Inflammatory Polyps in Cats
- Inflammatory polyps are benign tissue growths that can form in a cat's ear, throat, or the space behind the nose.
- Common signs include noisy breathing, sneezing, nasal discharge, gagging, swallowing trouble, head tilt, ear scratching, and recurrent ear infections.
- Diagnosis often requires a full oral and ear exam, and some cats need sedation or anesthesia for otoscopy, imaging, or endoscopy.
- Treatment usually involves removing the polyp, but the exact approach can range from traction removal to more advanced surgery if recurrence or middle ear disease is present.
- See your vet immediately if your cat has open-mouth breathing, severe breathing effort, marked balance problems, or cannot eat or drink normally.
Overview
Inflammatory polyps in cats are noncancerous growths made of inflamed tissue. You may also hear them called aural polyps, nasopharyngeal polyps, or oropharyngeal polyps, depending on where they are found. These masses can develop from the lining of the middle ear, auditory tube, or nearby throat tissues, then extend into the ear canal or the back of the throat. Even though they are benign, they can still cause major day-to-day problems because they block airflow, irritate nearby tissue, and interfere with swallowing or ear function.
These polyps are seen most often in kittens and young cats, although older cats can develop them too. Many affected cats first look like they have a stubborn upper respiratory infection or chronic ear disease. A pet parent may notice loud breathing, snoring sounds while awake, sneezing, nasal discharge, gagging, or repeated ear issues. Because the signs overlap with infections, foreign material, tumors, and fungal disease, your vet usually needs a hands-on exam and sometimes imaging to sort out the cause.
Inflammatory polyps are not the same as cancer, but they should still be taken seriously. A growing polyp can narrow the nasopharynx, affect the middle ear, and in some cats lead to head tilt, balance changes, or Horner syndrome. The good news is that many cats do well once the polyp is identified and removed. The challenge is that recurrence can happen, especially if the stalk and tissue of origin are not fully addressed.
Because there is more than one reasonable way to manage these cases, treatment planning often depends on your cat's age, symptoms, exam findings, imaging results, and your goals for care. Some cats can be treated with a less invasive removal approach, while others need referral-level surgery to reduce recurrence and address disease deeper in the middle ear.
Signs & Symptoms
- Noisy breathing or snoring sounds while awake
- Sneezing
- Nasal discharge
- Gagging or retching
- Difficulty swallowing
- Reduced appetite from trouble eating or breathing
- Open-mouth breathing or increased breathing effort
- Head tilt
- Ear scratching or pawing at the ear
- Head shaking
- Ear discharge
- Recurrent ear infections
- Balance problems or wobbliness
- Nystagmus or abnormal eye movements
- Horner syndrome changes such as a droopy eyelid or small pupil
The signs depend on where the polyp is growing. Polyps extending into the nasopharynx often cause upper airway signs such as stertor, which is a low-pitched congested breathing sound, along with sneezing, nasal discharge, gagging, and swallowing trouble. Some cats seem to snore while awake or make a sudden harsh noise when excited, eating, or grooming. If the mass is large enough, breathing effort can increase and eating may become difficult.
When the polyp affects the ear canal or middle ear, the pattern can look more like chronic ear disease. Cats may scratch at one ear, shake their head, develop discharge, or keep getting treated for ear infections that return. If the middle ear is involved, some cats develop neurologic signs such as head tilt, ataxia, nystagmus, or Horner syndrome. Those signs warrant prompt veterinary attention because they can overlap with other serious ear and neurologic conditions.
Some cats have a mix of respiratory and ear signs at the same time. That combination is an important clue. A young cat with noisy breathing plus head tilt or recurrent ear issues should raise concern for an inflammatory polyp. Still, these signs are not specific, so your vet may also consider infections, foreign bodies, masses, severe rhinitis, or fungal disease in the differential list.
See your vet immediately if your cat is open-mouth breathing, struggling for air, cannot swallow normally, or seems suddenly off balance. Those signs can become urgent fast, even when the underlying mass is benign.
Diagnosis
Diagnosis starts with a careful history and physical exam. Your vet will want to know whether the main problem has been noisy breathing, chronic sneezing, repeated ear infections, swallowing trouble, or balance changes. A full ear exam and oral exam are important because inflammatory polyps can hide in the horizontal ear canal or behind the soft palate. In many cats, sedation or general anesthesia is needed so your vet can safely examine the nasopharynx, retract the soft palate, and perform a complete otoscopic exam.
If a polyp is visible, your vet may already have a strong working diagnosis. Even then, additional testing is often recommended to understand where the mass starts and whether the middle ear is involved. Skull radiographs can sometimes show changes in the tympanic bullae, but CT is often more helpful when the polyp cannot be fully seen or when surgery is being planned. MRI may be used in selected cases, especially if neurologic signs or another type of mass is a concern.
Definitive confirmation usually comes from removal and histopathology. Sending tissue to the lab helps confirm that the mass is an inflammatory polyp rather than a different benign growth, fungal lesion, or tumor. Your vet may also recommend ear cytology, culture in selected cases, or other tests if discharge or infection is present. Cats with chronic nasal signs may need rhinoscopy or endoscopy depending on the case.
Because the signs overlap with several other conditions, diagnosis is partly about ruling out look-alikes. Depending on your cat's age and symptoms, your vet may consider chronic rhinitis, ear infection with middle ear involvement, foreign material, nasopharyngeal stenosis, fungal disease such as cryptococcosis, or neoplasia. The goal is not only to identify the mass, but also to choose the least invasive workup that still gives enough information to guide treatment.
Causes & Risk Factors
The exact cause of inflammatory polyps in cats is still not fully settled. These growths are thought to arise from the mucosal lining of the middle ear, auditory tube, or pharynx. Chronic inflammation has long been suspected to play a role, and many clinicians associate polyps with a history of upper respiratory disease or chronic ear inflammation. However, current veterinary references note that a clear, consistent link to specific infectious agents has not been proven in polyp tissue.
Several theories have been proposed, including congenital factors, genetic predisposition, and inflammation following infection early in life. Cornell notes that these polyps are seen most often in kittens and very young cats, which supports the idea that early inflammatory change may matter. Even so, not every young cat with a respiratory infection develops a polyp, and not every cat with a polyp has a clear infection history. That is why your vet may describe the cause as multifactorial or uncertain.
Age is one of the more practical risk clues. Young cats are overrepresented, especially when the signs include noisy breathing plus ear problems. A history of recurrent ear disease, chronic nasal discharge, or previous upper respiratory signs may increase suspicion, but these are not proven causes on their own. In some cats, the first obvious problem is not inflammation but obstruction, meaning the polyp has quietly grown until it starts affecting airflow or ear function.
For pet parents, the key takeaway is that inflammatory polyps are not caused by anything you did wrong. They are also not considered contagious in the way an active respiratory infection can be. The important next step is getting the location and extent defined so your vet can discuss realistic treatment options and recurrence risk.

Prevention
There is no guaranteed way to prevent inflammatory polyps in cats because the exact cause is not fully known. Still, early attention to chronic respiratory and ear signs may help reduce prolonged inflammation and may allow a problem to be found before it becomes more obstructive. If your cat has repeated sneezing, chronic nasal discharge, recurrent ear infections, or noisy breathing that does not fit a simple cold, it is worth scheduling a recheck rather than waiting it out.
Routine veterinary exams matter, especially for kittens and young cats with a history of upper respiratory disease. A cat that keeps getting treated for ear debris or congestion without fully improving may need a deeper look into the ear canal and nasopharynx. In some cases, what seems like recurring infection is actually a hidden mass causing ongoing irritation and poor drainage.
Good general health care also supports earlier detection. Keep up with wellness visits, discuss any breathing noise that happens during sleep or excitement, and mention subtle neurologic changes such as head tilt or balance issues. If your cat has chronic ear disease, ask whether the eardrum and middle ear can be adequately assessed or whether referral imaging would be useful.
Prevention is really about vigilance and follow-through. Since recurrence can happen after removal, post-treatment monitoring is part of prevention too. If noisy breathing, ear signs, or swallowing trouble return, your vet may recommend re-examination sooner rather than later to catch regrowth while the problem is still manageable.
Prognosis & Recovery
The outlook for most cats with inflammatory polyps is good, especially when the mass can be removed and the cat is otherwise healthy. Many cats breathe more comfortably, eat better, and have fewer ear signs soon after treatment. VCA notes that most cats enjoy a relatively normal quality of life following standard polyp removal surgery. That is encouraging, but recovery still depends on where the polyp started, whether the middle ear is involved, and whether the entire stalk was addressed.
Recurrence is the main long-term concern. Merck notes that regrowth is common if the entire polyp and stalk are not completely removed. This is one reason some cats do well after traction removal while others need a second procedure or referral surgery. Cats with recurrent disease, persistent middle ear changes, or neurologic signs may benefit from a more advanced surgical plan rather than repeating the same limited approach.
Short-term recovery varies with the procedure. After simple removal, many cats go home the same day or after a short stay, with pain control and recheck instructions. After more involved surgery such as ventral bulla osteotomy, recovery may take longer and temporary complications can occur, including balance changes, Horner syndrome, or facial nerve effects. Your vet can explain which risks are most relevant for your cat's anatomy and procedure.
At home, monitor breathing, appetite, swallowing, activity, and any return of ear or nasal signs. Keep all follow-up visits, and ask whether histopathology confirmed an inflammatory polyp. If signs return weeks or months later, that does not always mean an emergency, but it does mean your vet should reassess the area and discuss whether recurrence, residual disease, or another diagnosis is more likely.
Questions to Ask Your Vet
Bring these questions to your vet appointment to get the most out of your visit.
- Where do you think the polyp starts: middle ear, auditory tube, or throat area? The site of origin affects recurrence risk, imaging needs, and which treatment options make sense.
- Does my cat need sedation, anesthesia, imaging, or endoscopy to confirm the diagnosis? This helps you understand how much testing is needed before treatment and what the workup may cost.
- Is traction removal a reasonable first step, or do you recommend referral surgery now? Some cats can start with a less invasive approach, while others are better served by a more definitive plan.
- What is the chance of recurrence with the option you recommend? Recurrence is common in some cases, so it is important to compare short-term and long-term plans.
- Will you send the tissue for histopathology? Lab confirmation helps distinguish an inflammatory polyp from other masses that can look similar.
- Are there signs of middle ear disease or neurologic involvement? Head tilt, Horner syndrome, and balance changes can point to deeper disease that may change treatment.
- What should I watch for at home after the procedure? Knowing the expected recovery signs helps you spot breathing trouble, pain, or complications early.
- Can you give me a written estimate for conservative, standard, and advanced care options? A clear cost range helps you make a plan that fits your cat's needs and your budget.
FAQ
Are inflammatory polyps in cats cancer?
Usually no. Inflammatory polyps are considered benign, meaning noncancerous. Even so, they can still cause serious breathing, swallowing, and ear problems because of where they grow. Your vet may recommend histopathology after removal to confirm the diagnosis.
Do inflammatory polyps go away on their own?
They usually do not resolve on their own once they are large enough to cause signs. Because they can obstruct airflow or affect the middle ear, treatment often involves removing the polyp rather than waiting.
Why does my cat sound congested or snore while awake?
A nasopharyngeal polyp can partially block the space behind the nose and create a low, noisy breathing sound called stertor. Other conditions can cause similar sounds, so your vet needs to examine the airway and ears to find the cause.
Can a cat have both ear signs and breathing signs from the same polyp?
Yes. Some inflammatory polyps arise from the middle ear and extend toward the back of the throat. That can lead to a mix of head tilt, ear scratching, or discharge along with sneezing, gagging, or noisy breathing.
Will the polyp come back after surgery?
It can. Recurrence is more likely if the entire stalk and tissue of origin are not removed. Your vet may discuss a less invasive first procedure versus a more advanced surgery if recurrence risk is high.
Is surgery always needed?
Most symptomatic cats need some form of removal because the mass itself is the problem. The exact procedure varies. Some cats can have traction removal, while others need advanced imaging and specialty surgery. Your vet can help match the plan to the case.
How much does treatment usually cost?
In the US in 2026, a straightforward workup and removal may fall around a few hundred to about $1,200, while a more complete workup with anesthesia and imaging may run roughly $800 to $2,500. Referral-level care with CT and ventral bulla osteotomy can reach about $2,500 to $4,500 or more depending on region and complexity.
