Otitis Media (Middle Ear Infection) in Dogs and Cats – Vet Diagnosis and Treatment for 2025 🧠🦻🐾
Otitis media refers to an infection or inflammation of the middle ear. Unlike otitis externa, which affects the external ear canal, otitis media occurs deeper inside the ear and can cause serious complications. In this 2025 veterinary guide, Dr Duncan Houston explores the causes, signs, diagnosis, and treatment options available for both dogs and cats. 🐶🐱
🔍 What Is Otitis Media?
Otitis media affects the area behind the eardrum and can damage nearby nerves. This leads to neurological symptoms like:
- 🌀 Head tilt
- 🤕 Lack of balance (ataxia)
- 👁️ Nystagmus (involuntary eye movement)
- 🗣️ Facial paralysis or drooping on one side
🦠 How Does It Develop?
Most commonly, otitis media results from untreated or chronic otitis externa. When the external infection breaches the eardrum, it spreads to the middle ear. 🧫
Other causes include:
- 👃 Nose or throat infections
- 🔎 Foreign objects in the ear canal
- 🍄 Fungal infections
- 🎈 Inflammatory polyps (especially in cats)
- 🧬 Cancer
- 🐾 Congenital abnormalities
🐾 Who Is at Risk?
No breed or sex is immune, but certain dogs like beagles, basset hounds, and Cavalier King Charles Spaniels are more susceptible. Cavaliers, in particular, can develop a condition called primary secretory otitis media (PSOM)—a middle ear disorder that doesn’t start with external ear infections. 📋
🩺 How Is Otitis Media Diagnosed?
1. Physical Exam
Your vet will look for signs such as:
- 🧠 Head tilt, balance loss
- 👃 Ear odor or discharge
- 🤒 Pain when opening the mouth
- 👁️ Horner’s syndrome (eye changes)
2. Otoscopy
Visual inspection of the eardrum using an otoscope. Sedation may be required for comfort and thoroughness. 🧐
3. Cytology and Culture
- 🧫 Samples of ear material are cultured to identify bacteria or fungi
- 💊 Guides appropriate antimicrobial treatment
4. Radiographs and Imaging
If otitis media is suspected, advanced imaging may be needed:
- 🦴 X-rays to assess bony changes in the ear
- 🖥️ CT scans for bone damage
- 🧠 MRI for soft tissue abnormalities
💊 Treatment Strategies
1. Deep Ear Cleaning
🧼 Debris in the ear blocks medications. Vets may perform ear flushes under anesthesia to clear both the external and middle ear canals. 💧
2. Topical Medication
May include antibiotics, antifungals, or corticosteroids. In some cases, medications are infused into the middle ear under sedation. 🩹
3. Systemic Therapy
Oral medications are often needed to reach deeper tissues:
- 💊 Antibiotics
- 💊 Antifungals
- 💊 Anti-inflammatory drugs
4. Surgery (If Needed)
If the infection is advanced or medical therapy fails, your vet may recommend a total ear canal ablation (TECA). This major surgery removes the infected canal and bones to stop pain and progression. 🛠️
📅 Follow-Up and Monitoring
Regular rechecks every 10–14 days are vital. Your vet will monitor:
- 🎯 Tympanic membrane healing (usually 3–5 weeks)
- 🧫 Repeat cytology for infection control
- 📋 Adjustment of medications as needed
📈 Prognosis
Most pets recover well if treatment starts early. However, long-standing infections, antibiotic resistance, or severe nerve damage may lower the success rate. Some neurologic issues (e.g., facial paralysis) can be permanent. ⚠️
🧠 Quick Comparison: Otitis Externa vs Media
| Feature | Otitis Externa | Otitis Media |
|---|---|---|
| Affected Area | External ear canal | Middle ear behind eardrum |
| Common Symptoms | Redness, wax, odor | Head tilt, nystagmus, pain opening mouth |
| Treatment | Topical meds, cleaning | Systemic meds, possibly surgery |
| Prognosis | Good with treatment | Good if caught early |
🛡️ Prevention Tips
- 🧼 Clean your pet’s ears regularly using vet-approved solutions
- 📆 Schedule routine checkups for early detection
- 🌊 Dry ears after swimming or bathing
- 🔬 Treat external infections quickly to prevent deeper progression
- 🧬 Monitor high-risk breeds for early neurological signs
