# Ear Polyps in Cats: Signs, Diagnosis, Surgery, and Recurrence ## Key Takeaways - Feline inflammatory polyps are benign, stalked masses originating from the middle ear, auditory tube, or pharyngeal lining, potentially extending into the ear canal or nasopharynx. - Clinical signs are variable, ranging from recurrent otitis, head shaking, and ear discharge to neurological deficits (head tilt, balance issues, Horner's syndrome) and upper airway obstruction (noisy breathing, dysphagia) depending on the polyp's location. - Diagnosis necessitates veterinary examination under sedation or anesthesia, including otoscopy, oral inspection, and often advanced imaging like CT or MRI to assess extent and origin, with histopathology being definitive for ruling out neoplasia. - Treatment options include traction avulsion for accessible polyps or ventral bulla osteotomy for complete removal of the polyp's origin within the tympanic bulla, especially in cases of recurrence or extensive middle ear involvement. - Recurrence is a significant concern, particularly if the polyp's stalk or tissue of origin is not entirely removed, necessitating thorough reassessment and potentially more aggressive surgical intervention. - Urgent veterinary care is critical for cats exhibiting severe respiratory distress (open-mouth breathing, cyanosis), collapse, inability to stand, or signs of severe pain and bleeding. --- Ear polyps in cats are usually benign inflammatory growths that arise from tissue associated with the middle ear, auditory tube, or nearby pharyngeal lining. They may extend outward into the ear canal or inward toward the nasopharynx behind the soft palate. Their location explains why one cat may have repeated ear infections while another develops noisy breathing, swallowing difficulty, a head tilt, or balance problems. ## At a Glance | Question | Key point | |---|---| | Are feline inflammatory polyps cancer? | They are generally benign, but other masses can look similar | | Which cats are affected? | Often young cats, although any age can be affected | | Can a polyp cause both ear and breathing signs? | Yes, it may extend from the middle ear toward either area | | How is it diagnosed? | Examination under sedation or anesthesia, otoscopy, oral examination, and imaging as needed | | What is the usual treatment? | Removal by traction or surgery, selected according to location and recurrence risk | | Can it come back? | Yes, especially if the stalk or tissue of origin remains | A visible mass should not be pulled at home. The ear canal contains delicate structures, and the deeper attachment cannot be assessed without veterinary examination. ## What Is an Inflammatory Polyp? Merck Veterinary Manual describes inflammatory polyps as smooth, pink, fleshy, stalked masses found in the ears, nose, and throat of cats. They may be called aural polyps, nasopharyngeal polyps, or oropharyngeal polyps depending on the direction of extension. The exact cause is not fully established. Congenital, genetic, and infectious mechanisms have been proposed. The growth is inflammatory rather than a typical malignant tumor, but appearance alone cannot reliably exclude neoplasia or another type of mass. Many polyps are thought to originate in the tympanic bulla, the bony chamber of the middle ear. A stalk can pass through the eardrum into the external ear canal or through the auditory tube into the nasopharynx. ## Signs of an Ear or Middle-Ear Polyp Signs depend on how far the mass extends and which structures are affected. Common aural signs include: - Repeated head shaking - Pawing or scratching at one ear - Ear discharge or odor - Recurrent otitis that improves but returns - Pain when the ear or mouth is handled - A visible pink mass in the ear canal - Reduced response to sound Middle or inner ear involvement can produce: - Head tilt - Loss of balance or falling - Circling - Rapid involuntary eye movements - Facial weakness - A constricted pupil, raised third eyelid, drooping upper eyelid, or sunken appearance of the eye on one side The eye changes are features of Horner syndrome, which can occur when sympathetic nerves traveling near the middle ear are affected. ## Signs of Nasopharyngeal Extension A polyp extending toward the throat may cause: - Noisy upper-airway breathing - Snoring or stertor - Sneezing or nasal discharge - Gagging, retching, or repeated swallowing - Difficulty swallowing - Voice change - Reduced appetite - Labored breathing in severe obstruction Merck Veterinary Manual notes that signs are often chronic and progressive. A cat with open-mouth breathing, blue or gray gums, collapse, or marked respiratory effort requires emergency care. ## Other Conditions That Can Look Similar The differential diagnosis depends on age, location, and associated inflammation. Possibilities include: - Chronic bacterial or yeast otitis - Ear mites - Foreign material - Ruptured eardrum - Middle or inner ear infection - Nasopharyngeal inflammation - Benign glandular growth - Squamous cell carcinoma or another tumor - Ceruminous gland tumor - Lymphoma - Trauma or granulation tissue Older cats with an ear canal mass deserve particular attention because neoplasia becomes a more important concern. Histopathology is the definitive way to characterize removed tissue. ## Veterinary Examination and Diagnosis ### History and physical examination The veterinarian will ask when signs began, whether one or both ears are affected, which treatments were tried, and whether the cat has respiratory, swallowing, balance, or eye changes. The examination includes the external ear, neurologic status, eyes, facial symmetry, oral cavity, and breathing pattern. ### Otoscopy and oral examination Deep inspection is often painful or impossible in an awake cat. Sedation or general anesthesia may be required for a complete otoscopic examination, careful cleaning, assessment of the eardrum, and inspection behind the soft palate. A nasopharyngeal polyp may be felt or seen when the soft palate is retracted under anesthesia. An ear canal polyp may obscure the tympanic membrane. ### Imaging Skull radiographs can show some changes but may miss subtle disease. Computed tomography gives more detailed information about the tympanic bullae, ear canals, nasopharynx, bone change, and mass extent. Magnetic resonance imaging may be selected when soft tissue or neurologic involvement requires further characterization. Imaging is particularly useful when: - Neurologic signs are present - Both sides may be affected - The polyp has recurred - The attachment cannot be identified - A tumor is a concern - Bulla surgery is being planned ### Cytology, culture, and histopathology Ear discharge may be examined for bacteria, yeast, and inflammatory cells. Culture can be useful in recurrent, deep, or treatment-resistant infection. A sample of the mass or the entire removed polyp should be submitted for histopathology because a visual diagnosis is not definitive. ## Treatment Options ### Traction avulsion With the cat under anesthesia, the veterinarian may grasp the polyp and apply controlled traction and rotation to remove it. This can work well when the mass and stalk are accessible. The limitation is that tissue at the site of origin may remain inside the middle ear. Recurrence is therefore possible. Anti-inflammatory medication may be used after removal in selected cases, but medication alone does not reliably remove a mature obstructive mass. ### Ventral bulla osteotomy Ventral bulla osteotomy is a surgical approach to the middle ear. It allows removal of inflammatory tissue and the polyp's origin from the tympanic bulla. It may be recommended for recurrent disease, extensive middle-ear involvement, or cases in which imaging shows material within the bulla. This procedure requires surgical expertise and careful anatomic dissection. Potential complications include Horner syndrome, balance disturbance, facial nerve dysfunction, bleeding, infection, and anesthetic complications. Some postoperative neurologic signs are temporary, but the expected course must be discussed with the surgeon. ### Other approaches The route depends on anatomy. A polyp extending into the ear canal may be approached differently from one behind the soft palate. Severe ear canal disease, destructive tumors, or unusual masses may require more extensive surgery than an uncomplicated inflammatory polyp. ## What to Expect After Removal Recovery instructions may include: - Keeping the cat indoors and restricting activity - Giving prescribed pain relief and anti-inflammatory medicine - Administering antimicrobials only when indicated - Preventing scratching with an Elizabethan collar - Monitoring appetite, breathing, balance, and the surgical site - Returning for rechecks and histopathology results Contact the clinic promptly for worsening head tilt, repeated vomiting, inability to stand, facial weakness, breathing difficulty, bleeding, severe pain, or refusal to eat. Horner syndrome can appear before treatment because of the polyp or after manipulation of the middle ear. The veterinarian should explain whether it is expected to improve and how it will be monitored. ## Recurrence and Prognosis The outlook is generally favorable when an inflammatory polyp is completely addressed and secondary infection or inflammation is managed. Recurrence risk is higher when only the visible portion is removed and the deeper stalk remains. A recurrent mass should not simply be pulled repeatedly without reassessment. Imaging and bulla surgery may be appropriate, and histopathology should be reviewed to confirm that the lesion is inflammatory. Persistent signs after removal can result from: - Residual or recurrent polyp - Chronic otitis media - Irreversible nerve injury - An additional mass - Infection - Disease on the opposite side ## When to Seek Urgent Care Seek urgent veterinary care if a cat has: - Open-mouth breathing or severe respiratory effort - Blue or gray gums - Collapse - Inability to stand - Repeated falling with distress - Sudden facial paralysis - Severe pain - Heavy bleeding from the ear Routine ear cleaner is not an appropriate response to these signs. Avoid placing drops in an ear when the eardrum's status is unknown unless a veterinarian has prescribed that product for the cat. ## Related Articles - [Cat Ear Infection: Causes, Diagnosis, and Treatment](/knowledge/veterinary-medicine/clinical-methods/cat-ear-infection) - [Cat Shaking Head and Scratching Ear](/knowledge/veterinary-medicine/behavior/cat-shaking-head-and-scratching-ear) - [Cat Ear Ringworm](/knowledge/veterinary-medicine/otology/cat-ear-ringworm) ## Related Clinical & Scientific Guides * [What Does It Mean When Your Dog Scratches Their Ears](/knowledge/veterinary-medicine/clinical-methods/what-does-it-mean-when-your-dog-scratches-their-ears) * [Why Was My Cat Choking](/knowledge/veterinary-medicine/clinical-methods/why-was-my-cat-choking) * [Vet Approved Dog Ear Cleaner](/knowledge/veterinary-medicine/clinical-methods/vet-approved-dog-ear-cleaner) ## References 1.
