Tumors of The Ear Carnal in Dogs

Tumors may develop from any of the structures lining or supporting the ear canal, including the outer layer of skin, the glands that produce earwax and oil, or any of the bones, connective tissues, muscles, or middle layers of the skin. Tumors of the external ear canal and pinna are more common than tumors of the middle or inner ear.

The majority of ear tumors are not cancerous and some do not even need treatment unless they are causing problems or pain in your dog. However, many veterinarians believe that it is best to remove ear tumors, whether they are in the tissues, bones, or glands, or need to be removed to prevent infection, pain, and growth.

Although there does not appear to be a genetic or hereditary cause for ear canal tumors, chronic inflammation is believed to play a role. German Shepherds and Cocker Spaniels, for example, are at increased risk of developing these tumors. This may be related to the tendency of both breeds to have recurrent and severe ear infections

Types of Ear Tumors in Dogs and Cats

• Ceruminous Gland Adenoma (Benign Ear Wax Gland Tumors)
• Ceruminous Gland Adenocarcinoma (Malignant Ear Wax Gland Tumors)
• Nasopharyngeal Polyps (Inflammatory Polyps)
• Squamous Cell Carcinoma

Causes of Tumors of The Ear Carnal in Dogs

The reason why a particular pet may develop this, or any other tumor or cancer, is not straightforward. Very few tumors and cancers have a single known cause. Most seem to be caused by a complex mix of risk factors, some environmental and some genetic or hereditary.

Pets with a history of long-term (chronic) otitis externa have an increased risk for ear tumors. The incidence of ear tumors, both benign and malignant, is more prevalent in American Cocker Spaniels than in other canine breeds. This predisposition is likely brought about by chronic inflammation that is common to the breed.

Symptoms of Ear Carnal Tumors in Dogs

The side effects of ear tumors depend on where the tumor is and how large it is. Some of the most often reported signs of ear tumors are:

• Visible growth in the ear
• Shaking head
• Stumbling or falling due to lack of balance
• Tilting the head
• Swelling of the ear
• Scratching or rubbing the ear
• Whining or crying in pain when ear is touched
• Foul smell in the ear
• Bloody or yellow discharge
• Chronic ear infections

Treatment

The most common treatment is surgical removal of the lump(s). Laser surgery is very effective when it is available. Sometimes extensive surgery is required and it is necessary to ablate (remove) the whole ear canal.The most common treatment is surgical removal of the lump(s).
