Ceruminous gland adenocarcinoma, or canine ear cancer, is an uncommon tumor found in dogs’ ears. It starts in the sweat glands inside the external part of a dog’s ear. This illness leads to the growth of harmful cells in and around the ear.
Dogs suffering from this ailment might constantly scratch their ears, shake their heads, or have discharge. They might also have a bad smell coming from the ear and a noticeable head tilt. It’s thought that long-lasting ear infections might lead to this cancer by harming the ceruminous glands over time.
Treatment generally involves taking out the tumor surgically. The most done surgery is a total ear canal ablation (TECA). This procedure removes the whole ear canal to get rid of the tumor completely. Yet, it’s vital to know that dogs that go through this surgery will lose hearing on that side. This is because the surgery removes the ear’s hearing parts. The life expectancy for dogs with this type of ear cancer is about five years if they get aggressive treatment. The surgery can cost between $3,500 to $6,000, based on the surgery type and other aspects.

- Chronic ear infections may increase the risk of developing ceruminous gland adenocarcinoma, with Cocker Spaniels being more susceptible to this condition than other breeds1.
- Treatment for ceruminous gland adenocarcinoma often involves surgical removal of the tumor, with total ear canal ablation being the most common procedure performed1.
- The average survival time for dogs with adenocarcinoma of the ear is approximately five years with aggressive therapy, such as surgery1.
- The cost of ear surgery for dogs with ceruminous gland adenocarcinoma can range from $3,500 to $6,000, depending on various factors1.
Signs and Symptoms of Ceruminous Gland Adenocarcinoma in Dogs
Dogs with ceruminous gland adenocarcinoma often show signs similar to an ear infection. They might scratch their ears, shake their heads, or have ear discharge. A foul odor from the ear and head tilt are common. These behaviors suggest the dog is in discomfort and needs a vet check.
Usually, ceruminous gland adenocarcinoma affects only one ear. The ear might release more fluid than with an infection, sometimes even bloody. If the tumor grows into deeper parts, the dog might lose balance, walk in circles, feel dizzy, or fall over.
Detecting these signs means your dog could have different ear problems. It’s important to get them checked by a vet. They will look inside the ear with an otoscope. This helps them find out if it’s ceruminous gland adenocarcinoma or something else. 1

Causes and Risk Factors of Ceruminous Gland Adenocarcinoma in Dogs
The exact cause of ceruminous gland adenocarcinoma in dogs is not known. However, it’s thought to link to long-term inflammation of the ceruminous glands. This inflammation is often due to ongoing or repeated ear infections. Treating ear infections quickly and thoroughly is key to lowering the risk of ceruminous gland adenocarcinoma1.
Cocker Spaniels are more likely to get this tumor than other dogs. This might be because they get ear infections more often, which can lead to the tumor. It’s crucial for owners of Cocker Spaniels to keep an eye on their dog’s ear health2.
Although this tumor is the most common one found in dog ears, it’s still rare. Owners should know about this tumor and its risk factors. This is very important for owners of Cocker Spaniels, who need to watch their dog’s ear health closely12.
Diagnosing Ceruminous Gland Adenocarcinoma in Dogs
To find out if a dog has ceruminous gland adenocarcinoma, vets do a complete check-up and tests. They use different methods to figure out if the tumor is there and how big it is.
Otoscope Examination
A vet looks inside the dog’s ear with an otoscope, a special tool. This lets them see the ear canal and ceruminous glands directly. The otoscope check helps find any clear signs of the tumor.
Sedated Ear Exam
Sometimes, a deeper ear exam with the dog sedated is needed. Sedation helps keep the dog still and stress-free during the check-up. It lets the vet get a better look at the tumor’s size and position.
Biopsy
To be sure it’s ceruminous gland adenocarcinoma, a biopsy is done. They take a small piece of the tumor to look at under a microscope. This shows if it’s cancer and gives clues on how to treat it.
CT Scan
In certain cases, vets suggest a CT scan to better understand the tumor. A CT scan shows detailed pictures of where the tumor is and how big it is. It’s crucial for planning the right treatment.
Vets combine exams and tests like otoscope checks and CT scans to properly diagnose the cancer. It’s key to figuring out how to best help the dog.

Treatment Options for Ceruminous Gland Adenocarcinoma in Dogs
Surgery is the first choice for treating dogs with ceruminous gland adenocarcinoma. Total ear canal ablation (TECA) is often the go-to procedure. It removes the affected ear canal and cleans the inner ear. However, this surgery might lead to deafness in the treated ear, as it takes out hearing structures. In cases where the cancer has spread to the skull, additional treatments like radiation or chemotherapy may be needed2.
Studies have looked at how often the cancer comes back after surgery. With TECA, there’s a 25% chance it could return. Other surgeries like lateral ear canal resection in cats see a 67% recurrence rate. Radiation therapy has a 36% recurrence chance. Both treatments can have issues, with a 5% to 56% chance of complications2.
Treatment costs might hold some people back. Surgery costs, especially with a board-certified vet, can range from $3,500 to $6,000. This includes procedures like TECA or the more extensive TECA with bulla osteotomy1.
After surgery or radiation, dogs need a follow-up. They should be checked every three months to keep an eye out for any problems or the cancer coming back. Without the right treatment and checks, the cancer could spread or get worse2.
| Treatment Option | Recurrence Rate | Complication Occurrence | Deafness in Operated Ear |
|---|---|---|---|
| Total Ear Canal Ablation (TECA) | 25% | Ranges from 5% to 56% | Yes |
| Lateral Ear Canal Resection in Cats | 67% | Ranges from 5% to 56% | Yes |
| Radiation Therapy | 36% | Ranges from 5% to 56% | No |

Recovery and Management of Ceruminous Gland Adenocarcinoma in Dogs
After surgery, dogs need time to adjust and heal. They might lose hearing in the affected ear. So, it’s vital to give them prescribed meds, let them rest, and watch for any signs of the cancer coming back or other issues.
Medicines play a big role in healing after surgery for this type of cancer in dogs. Pain killers, antibiotics, and meds to reduce swelling are common. Following the vet’s advice on how much and how often to give these meds is key for a good recoverypost-surgery care1.
Dogs need peace and quiet to heal well. They should move around as little as possible to avoid hurting the surgery spot. A comfortable spot to rest is very important during this time.
“Rest is crucial for the recovery process. Dogs need a calm and stress-free environment, with limited physical activity, to allow their bodies to heal properly.”
Seeing the vet regularly after surgery is a must. It helps catch any problems early and check how well the healing is going. The vet might do more tests or scans to make sure the cancer hasn’t come back.

CO2 Laser Ablation for Ceruminous Gland Adenocarcinoma in Dogs
Dogs with ceruminous gland adenocarcinoma have a new treatment option. This is CO2 laser ablation. It uses a CO2 laser to cut out tumor tissue. The procedure examines the ear canal with a video-otoscope.
The laser emits a 10000nm wavelength. This is readily absorbed by the tumor, making removal precise and effective.
CO2 laser ablation is gaining ground in treating this cancer in dogs. It’s less invasive than surgery and could lower chances of the cancer coming back3. The laser’s settings can be adjusted for delicate ear canal operations4.
CO2 laser ablation helps cut down on post-surgery pain and infection risk. It seals blood vessels up to 0.5 mm wide. This reduces bleeding and complications after the surgery4.
By sealing vessels, the laser lessens bleeding. This helps in removing tumors cleanly and efficiently.
This method has several benefits compared to traditional surgery. It lowers infection risk, seals nerves, and reduces pain after the operation4. The CO2 laser’s precision allows vets to remove masses in the ear safely4.
Talking to a vet oncologist is key before choosing CO2 laser ablation. They will consider the size of the tumor and your dog’s health. This ensures the best treatment plan is chosen.
The cost of CO2 laser ablation varies. It depends on the tumor’s size and location, and the dog’s health3. Always discuss expenses and payment options with your vet.
Prognosis for Dogs with Ceruminous Gland Adenocarcinoma
The outlook for dogs with ceruminous gland adenocarcinoma depends on several things. These include how far the tumor has spread and the success of treatment. Most dogs receiving aggressive surgery live over 2 years after treatment2. Yet, if the cancer has spread, the outlook is not good5.
This type of cancer can aggressively attack nearby areas like skull bones. It can also spread to lymph nodes and lungs5. Spotting and treating it early can help improve the dog’s chances. However, cancer spreading to lymph nodes or lungs means a worse outlook5. Discussing treatment options with a vet oncologist is critical for choosing the right path.
| Treatment Modality | Recurrence Rate |
|---|---|
| Surgery (total ear canal ablation and bulla osteotomy) | 25%2 |
| Surgery (lateral ear canal resection) | 67%2 |
| Radiation therapy | 36%2 |
| Complications associated with surgery | Varied occurrence from 5% to 56%2 |
Treatment choices also affect the dog’s prognosis. Surgical removal and radiation are options5. Dogs often live over 2 years after aggressive surgery like ear canal removal5. But, surgery’s success varies by procedure2. Radiation can see a 36% recurrence rate2.
Cancer spread to lymph nodes or lungs links to worse outcomes5. Regular check-ups are key to catching any return or spread of cancer. The overall outlook needs to be looked at individually. A vet oncologist can help ensure the best care.
Cost of Treatment for Ceruminous Gland Adenocarcinoma in Dogs
The treatment for ceruminous gland adenocarcinoma in dogs can be costly. The price varies based on the treatment and the dog’s needs. Surgery, like a total ear canal ablation (TECA), is often used. This surgery removes the entire ear canal and nearby structures.
The cost for TECA surgery ranges from $3,500 to $6,000 with a board-certified vet surgeon1. Remember, this might not include extra services like blood tests, scans, and care after surgery. These extras can increase the total cost. The final price is affected by the surgery’s complexity and the follow-up care needed.
Talk about money matters with your veterinarian early on. They can give you a detailed cost based on your dog’s particular case. They might also suggest ways to handle these costs, like pet insurance or payment plans. It’s key to weigh the pros of treatment against your financial limits to make the best choice for your pet.
Financial considerations for the treatment of ceruminous gland adenocarcinoma in dogs:
| Treatment | Cost Range |
