An ear polyp is not a death sentence for a cat. Feline inflammatory polyps are benign growths, not cancer, and with appropriate treatment most cats go on to live completely normal lifespans. The real question isn’t how long your cat can survive with one, but how much discomfort and damage the polyp causes while it’s there, and how effectively treatment prevents it from coming back.
Ear Polyps Are Benign Growths
Inflammatory polyps grow from the mucous lining inside the middle ear cavity, the throat, or the tube connecting the two. They are not tumors in the cancerous sense. They don’t spread to other organs and they don’t become malignant. What they do is slowly expand, pushing into the ear canal, the back of the throat, or both, creating a physical obstruction that causes progressively worsening symptoms.
These polyps most commonly appear in younger cats, though they can develop at any age. The exact cause isn’t fully understood, but chronic upper respiratory infections (particularly calicivirus and herpesvirus) are suspected to play a role in triggering the inflammation that leads to polyp formation.
What Happens If a Polyp Goes Untreated
Some cats with polyps confined to the middle ear show few or no obvious symptoms early on. But the signs are typically chronic and progressive, meaning they get worse over time as the polyp grows. Depending on where the polyp extends, your cat may develop:
- Ear infections: outer ear infections, middle ear infections, or inner ear infections that keep recurring despite antibiotic treatment
- Breathing problems: loud, snoring-type breathing, gagging, or nasal discharge when the polyp grows into the back of the throat
- Neurological issues: a drooping eyelid, a constricted pupil on one side, head tilting, or loss of balance when the polyp presses on nerves near the middle ear
None of these complications are directly fatal, but they significantly erode quality of life. Chronic ear infections cause pain. Breathing obstruction disrupts sleep and eating. Balance problems make it hard for a cat to jump, climb, or move comfortably. Left alone indefinitely, a polyp will generally keep growing and the symptoms will keep compounding. A cat could technically live for years with an untreated polyp, but it would be years of increasing discomfort.
How Polyps Are Diagnosed
Your vet may spot a polyp by looking into the ear canal with an otoscope or by examining the back of the throat while your cat is sedated. But to see the full picture, especially whether the polyp has filled the bony cavity of the middle ear, advanced imaging is needed. CT scans and MRI are considered the gold standard for mapping the polyp’s size, location, and how deeply it involves the middle ear structures. This imaging is what determines the best surgical approach.
Treatment Options and Success Rates
There are two main surgical approaches, and the choice between them depends largely on how far the polyp extends into the middle ear.
Traction Avulsion
This is the simpler procedure. The vet grasps the visible portion of the polyp and pulls it out, ideally removing the stalk and base along with it. It’s fast, less expensive, and easier on the cat. The downside is that standard traction avulsion has a recurrence rate as high as 50%, because tissue at the base of the polyp is often left behind. A newer variation that combines traction with a small incision to access the ear canal (called a lateral approach) brings recurrence down to about 14%, a significant improvement.
Ventral Bulla Osteotomy
This is a more involved surgery where the vet opens the bony middle ear cavity from underneath the jaw to remove the polyp and all of its attachment tissue. Recurrence rates are the lowest of any technique, ranging from 0 to 8%, with most large studies reporting 3 to 5%. The trade-off is a higher risk of temporary nerve complications. In one study of 19 cats, more than half developed Horner’s syndrome (a drooping eyelid and constricted pupil on the affected side) after surgery, and several experienced temporary facial nerve paralysis.
Recovery After Surgery
Most cats are eating again within a day or two of surgery and go home within about three days. Surgical wounds from the more invasive procedure typically heal within two weeks. The neurological side effects, the drooping eyelid, facial weakness, or balance issues, are usually temporary. In reported cases, these signs resolved within three to six weeks. Some cats recover even faster.
The important thing to know is that these post-surgical nerve effects, while alarming to see, are not permanent in the vast majority of cats. They happen because the nerves running through and around the middle ear are temporarily disturbed during surgery.
Long-Term Outlook
Cats treated successfully for ear polyps have an excellent long-term prognosis. In published follow-up data, cats were tracked for as long as 6.5 years after treatment with no recurrence. There is no evidence that inflammatory polyps shorten a cat’s lifespan. Once the polyp is fully removed, cats return to normal activity and comfort.
If a polyp does recur after a simpler procedure, a second surgery (often the more thorough bulla osteotomy) is typically curative. Recurrence after bulla osteotomy is rare enough that most cats only need one procedure to be done with the problem permanently.
The bottom line: an ear polyp is a quality-of-life issue, not a survival issue. The sooner it’s addressed, the less chronic damage it does to the ear and surrounding structures, and the more straightforward recovery tends to be.
