Nasopharyngeal Polyps in Cats: Signs, Treatment and Recurrence

By Dr Duncan Houston

A cat that starts snoring loudly while awake, breathing with a constant snorting sound or developing repeated problems in one ear may have more than an ordinary respiratory infection.

Feline inflammatory polyps are benign growths that commonly arise from the lining of the middle ear, auditory tube or throat. They may extend into the nasopharynx behind the soft palate or grow outward through the eardrum into the external ear canal. Although they are not cancerous, a large polyp can obstruct breathing, interfere with swallowing, cause chronic ear disease or affect balance and facial nerves. (Merck Veterinary Manual)

The important question is not simply whether a cat has a polyp. It is where the polyp begins, how much middle-ear disease is present and whether simple removal will be enough to prevent it returning.

Quick Answer

Nasopharyngeal polyps are non-cancerous inflammatory masses most commonly seen in kittens and young adult cats. Typical signs include persistent snoring or snorting while awake, nasal discharge, sneezing, gagging, difficulty swallowing, recurrent one-sided ear infections, head tilt or balance problems.

Treatment requires removal of the polyp. Traction avulsion is less invasive but has a higher recurrence risk, while ventral bulla osteotomy removes the polyp’s middle-ear origin and provides better long-term control in selected cats. Open-mouth breathing, severe respiratory effort, blue or grey gums, collapse or inability to swallow requires emergency veterinary care. (Merck Veterinary Manual)

Nasopharyngeal Polyps at a Glance

Question	Practical answer
What is a nasopharyngeal polyp?	A benign inflammatory mass affecting the middle ear, auditory tube, throat or external ear canal
Which cats are most commonly affected?	Juvenile and young adult cats, usually between 3 months and 5 years
What does it sound like?	Persistent low-pitched snorting, stertor or loud snoring while awake
Can it affect the ears?	Yes. It may cause discharge, scratching, head shaking, head tilt or balance problems
Is it cancer?	Usually no, but histopathology should confirm the diagnosis
Can antibiotics remove it?	No. Antibiotics may treat secondary infection but cannot remove the mass
What is traction avulsion?	Pulling an accessible polyp free under general anaesthesia
What is ventral bulla osteotomy?	Surgery that opens the middle ear and removes the polyp’s base and inflamed tissue
Can the polyp return?	Yes, particularly after incomplete traction removal
Is the prognosis good?	Usually excellent when the polyp is properly removed

Inflammatory polyps are most common in cats between 3 months and 5 years of age, with no recognised sex or breed predisposition. Older cats can also be affected, but cancer and other diseases become more important alternatives in that age group. (Merck Veterinary Manual)

What Is a Nasopharyngeal Polyp?

A nasopharyngeal polyp is a smooth, pink, fleshy inflammatory growth extending into the upper throat behind the soft palate.

Many feline inflammatory polyps originate within the tympanic bulla, the bony chamber forming the middle ear. From there, the polyp may grow in one of two directions:

1. Through the auditory tube into the nasopharynx

2. Through the eardrum into the external ear canal

Some polyps appear to arise from the auditory tube or pharyngeal lining itself. Their eventual signs depend on which direction they grow and which structures they compress. (Merck Veterinary Manual)

The terms nasopharyngeal polyp, aural polyp, oropharyngeal polyp and inflammatory polyp may all describe parts of the same disease process.

Benign Does Not Mean Harmless

These polyps do not usually invade or spread through the body like malignant cancer.

They can still cause serious disease by:

• Blocking airflow through the nasopharynx

• Preventing normal drainage from the middle ear

• Encouraging bacterial infection

• Interfering with swallowing

• Damaging nerves controlling the eye and face

• Affecting the inner ear and balance system

• Causing progressive weight loss or respiratory distress

A benign growth occupying the wrong few millimetres can be a substantial problem in a cat’s narrow upper airway.

What Causes Nasopharyngeal Polyps?

The exact cause remains unknown.

Congenital development, inherited susceptibility, chronic inflammation and infection have all been proposed. However, investigations have not established a clear causal relationship with feline herpesvirus, feline calicivirus, Mycoplasma, Bartonella or Chlamydia felis. Herpesvirus and calicivirus have not been consistently identified within polyp tissue. There is also no recognised association with feline leukaemia virus or feline immunodeficiency virus status. (Merck Veterinary Manual)

This means it is inaccurate to say that feline calicivirus or one previous ear infection directly causes every polyp.

Chronic inflammation may still contribute, but the precise sequence remains uncertain.

Can Polyps Be Prevented?

There is no proven method for preventing feline inflammatory polyps because their underlying cause has not been established.

Prompt investigation of persistent upper-airway noise, unilateral ear disease and recurring infections may allow earlier diagnosis, but treating every respiratory infection does not guarantee that a polyp will never develop. (Merck Veterinary Manual)

What Are the Signs of a Nasopharyngeal Polyp?

The signs depend on whether the polyp extends primarily into the throat, external ear or middle and inner ear.

Nasopharyngeal and Upper-Airway Signs

A polyp behind the soft palate may cause:

• Persistent snoring or snorting while awake

• Stertor, a low-pitched noisy breathing sound

• Nasal obstruction

• Reduced airflow through one or both nostrils

• Sneezing

• Clear, mucoid or occasionally blood-tinged nasal discharge

• Gagging

• Repeated swallowing

• Difficulty swallowing

• Coughing or retching during eating

• Reduced appetite

• Weight loss

• Breathing difficulty

A large polyp may physically push the soft palate downward and substantially narrow the upper airway. (Merck Veterinary Manual)

Normal Sleeping Snoring Versus Suspicious Stertor

Occasional soft snoring during deep sleep does not automatically mean a cat has a polyp.

The sound becomes more suspicious when it:

• Occurs while the cat is awake

• Is new or becoming louder

• Is present during every breath

• Is accompanied by nasal discharge

• Worsens during eating or activity

• Causes gagging or swallowing difficulty

• Persists despite treatment for an upper respiratory infection

The mistake I see most often is describing chronic awake stertor as a quirky snore for months before the cat is properly examined.

External Ear Signs

When a polyp extends through the eardrum into the external ear canal, signs may include:

• Head shaking

• Scratching one ear

• Recurrent unilateral otitis

• Brown, yellow, bloody or purulent ear discharge

• Foul odour from one ear

• Pain when the ear is handled

• A visible pink mass within the canal

• Reduced hearing

• An aural haematoma from repeated head shaking

Persistent one-sided ear disease that repeatedly returns after medication should raise concern for a polyp, foreign body, middle-ear disease or tumour rather than being treated indefinitely as uncomplicated otitis externa. (Merck Veterinary Manual)

Middle and Inner Ear Signs

A polyp or associated inflammation within the middle ear may affect the nerves controlling the eye, face and balance system.

Possible signs include:

• Head tilt

• Falling or leaning to one side

• Ataxia or wobbliness

• Circling

• Nystagmus, meaning rapid involuntary eye movements

• Facial nerve paralysis

• Reduced blinking

• Drooping of the lip or ear

• Horner syndrome

Horner syndrome usually causes:

• A smaller pupil on the affected side

• A drooping upper eyelid

• A raised third eyelid

• An eye that appears slightly sunken

These signs can occur before treatment because of the polyp itself or temporarily after polyp removal because sensitive nerves run along the middle-ear wall. (Merck Veterinary Manual)

How Worried Should You Be?

Lower Immediate Risk

Your cat:

• Snores only occasionally while deeply asleep

• Breathes normally while awake

• Eats and swallows normally

• Has no nasal or ear discharge

• Remains active and comfortable

What it may mean: Normal sleeping noise, mild congestion or facial anatomy may be responsible.

What to do: Record a video and monitor. Arrange a routine examination if the sound is new, persistent or becoming louder.

Moderate Concern

Your cat has:

• Persistent snorting or noisy breathing while awake

• Recurrent sneezing

• One-sided ear discharge

• Repeated head shaking

• A chronic upper respiratory problem that does not fully resolve

• Normal breathing effort at rest

What it may mean: A nasopharyngeal polyp, chronic rhinitis, middle-ear disease or another obstructive condition is possible.

What to do: Arrange a veterinary examination within the next few days. Sedated oral and ear examination may be required.

High Concern

Your cat has:

• Difficulty swallowing

• Reduced food intake

• Weight loss

• Head tilt

• Nystagmus

• Wobbliness

• Facial asymmetry

• Thick or bloody discharge

• Increasing respiratory noise

What it may mean: Significant obstruction, middle-ear involvement or neurological complications may be present.

What to do: Seek same-day veterinary assessment. Advanced imaging and referral may be appropriate.

Critical

Your cat has:

• Open-mouth or laboured breathing

• Pronounced abdominal breathing effort

• Blue, grey or very pale gums

• Collapse

• Severe weakness

• Inability to swallow

• Choking or repeated aspiration

• Minimal responsiveness

What it may mean: Severe airway obstruction or oxygen deprivation is developing.

What to do: Attend an emergency veterinary hospital immediately. Open-mouth breathing and abnormal gum colour indicate potentially severe oxygen loss. (Merck Veterinary Manual)

When Is This an Emergency?

Seek emergency veterinary care immediately when your cat develops:

• Open-mouth breathing

• Severe effort while inhaling

• Neck extension while trying to breathe

• Blue or grey gums

• Collapse

• Inability to swallow saliva

• Repeated choking or aspiration

• Profound weakness

• Rapid deterioration over several hours

• Severe vestibular signs causing repeated falling

• Inability to eat or drink

Keep the cat as calm as possible during transport. Stress and struggling increase oxygen demand and may worsen a partially obstructed airway.

Do not force food, water or oral medication into a cat that is having difficulty breathing or swallowing.

What Else Can Look Like a Nasopharyngeal Polyp?

A polyp cannot always be diagnosed from its sound or appearance alone.

Possible condition	Important clues
Chronic viral rhinitis	Long-standing sneezing and nasal discharge, sometimes affecting both sides
Secondary bacterial rhinitis	Thick discharge, worsening after viral disease
Nasopharyngeal stenosis	Narrowing caused by scar tissue, often after inflammation or trauma
Nasal foreign body	Sudden severe sneezing, often with unilateral discharge
Cryptococcosis or other fungal disease	Nasal swelling, chronic discharge, skin lesions or neurological signs
Nasal or nasopharyngeal cancer	More concerning in middle-aged and older cats, especially with bleeding or facial distortion
Lymphoma	Nasal obstruction, discharge, weight loss or systemic signs
Ear canal tumour	Persistent unilateral otitis, bleeding or a mass in an older cat
Otitis media or interna	Head tilt, pain, discharge and balance abnormalities without a visible polyp
Laryngeal disease	Higher-pitched noisy breathing, voice change or inspiratory distress
Dental or oral disease	Drooling, difficulty eating, facial swelling or oral pain

Fungal rhinitis, foreign material, chronic inflammatory disease and neoplasia can all produce chronic nasal signs. Middle-aged and older cats with persistent unilateral ear disease are also more likely than young cats to have an ear canal tumour rather than an inflammatory polyp. (Vca)

Why Histopathology Matters

A smooth pink mass in a young cat is strongly suggestive of an inflammatory polyp, but appearance is not definitive.

Removed tissue should be submitted for histopathology, particularly when:

• The cat is older

• The mass is irregular, ulcerated or bleeding

• The tissue is unusually firm

• There is bone destruction

• The lesion has returned repeatedly

• The diagnosis is uncertain

• The response to treatment is atypical

Histological examination remains the definitive method of confirming an inflammatory polyp and excluding cancer or another lesion. (Merck Veterinary Manual)

What To Do Right Now

1. Record the Breathing Sound

Take short videos while your cat is:

• Resting quietly

• Awake

• Eating

• Sleeping

Record whether the sound is present during inhalation, exhalation or both.

Do not provoke exercise or stress to make the noise more dramatic.

2. Observe Eating and Swallowing

Watch for:

• Gagging

• Food falling from the mouth

• Repeated swallowing

• Coughing during meals

• Regurgitation

• Reduced appetite

• Weight loss

• Difficulty drinking

These signs increase the urgency because the mass may be interfering with the pharynx or creating an aspiration risk.

3. Check for One-Sided Ear Signs

Compare both ears for:

• Discharge

• Odour

• Scratching

• Head shaking

• Pain

• Head tilt

Do not insert cotton buds or instruments into the ear canal.

4. Avoid Unprescribed Ear Cleaners

The eardrum may be ruptured or displaced, allowing cleaning solution to enter the middle ear.

Some products can irritate middle and inner-ear structures and worsen head tilt, nystagmus or balance problems when the eardrum is damaged. (Vca)

5. Do Not Attempt To Pull the Mass Out

Polyp removal requires general anaesthesia, airway protection and proper assessment of the stalk and middle ear.

Pulling an accessible piece at home can cause:

• Bleeding

• Aspiration

• Airway swelling

• Incomplete removal

• Nerve injury

• Rapid recurrence

6. Arrange a Veterinary Examination

Tell the clinic if your cat has:

• Noisy breathing

• Difficulty swallowing

• Head tilt

• Nystagmus

• Repeated ear disease

• Previous polyp treatment

• A history of respiratory distress

This allows the team to plan sedation, airway management, imaging or referral safely.

How Are Nasopharyngeal Polyps Diagnosed?

Physical Examination

The veterinarian will assess:

• Breathing pattern and airway noise

• Nasal airflow

• Mouth and throat

• Both ear canals

• Eardrums

• Facial symmetry

• Eye position and pupil size

• Gait and balance

• Ability to swallow

Both ears and the nasopharynx should be examined because a middle-ear polyp can extend in more than one direction. (Merck Veterinary Manual)

Examination Under Sedation or Anaesthesia

Nasopharyngeal polyps are often hidden above the soft palate and cannot be seen during an ordinary conscious mouth examination.

Under general anaesthesia, the veterinarian may:

1. Protect the airway with an endotracheal tube

2. Retract the soft palate forward

3. Examine behind the palate

4. Use a mirror or retroflexed endoscope

5. Inspect both ear canals with an otoscope or video otoscope

A large polyp may become visible when the soft palate is retracted. Smaller or more deeply positioned lesions may require endoscopy or imaging. (Merck Veterinary Manual)

Otoscopy and Video Otoscopy

Otoscopy may reveal:

• A pink mass in the external ear canal

• Purulent material

• A ruptured or distorted eardrum

• A bulging or discoloured eardrum

• Chronic canal narrowing

Flushing and suction may be required before the mass can be visualised. Video otoscopy provides magnification and may also allow minimally invasive treatment in suitable cases. (Merck Veterinary Manual)

Radiographs

Skull radiographs may show increased opacity, thickening or other changes within the affected tympanic bulla.

Their limitations include overlapping skull structures and lower sensitivity for small or complex lesions.

CT or MRI

CT is often the most useful imaging method for determining:

• Whether the middle ear is involved

• Which bulla is affected

• The size and direction of the polyp

• Whether both ears are involved

• Whether chronic bone change is present

• Whether a different type of mass is more likely

• Which surgical approach is appropriate

MRI may provide additional information about soft tissue and neurological structures. Advanced imaging is particularly valuable in recurrent cases, cats with neurological signs and cats whose mass cannot be visualised directly. (Merck Veterinary Manual)

How Are Nasopharyngeal Polyps Treated?

The treatment is physical removal of the polyp.

Antibiotics, steroids and decongestants may temporarily improve secondary inflammation or infection, but they do not eliminate the mass.

The main removal options are:

1. Traction avulsion

2. Ventral bulla osteotomy

3. Specialist endoscopic techniques

The appropriate choice depends on where the polyp is located, whether the middle ear is affected and whether the cat has been treated previously.

What Is Traction Avulsion?

Traction avulsion is the simplest and least invasive removal method for an accessible polyp.

With the cat under general anaesthesia, the surgeon grasps the polyp through the mouth or external ear canal and applies slow, steady traction. Ideally, the entire polyp and its narrow stalk separate from their attachment. (Merck Veterinary Manual)

Advantages

Traction avulsion:

• Requires no external surgical incision

• Is usually quicker than bulla surgery

• Often provides immediate improvement in breathing

• May be appropriate as first-line treatment for a nasopharyngeal-only polyp

• Usually has a shorter initial recovery

Limitations

The base of the polyp frequently remains inside the middle ear.

If inflammatory tissue and the attachment site remain, the polyp can regrow. Published recurrence estimates following traction alone vary, but a practical range is approximately 15% to 50%, with some surgical guidance quoting 30% to 50%. (Merck Veterinary Manual)

In one review of 37 cats, 13 of 22 cats with long-term follow-up had no recurrence after traction alone. Cats with only nasopharyngeal involvement were substantially more likely to remain controlled than cats with aural or middle-ear disease. (ResearchGate)

When Is Traction Most Reasonable?

It may be a reasonable first option when:

• The polyp is clearly visible and accessible

• Signs are predominantly nasopharyngeal

• Imaging shows limited middle-ear disease

• The cat has not had previous recurrence

• Owners understand that further surgery may eventually be needed

What Is a Ventral Bulla Osteotomy?

A ventral bulla osteotomy, or VBO, is surgery performed through the underside of the neck to open the tympanic bulla.

The surgeon removes:

• The polyp’s attachment

• Abnormal inflammatory tissue

• Secretions or infected material

• Diseased lining from the middle-ear compartments

Because the origin is treated more completely, recurrence is substantially lower than after traction alone. ACVS reports recurrence rates below approximately 2% to 10% following traction combined with VBO, compared with 30% to 50% after traction alone. (American College of Veterinary Surgeons)

When Is VBO More Likely To Be Recommended?

VBO may be advised when:

• CT shows substantial middle-ear disease

• The polyp extends into the external ear canal

• Chronic otitis is present

• The ear canal has become narrowed

• Neurological signs are present

• The polyp has returned after traction

• The stalk cannot be removed completely

• Long-term recurrence control is the priority

Some surgeons consider VBO the treatment of choice for most middle-ear inflammatory polyps, while others initially use traction in carefully selected cases. (Merck Veterinary Manual)

What Are the Disadvantages?

VBO is more invasive and involves structures close to important nerves and the inner ear.

Possible postoperative complications include:

• Horner syndrome

• Head tilt

• Ataxia

• Nystagmus

• Facial nerve dysfunction

• Reduced blinking

• Temporary hearing changes

• Pain

• Surgical-site infection

These complications are relatively common but are usually temporary. (American College of Veterinary Surgeons)

Are Minimally Invasive Endoscopic Options Available?

Some referral centres offer video-assisted or per-endoscopic trans-tympanic techniques that allow the surgeon to enter the middle ear through the ear canal and eardrum.

In one case series involving 37 cats, per-endoscopic trans-tympanic traction achieved clinical resolution in 94% of cats during an average follow-up of approximately 19 months. Recurrence occurred in 13.5%, while immediate postoperative Horner syndrome occurred in 8% and resolved within several weeks. (PubMed)

This approach may reduce neurological complications compared with conventional VBO in selected cases, but it requires:

• Specialist equipment

• Appropriate anatomy

• An experienced operator

• Careful imaging and case selection

It is not available at every hospital and is not suitable for every polyp.

Do Steroids Prevent Recurrence?

Corticosteroids are sometimes prescribed after traction removal to suppress residual inflammation and reduce regrowth.

Retrospective reports suggest a possible benefit. In one older series, none of the cats receiving prednisolone after traction developed recurrence. However, that study was not a randomised controlled trial, and the number of treated cats was limited. A later endoscopic series also found that several recurrent cases had not received postoperative corticosteroids, but recurrence still occurred in some cats that had. (BVA Journals)

The practical interpretation is:

• Steroids may reduce inflammation and possibly recurrence after traction.

• They do not guarantee that the polyp will not return.

• They cannot replace complete removal of a persistent middle-ear attachment.

• The drug, dose and duration should be determined by the surgeon.

Topical steroid treatment within the bulla has also been used for several weeks after selected procedures. (Merck Veterinary Manual)

Does Every Cat Need Antibiotics?

No.

Antibiotics are appropriate when bacterial infection is present or strongly suspected, particularly when the middle ear contains purulent material.

Ideally, material from the bulla or ear should be submitted for bacterial culture and susceptibility testing. Treatment can then be selected according to the organism identified rather than prescribed automatically. (Merck Veterinary Manual)

Antibiotics cannot remove an inflammatory polyp and should not be used repeatedly as the only treatment for persistent obstruction.

What Happens After Surgery?

Postoperative treatment may include:

• Pain relief

• Anti-inflammatory medication

• Culture-directed antibiotics

• An Elizabethan or soft protective collar

• Temporary feeding of soft or wet food

• Eye lubrication if blinking is impaired

• Short-term activity restriction

• Follow-up ear and neurological examinations

Most cats recover rapidly and breathe more quietly soon after the obstructing mass has been removed. Appetite should be monitored closely, particularly following VBO or when swallowing was affected before surgery. (American College of Veterinary Surgeons)

Contact the surgical team promptly if the cat:

• Does not eat

• Repeatedly vomits

• Cannot swallow

• Develops worsening respiratory noise

• Has significant wound swelling or discharge

• Cannot stand

• Develops severe or worsening neurological signs

• Cannot close one eye properly

What Is Horner Syndrome After Polyp Surgery?

Horner syndrome develops when sympathetic nerves running through the middle ear are stretched or damaged.

Signs on the affected side include:

• Small pupil

• Drooping upper eyelid

• Elevated third eyelid

• Sunken appearance of the eye

ACVS notes that Horner syndrome may occur in around 80% of cats following conventional VBO. The precise rate varies between procedures and studies. It is usually temporary and generally does not affect vision. Most cats improve over several weeks, although occasional cases take longer. (American College of Veterinary Surgeons)

When Is Eye Treatment Needed?

If facial nerve dysfunction prevents the cat from blinking normally, the cornea may dry out.

The veterinary team may prescribe:

• Lubricating eye drops or ointment

• Corneal monitoring

• Additional eye protection

Reduced blinking should not be ignored simply because it developed after expected ear surgery.

Can Balance Problems Occur After Surgery?

Yes.

The inner ear lies beside the tympanic bulla. Manipulation, inflammation or temporary injury may cause:

• Head tilt

• Ataxia

• Falling

• Nystagmus

• Nausea

• Reduced appetite

These signs are usually temporary but can significantly affect the cat’s comfort and ability to eat, drink or use the litter box. A quiet, padded and easily accessible recovery area is important. (American College of Veterinary Surgeons)

Persistent or worsening vestibular signs should be reassessed rather than assumed to be an unavoidable part of recovery.

Can Nasopharyngeal Polyps Return?

Yes.

Recurrence depends largely on how completely the polyp’s stalk and origin are removed.

Treatment	Approximate recurrence pattern
Traction alone	Commonly reported around 15% to 50%
Traction plus VBO	Usually below approximately 2% to 10%
Per-endoscopic trans-tympanic traction	13.5% in one 37-cat case series

These figures come from different studies and patient populations, so they should not be treated as exact predictions for one individual cat. (Merck Veterinary Manual)

Signs That a Polyp May Have Returned

Watch for:

• Return of stertor or snoring while awake

• Recurrent nasal discharge

• Renewed gagging or swallowing difficulty

• Head shaking

• Ear discharge

• Head tilt

• Wobbliness

• Reduced hearing

Recurrence often occurs within the first several months, but delayed recurrence and persistent middle-ear disease can appear considerably later. Long-term monitoring remains worthwhile. (Sage Journals)

What Is the Prognosis?

The overall prognosis is excellent for most cats.

Cats with accessible nasopharyngeal polyps and limited middle-ear disease may recover completely after traction removal. Cats undergoing VBO generally have a lower recurrence risk, although temporary neurological complications are more common.

ACVS reports that Horner syndrome and postoperative balance problems usually resolve within approximately one month. Some cats may retain a mild head tilt, intermittent balance abnormalities or reduced hearing, particularly when substantial middle or inner-ear disease existed before treatment. (American College of Veterinary Surgeons)

The prognosis becomes less predictable when:

• The cat is older

• Histopathology identifies cancer rather than a polyp

• Chronic middle-ear infection is present

• Bone destruction is identified

• The polyp has returned several times

• Neurological damage is severe or longstanding

• Both ears are affected

Common Mistakes With Feline Polyps

Assuming Every Snore Is Normal

Persistent low-pitched breathing noise while awake deserves investigation.

Repeatedly Treating an Upper Respiratory Infection

Antibiotics may temporarily reduce discharge while the underlying obstruction remains.

Treating One-Sided Otitis Without Looking Deeper

Recurring unilateral ear disease often has an underlying structural cause.

Using Ear Cleaner Without Knowing Whether the Eardrum Is Intact

Middle-ear exposure can worsen pain and vestibular signs.

Removing the Visible Polyp Without Discussing the Middle Ear

The part visible in the throat or ear canal may be only the end of a much longer stalk.

Assuming Steroids Guarantee No Recurrence

They may help after traction but cannot compensate for persistent polyp tissue.

Failing To Submit the Mass for Histopathology

This is particularly important in older cats or when the tissue looks atypical.

Waiting for Severe Respiratory Distress

Smaller polyps are generally easier to investigate and treat before airway obstruction becomes advanced.

Can Nasopharyngeal Polyps Go Away Without Surgery?

Spontaneous resolution has been reported in an isolated case, but this appears unusual and cannot be predicted. Surgical removal remains the accepted treatment for a cat with persistent clinical signs or significant obstruction. (PubMed Central (PMC))

Waiting is particularly inappropriate when the cat has:

• Difficulty breathing

• Difficulty swallowing

• Weight loss

• Recurrent otitis

• Vestibular signs

• Progressive symptoms

Frequently Asked Questions

Is a nasopharyngeal polyp cancer?

Usually not. Feline inflammatory polyps are benign, non-neoplastic masses. Histopathology is still recommended because other benign and malignant masses can look similar. (Merck Veterinary Manual)

Does every cat with a polyp need ventral bulla osteotomy?

No. Traction avulsion may be reasonable for a first-time, accessible nasopharyngeal polyp with limited middle-ear disease. VBO is more strongly considered when substantial bulla disease, aural extension, chronic infection or recurrence is present. (Merck Veterinary Manual)

How quickly will my cat breathe better after removal?

Many cats show immediate or rapid improvement once the obstructing mass is removed. Recovery may be slower when there is extensive swelling, infection, neurological disease or another respiratory condition.

Is Horner syndrome after surgery permanent?

Usually not. It is common after middle-ear surgery but generally improves over several weeks. A small number of cats may have longer-lasting signs. (American College of Veterinary Surgeons)

Can a polyp grow back years later?

Yes. Most recurrence is recognised within months, but delayed regrowth or persistent middle-ear disease can occur. Any return of noisy breathing, ear discharge or head tilt deserves reassessment. (Sage Journals)

Final Thoughts

Nasopharyngeal polyps are benign, but their location can make them far more serious than the word benign suggests.

The most important points are:

1. Polyps commonly arise from the middle ear, auditory tube or pharyngeal lining.

2. Young cats are affected most often, but cats of any age can develop them.

3. Persistent snorting or snoring while awake is not normal.

4. Recurrent one-sided ear disease may be caused by an underlying polyp.

5. Head tilt, nystagmus and wobbliness suggest middle or inner-ear involvement.

6. The cause is unknown, and a direct viral cause has not been proven.

7. Examination often requires sedation or general anaesthesia.

8. Both ears and the nasopharynx should be assessed.

9. CT is particularly useful for identifying middle-ear disease and planning surgery.

10. Histopathology should confirm that the mass is an inflammatory polyp.

11. Traction avulsion is less invasive but has a higher recurrence risk.

12. Ventral bulla osteotomy provides better control when the middle ear is involved.

13. Horner syndrome and vestibular signs are common postoperative complications but are usually temporary.

14. Antibiotics treat secondary infection, not the polyp itself.

15. Open-mouth breathing, abnormal gum colour or collapse is an emergency.

The mistake that causes the greatest harm is repeatedly treating the discharge or ear infection without finding the structure causing it. Once the underlying polyp is identified and properly removed, most cats have an excellent chance of breathing, eating and living normally again.

ASK A VET™ can help you organise videos of the breathing noise, ear-treatment history, imaging findings and surgical questions while you work directly with your cat’s attending veterinarian or veterinary surgeon. A cat with open-mouth breathing, severe respiratory effort, blue or grey gums, collapse or inability to swallow still requires immediate hands-on emergency care.
