If you notice any changes in your dog’s ears, such as lumps, swelling or discharge, it is important to take them to the vet immediately. Early diagnosis and treatment are important for the best possible outcome for your dog.
What are Ear Tumors?
Ear tumors are growths that occur outside or inside the ear. They can be benign (non-cancerous) or malignant (cancerous).
Benign ear tumors usually grow slowly and do not spread to other parts of the body. Malignant ear tumors, on the other hand, grow quickly and spread to other parts of the body, such as the lymph nodes, lungs, and liver.
The most common type of ear tumor is a polyp. Polyps are small, fleshy growths that can hang from the skin of the ear. They are usually benign and cause no symptoms. However, if they grow large enough, they can block the ear canal and cause hearing loss.

Treatment of Ear Tumors in Dogs
Total ear canal ablation (TECA) is the best treatment for this. Total ear canal ablation (TECA) is a surgical procedure used to remove the entire ear canal in dogs with ear tumors. This surgery is usually performed under general anesthesia and may take several hours to complete.
During TECA, the vet makes an incision in the dog’s ear and removes the entire ear canal, including the bony part of the middle ear. The skin around the ear may also be removed with the tumor.
After TECA, the dog must wear an ear bandage for several days to protect the incision. Antibiotics may also be needed to prevent infection.
TECA is a very effective treatment for ear tumors in dogs. This helps prevent the tumor from spreading to other parts of the body and improves the dog’s quality of life. However, it is important to note that TECA can also cause hearing loss and balance problems in dogs.
Here are some of the benefits of TECA for dogs with ear tumors:
- It helps prevent the tumor from spreading to other parts of the body.
- It improves the dog’s quality of life by reducing pain and discomfort.
- It is performed under general anesthesia, which means the dog is asleep during the surgery.
- Recovery time is relatively short.
Here are some of the risks of TECA for dogs with ear tumors:
- This leads to hearing loss.
- This can lead to balance problems.
- There is a risk of infection at the incision site.
- Surgery can be expensive.
If your dog is suffering from an ear tumor, talk to your veterinarian about whether TECA is an appropriate treatment. They can discuss the benefits and risks of surgery and help you make the best decision for your dog’s care.
