dogs:
Provides Relief from Chronic Pain
Dogs who were once scratching, whining, and shaking their heads all the time will find immediate relief from the chronic pain. While there’s still the matter of recovery, it’ll be considerably less discomfort compared to the main problem.
Eliminates the Infection for Good
By removing the diseased ear canal, there’s no longer a place for bacteria, yeast, or pus to build up. This means that your dog can make a full recovery without any recurring infections getting in the way.
Improves Quality of Life
Because of the comfort from the surgery, dogs will feel more alive and happier. No more chronic pain, discomfort, and irritation getting in the way of playtime, sleeping, and other normal routines.
No More Treatments
Chronic ear infections can often take up so much time with treatments and vet visits. When the diseased canal is removed, dogs will no longer need to take the medications, treatments, and visits needed for the problem.
The Total Ear Canal Ablation Procedure
TECA follows a structured step-by-step process to ensure a smooth surgery and recovery for your dog.
Pre-Operative Checks
Our vets will first do an initial exam, complete with blood tests and a physical checkup on the ears. We will use X-rays, CT scans, and MRIs to get deeper views of the ear canals and the middle ear in much better detail.
The planning stage allows us to confirm that a total ear canal ablation is the best option for your dog.
Preparation
On the day of the surgery, we will administer general anesthesia. We will also provide IV fluids and strong pain relief medications to keep them stable and comfortable. By doing so, we can keep your dog steady while we fix the issue.
Next, we prepare the surgical site by shaving the surrounding fur and applying an antiseptic to the incision areas. A final check is done, and we are ready to proceed.
Removing the Ear Canal
We will now proceed by creating a curved incision around the external ear opening. This will carefully free the entire ear canal from its surrounding tissues. The vertical and horizontal portions are removed as one continuous tube, leaving the ear flap in place.
Cleaning the Middle Ear
After removing the ear canal, we will open up the middle ear and clean it up. We remove the diseased lining, debris, or any signs of infection, and we'll scrape the bone lining the tympanic bulla.
Flushing and Closing
Next, our vets will flush the middle ear and surgical field with sterile saline and place a small drain for the leftover fluid. The incision will be closed in layers so that there won’t be any space for future debris or infections to collect.
Recovery and Hospitalization
Now that the surgery is done, we’ll proceed with recovery. Pain relief continues while your dog wakes up, and our vets will provide an Elizabethan collar to help protect the area. We will advise hospitalization for further monitoring for 1 to 3 days.
During the recovery process, we will prescribe antibiotics, pain medications, and other medicines your dog needs. Antibiotics are usually given for 2 to 4 weeks. The skin stitches will be removed after 10 to 14 days.
Risks and Complications of a Total Ear Canal Ablation in Dogs

Even though the TECA can end chronic pain, it’s still a major surgery with some possible risks.
Facial Nerve Injury. Damage to the facial nerve can cause facial nerve paralysis. You can notice this when your dog’s face droops, particularly along the eyelid and lips.
Wound Infections. As with any surgery, there can potentially be incisional swelling and infections. Discharge can also be present.
Chronic Draining. In some cases, dogs can develop long-term drainage, which usually comes from residual infection or tissue.
Horner's Syndrome. This is when the nerve damage from TECA presents as a protruding third eyelid, a smaller pupil, and a lowered upper eyelid.
Vestibular Syndrome. The damage to the inner ear can interfere with a dog’s balance, resulting in loss of coordination and head tilting.
What Is the Recovery Time for a Dog With a Total Ear Canal Ablation?
It will take about 2 to 4 weeks for the incision to heal and most of the initial discomfort to disappear. During this time, you must restrict your dog’s activity completely and follow the medication schedules we advise. Follow-up care will be required.
Full recovery typically takes 4 to 8 weeks.

Final Thoughts
A total ear canal ablation in dogs can be life-changing for pets who are stuck in a cycle of recurrent ear infections, pain, and discomfort. When no other treatments work, this can be a saving grace that lets them get another chance at a happy life.
