Auricular (Ear) Hematoma - Treatment

Note: The term "ear lobe hematoma" is clinically uncommon - the ear lobe has no cartilage, so blunt trauma there rarely causes a true hematoma requiring drainage. The condition you are most likely asking about is an auricular hematoma - blood collection between the perichondrium and the underlying cartilage of the pinna/auricle. This is the condition described below. True ear lobe hematomas (no cartilage involved) are usually managed conservatively with compression alone.

Pathophysiology

Goals of Treatment

1. Drain the hematoma completely
2. Eliminate the dead space to prevent reaccumulation
3. Prevent avascular necrosis of cartilage
4. Prevent cauliflower ear deformity

Step-by-Step Management

1. Anesthesia

• Regional auricular nerve block is preferred - it provides near-total analgesia and avoids distorting the hematoma with local infiltration
• Alternatively, local infiltration with lidocaine around the hematoma margin

2. Drainage - Two Options

• Use sterile technique
• Make a semicircular incision through the skin along the inner curvature of the helix or antihelix - the minimal incision necessary to drain the hematoma, placed to minimize cosmetic deformity
• Do not incise the underlying perichondrium
• Remove the hematoma by gentle suction or curettage
• Close the incision with sutures after evacuation
• Tintinalli's Emergency Medicine, block 20

• Simpler but associated with higher recurrence rates
• Aspiration alone does not completely evacuate clot, leading to deformity and increased morbidity
• Generally insufficient as the sole treatment

3. Compression - Critical Step

• Place a dental roll or firm sterile pledget coated with antibiotic ointment over the sutured site
• Secure with through-and-through (mattress) sutures connecting to a matching bolster on the posterior surface of the ear
• Leave the bolster in place for 4-7 days
• Recheck at 24 hours to confirm no reaccumulation

• Pack the helix with petroleum jelly-impregnated gauze
• Place regular gauze in front of and behind the ear
• Wrap the head circumferentially with a compressive bandage
• Tintinalli's Emergency Medicine, block 20

Antibiotics

• Routine prophylaxis is generally not required in immunocompetent patients
• Antistaphylococcal antibiotics (e.g., dicloxacillin, cephalexin) are commonly given - cover S. aureus and P. aeruginosa, the two organisms most likely to cause post-traumatic chondritis
• Reserve for immunocompromised patients per Tintinalli's, but Family Medicine text recommends prophylactic antistaphylococcal coverage routinely
• Tintinalli's Emergency Medicine, block 20; Textbook of Family Medicine 9e, block 5

Follow-Up and Return to Activity

• Recheck at 24 hours to assess for reaccumulation
• Patients may return to wrestling or boxing with appropriate headgear after the bolster is removed
• Textbook of Family Medicine 9e, block 5

Long-Standing Hematoma / Cauliflower Ear

• If the hematoma is chronic or cauliflower ear has already formed, simple drainage is insufficient
• Requires debridement of fibrosis and cartilage - refer to ENT/plastic surgery
• Improvement of established cauliflower ear deformity is difficult; specialist plastic surgery consultation should be sought
