Dog ear polyps are benign tissue growths that develop inside the ear canal, often causing chronic ear infections, head shaking, hearing loss, and balance problems — and while surgical removal is usually required for lasting relief, most dogs recover well with proper treatment.
This guide is for informational purposes only. Please consult a veterinarian for diagnosis and treatment of your dog’s ear condition.
What Is a Dog Ear Polyp?
A dog ear polyp (also called a nasopharyngeal polyp in some anatomical contexts, or aural polyp) is a benign, grape-like tissue growth that develops in the ear canal or middle ear. Unlike tumors, polyps are non-cancerous and arise from the normal lining of the ear canal — typically the result of chronic inflammation from repeated infection or irritation.
Ear polyps are more frequently diagnosed in cats than dogs, but they do occur in canine patients — particularly in breeds with narrow ear canals or floppy ears that trap moisture, such as Cocker Spaniels, Poodles, Shar-Peis, and Bulldogs. They can develop at any age but are more common in middle-aged to senior dogs with a history of chronic ear issues.
Symptoms to Watch For
Ear polyps often mimic the symptoms of chronic ear infections, which is why they can be missed or misdiagnosed for months or years. Key signs include:
- Chronic, recurrent ear infections that don’t fully resolve with treatment
- Head shaking or pawing at the affected ear
- Foul-smelling ear discharge (brown, yellow, or bloody)
- Head tilt toward the affected side
- Balance problems or vestibular signs if the middle ear is involved
- Reduced hearing in the affected ear
- Facial nerve paralysis in severe cases (drooping lip, eye)
The hallmark feature that distinguishes polyps from simple ear infections is recurrence despite treatment. If your dog’s ear infections keep coming back — especially in just one ear — a polyp or other structural abnormality should be investigated.
Diagnosis
Veterinary diagnosis of an ear polyp typically begins with a thorough otoscopic examination — looking into the ear canal with a light and magnifier. However, polyps in the middle ear or deeper portions of the canal can be difficult to visualize without sedation and specialized equipment.
Imaging — specifically CT scan or MRI — is often recommended to fully evaluate the extent of the polyp, especially if middle ear involvement is suspected. CT provides the best detail of the ear’s bony structures and helps surgeons plan the approach. Video otoscopy (using a small camera in the ear canal) under anesthesia is another valuable diagnostic and potentially therapeutic tool.
Treatment & Surgery
Medical management alone (ear drops, antibiotics, anti-inflammatories) rarely resolves ear polyps long-term. Surgical removal is the definitive treatment.
The main surgical approaches are:
- Traction avulsion: The polyp is grasped and pulled away via the ear canal. This can be done with video otoscopy or during surgery. Risk of recurrence is higher.
- Total ear canal ablation (TECA): Removal of the entire ear canal, used for severe or recurrent cases. More invasive but curative for canal disease.
- Ventral bulla osteotomy (VBO): Surgical opening into the middle ear through the skull, used when the middle ear (bulla) is involved. Highly effective but technically demanding.
| Procedure | Estimated Cost (US) | Recurrence Risk |
|---|---|---|
| Traction avulsion | $300–$800 | Moderate–High |
| TECA (total ear canal ablation) | $2,000–$5,000 | Low |
| VBO (ventral bulla osteotomy) | $2,500–$6,000 | Very Low |
| Imaging (CT/MRI) | $1,500–$2,500 | N/A |
US cost estimates as of 2026; vary by region and specialist vs. general practice.
Recovery After Surgery
Recovery depends on the procedure performed. After traction avulsion, most dogs return to normal within a week, though inflammation and discharge are common initially. After TECA or VBO, recovery takes 2–6 weeks with restricted activity, pain management, and antibiotic therapy. Some dogs experience temporary facial nerve dysfunction (drooping face) after bulla surgery, which usually resolves within weeks to months.
For dogs with a history of ear infections, regular ear cleaning and veterinary check-ups are important to prevent recurrence. Explore our veterinary clinics directory to find an ear specialist near you.
