Nasopharyngeal Polyps in Cats: Symptoms & Surgery
- Nasopharyngeal polyps are benign inflammatory growths that usually develop near the middle ear or auditory tube and extend into the back of the nose or throat.
- They are seen most often in kittens and young cats, but older cats can be affected too.
- Common signs include noisy breathing, sneezing, nasal discharge, gagging, trouble swallowing, reverse sneezing, and sometimes head tilt or ear problems.
- Diagnosis often requires sedation or anesthesia so your vet can examine the nasopharynx and ears thoroughly. X-rays, CT, or endoscopy may be recommended in some cats.
- Treatment usually involves removal under anesthesia. Simple traction-avulsion is less invasive but can recur, while ventral bulla surgery is more involved and may lower recurrence in selected cases.
What Is Nasopharyngeal Polyps?
Nasopharyngeal polyps are noncancerous inflammatory growths found in the back of a cat's nose and throat area. In many cats, they appear to arise from tissue connected to the middle ear, auditory tube, or nearby throat lining, then extend into the nasopharynx where they can partly block airflow. Even though they are benign, they can still cause significant breathing, swallowing, and ear-related problems.
These polyps are reported most often in kittens and young cats, especially around the first year of life, but they are not limited to that age group. A cat may sound congested for weeks or months before the cause is identified. Because the mass sits deep in the throat, pet parents may mistake it for a lingering upper respiratory infection.
When a polyp grows large enough, it can create stertor or loud, snoring-type breathing, trigger sneezing, or make swallowing uncomfortable. Some cats also show ear signs because the same disease process can involve the middle ear. That overlap is one reason your vet may examine both the throat and the ears when a polyp is suspected.
Symptoms of Nasopharyngeal Polyps
- Noisy breathing or snoring sounds
- Sneezing
- Nasal discharge
- Reverse sneezing or gagging
- Difficulty swallowing
- Open-mouth breathing or breathing effort
- Head tilt, ear scratching, or recurrent ear infection signs
- Voice change or reduced activity
See your vet immediately if your cat has open-mouth breathing, blue or gray gums, severe breathing effort, collapse, or cannot eat or drink. Those signs can mean the airway is significantly affected.
For milder signs, it is still worth scheduling an exam soon. Chronic noisy breathing, repeated sneezing, or a "stuffy" sound that does not improve with time should not be assumed to be a routine cold. A deep throat or middle-ear polyp can look very similar from home.
What Causes Nasopharyngeal Polyps?
The exact cause is not fully understood. Current veterinary sources describe nasopharyngeal polyps as inflammatory growths, and proposed causes include chronic inflammation, congenital factors, genetics, and infectious triggers. Some specialists suspect that prior upper respiratory viral disease may contribute in at least some cats.
Cornell notes that these polyps may be linked to inflammatory changes after respiratory viral infection, while Merck states that long-term inflammation is a possible factor. That means a cat may have had earlier airway irritation or infection, but there is usually no single event that clearly explains why the polyp formed.
Importantly, this is not something a pet parent causes through routine care. Polyps are also different from cancer. They are benign, but their location can still make them medically important because they can obstruct airflow or involve the middle ear.
How Is Nasopharyngeal Polyps Diagnosed?
Diagnosis starts with a careful history and physical exam. Your vet will listen to your cat's breathing, ask about sneezing, swallowing, and ear signs, and look for clues that the problem is coming from the nasopharynx, middle ear, or both. Because these polyps sit deep in the throat, they are often not visible during a routine awake exam.
Many cats need sedation or general anesthesia so your vet can lift the soft palate, inspect the nasopharynx, and perform an otoscopic ear exam. In some cases, the polyp can be directly seen as a smooth pink mass. If the diagnosis is still uncertain, your vet may recommend skull radiographs, CT, MRI, or endoscopy/video otoscopy to look for disease in the tympanic bulla or to rule out other causes of chronic nasal signs.
Definitive confirmation is often made by histopathology after removal. That step helps distinguish an inflammatory polyp from other masses, including less common tumors or fungal disease. Your vet may also recommend additional testing if your cat's signs could fit other conditions such as chronic rhinitis, foreign material, or nasal infection.
Treatment Options for Nasopharyngeal Polyps
Spectrum of Care means you have options. Here are treatment tiers at different price points.
Budget-Conscious Care
- Exam and sedation/anesthesia for oral and ear evaluation

- Possible short course of steroid and/or antibiotic based on your vet's findings
Recommended Standard Treatment
- Full exam with sedation or anesthesia
- Polyp removal under anesthesia
- Histopathology of removed tissue
- Ear exam and flushing if indicated
- Pre-anesthetic lab work and monitoring
- Post-op medications and recheck visit
Advanced / Critical Care
- Referral surgery or specialty care
- CT imaging and/or video otoscopy when anatomy is unclear
- Ventral bulla osteotomy for recurrent, severe, or middle-ear-associated disease
- Advanced anesthesia monitoring
- Histopathology and culture when indicated
- Hospitalization and neurologic/ear complication monitoring

Questions to Ask Your Vet About Nasopharyngeal Polyps
Bring these questions to your vet appointment to get the most out of your visit.
- Based on my cat's exam, does this look more like a nasopharyngeal polyp, chronic infection, or another type of mass?
- Does my cat need sedation or anesthesia to confirm the diagnosis safely?
- Would basic X-rays be enough, or would CT, endoscopy, or referral change the plan?
- Is traction-avulsion a reasonable first option for my cat, and what is the recurrence risk in this specific case?
- When would ventral bulla surgery be worth considering instead of a less invasive removal?
- What complications should I watch for after surgery, especially changes in balance, pupils, facial movement, or appetite?
- Will the removed tissue be sent for histopathology, and what information will that give us?
- What follow-up schedule do you recommend if my cat's breathing improves but the signs return later?
How to Prevent Nasopharyngeal Polyps
There is no proven way to fully prevent nasopharyngeal polyps in cats. Because the exact cause remains unclear, prevention is mostly about reducing airway and ear inflammation where possible and getting persistent signs checked early.
Helpful steps include keeping up with routine veterinary visits, addressing chronic sneezing, nasal discharge, ear infections, or head shaking promptly, and following your vet's treatment plan if your cat has recurring upper respiratory disease. Good indoor air quality may also help some cats feel more comfortable, especially if smoke, dust, or strong fragrances seem to worsen congestion.
If your cat has already had a polyp removed, the main goal becomes early detection of recurrence. Watch for return of noisy breathing, gagging, swallowing trouble, or ear-related signs. A quick recheck can sometimes catch regrowth before the obstruction becomes more serious.
