Ear cancer in dogs is a serious condition that often requires surgical intervention. Depending on the location and severity of the cancer, different treatment options may be considered. Early diagnosis and prompt treatment are essential to improve your dog’s quality of life and prognosis.
Surgical Options for Treating Ear Cancer in Dogs
-
Pinnectomy (Partial or Total Ear Flap Removal)
When cancer affects the pinna (the outer ear flap), a partial or total pinnectomy may be necessary. In a partial pinnectomy, only the affected portion of the ear flap is removed, whereas in a total pinnectomy, the entire ear flap is surgically removed. This procedure aims to prevent the spread of cancer and improve the dog's chances of recovery. -
Total Ear Canal Ablation with Lateral Bulla Osteotomy (TECA-LBO)
For more severe cases of ear cancer that involve the ear canal, a more complex surgery called total ear canal ablation with lateral bulla osteotomy (TECA-LBO) is performed. In this procedure, the entire ear canal is removed, and the tympanic bulla (the bony structure at the base of the skull) is opened to eliminate any cancerous or secretory structures. After this surgery, the dog will have an ear flap but no ear canal. Although hearing may be diminished, the procedure prevents further complications and improves the dog's health.
Non-Surgical Treatments
-
Radiation Therapy
For tumors that are too advanced or located in areas that make surgery difficult—such as the middle or inner ear—radiation therapy may be recommended. This treatment involves targeting cancer cells with radiation to shrink tumors and slow their progression. Radiation therapy requires multiple anesthetized sessions spread out over several days. -
Chemotherapy
If the cancer has metastasized (spread to other parts of the body), chemotherapy may be used to target cancer cells throughout the body. Chemotherapy is typically recommended when surgery or radiation alone is not sufficient to treat the cancer.
Supportive Care for Dogs with Ear Cancer
In addition to the main treatments, supportive care is crucial for managing your dog's comfort and recovery. Pain medications will be prescribed to help alleviate discomfort, and antibiotics may be necessary to prevent or manage infections following surgery. Your veterinarian will guide you through the process of aftercare to ensure your dog recovers as smoothly as possible.
Treating ear cancer in dogs often involves surgical intervention, but the specific approach depends on the location and severity of the tumor. From pinnectomy to the more advanced TECA-LBO procedure, surgery can effectively manage and remove cancerous growths. Radiation therapy and chemotherapy may also be recommended in certain cases. If your dog is diagnosed with ear cancer, consult with your veterinarian about the best treatment plan for your pet.
