Cat Ear Hematoma: A Vet’s 2025 Guide to Causes, Treatment & Recovery 🐱🦻
By Dr Duncan Houston, BVSc
🔍 What Is a Cat Ear Hematoma?
An ear hematoma, also known as an aural hematoma, is a blood-filled pocket that forms between the skin and cartilage of the ear flap. It usually feels soft, spongy, warm, and often painful. It most commonly affects one ear :contentReference[oaicite:3]{index=3}.
⚠️ Why Does It Happen?
The primary cause is trauma to small blood vessels in the ear flap. This trauma usually results from violent head shaking or scratching—often due to underlying ear disease such as:
- Otitis externa (bacterial or yeast infection)
- Ear mites
- Allergies
- Foreign bodies, polyps
- Fight wounds or bites
- Rare coagulopathies
Persistent scratching triggers bleeding into the ear tissue :contentReference[oaicite:4]{index=4}.
🚩 Signs to Watch For
- Soft, warm swelling on the inner ear flap
- Head shaking, pawing at ear, head tilt
- Ear pain and tenderness
- Possible ear discharge or odor from underlying infection :contentReference[oaicite:5]{index=5}
🩺 Diagnosing an Ear Hematoma
- Physical exam—visual and palpation reveals soft swelling
- Sampling aspirated fluid confirms blood content :contentReference[oaicite:6]{index=6}
- Ear cytology/swabs for infection or mites
- Investigate underlying cause—otoscopy for foreign bodies/polyps, ear exam, bloodwork for clotting issues :contentReference[oaicite:7]{index=7}
🛠️ Treatment Options
A. Drainage Alone
Needle aspiration may relieve pressure short-term, but recurrence is common within days unless underlying cause is managed :contentReference[oaicite:8]{index=8}.
B. Needle + Steroid Injection
Draining the blood and injecting steroids into the pocket reduces inflammation. This less invasive method may work for small, early hematomas :contentReference[oaicite:9]{index=9}.
C. Surgical Repair (Recommended)
Most effective treatment, especially for large or recurrent hematomas:
- Anesthesia and aseptic prep
- Incisions made to drain the hematoma
- Placement of sutures or tubes to eliminate blood space and prevent reaccumulation
- Stabilize ear with bandages or suture-through technique :contentReference[oaicite:10]{index=10}
- Concurrent treatment for ear infection, mites, allergies :contentReference[oaicite:11]{index=11}
D. Conservative “Benign Neglect”
Allowing small hematomas to resolve on their own may lead to scarring, deformity (“cauliflower ear”), discomfort, and persistent infection :contentReference[oaicite:12]{index=12}. ↪ Not commonly advised.
💊 Medications & Adjunctive Care
- Systemic antibiotics for underlying infection
- Anti-inflammatories (NSAIDs like meloxicam or steroids)—short-term to reduce swelling :contentReference[oaicite:13]{index=13}
- Intralesional steroids such as triamcinolone in certain cases :contentReference[oaicite:14]{index=14}
- Pain relief as needed
- Cold laser therapy in some clinics to aid healing
📅 Recovery & Follow-Up Care
- Monitor sutures or drain sites for 7–14 days
- Use an E‑collar to prevent scratching
- Follow-up rechecks for ear health, catheter/drain removal
- Watch for recurrence; repeat drainage or surgery if needed :contentReference[oaicite:15]{index=15}
- Address and manage underlying ear diseases long-term
⚖️ Prognosis & Outcomes
- Surgery typically yields excellent healing with minimal deformity :contentReference[oaicite:16]{index=16}
- Needle/steroid approach can work for very small or early hematomas :contentReference[oaicite:17]{index=17}
- Untreated: may heal slowly but often leaves permanent deformity and predisposition to recurrence
- Underlying disease control is crucial to prevent repeats
🏡 Home Care Tips for Comfort
- Keep E‑collar on throughout recovery
- Clean drain sites per vet instructions
- Limit vigorous activity to prevent trauma
- Use gentle ear cleansers to keep ear canals healthy
- Maintain treatment for infections or mites
- Use Ask A Vet app for guidance
- Calm the environment with comforting Woopf & Purrz products
🛡️ Prevention Strategies
- Regular ear exams and cleaning
- Prompt treatment for ear infections, parasites, allergies
- Monitor cats prone to ear trauma or fights
- Keep indoor safe and stress low
- Routine vet visits for ear health
