Auricular hematoma
From WikEM
(Redirected from Auricular Hematoma)
Contents
Background
- Caused by blunt trauma to external ear
- Associated with contact sports such as boxing, wrestling, etc.
- Separation of perichondrium from underlying cartilage tears the adjoining blood vessels[1]
- Usually occurs on anterior surface, since skin is firmly adherent to cartilage (on posterior ear, there is underlying muscle and adipose is it loosely adherent to cartilage)[2]
- Recurrent hematomas lead to infection and/or cartilage necrosis and neocartilage formation (i.e. "cauliflower ear")
- Goal of treatment is to prevent "cauliflower ear" deformity by draining the hematoma in a timely fashion
Clinical Features
- Gross deformity/swelling to pinna after recent blunt trauma
- Loss of typical auricular landmarks/anatomy[3]
- Pain out of proportion[3]
- Hematoma most commonly collects in the scaphoid fossa and the concha

Subacute/Delayed
Evaluation

Management
Indications for drainage[4]
- Traumatic swelling that deforms pinna
- Within 7 days of trauma
Contraindications
In these cases, refer to ENT due to formation of granulation tissue that may require debridement
- Recurrent or chronic hematomas
- > 7 days from trauma
Procedure
- Perform an auricular block
- Evacuate the clot
- Option 1: Make semi-circle incision inside the inner curvature of the helix or antihelix
- Make incisions along natural auricular crease for cosmesis
- Remove hematoma by milking of the hematoma toward the incision. Suction or curettage may also be helpful
- Use a butterfly hemostat or suture kit needle driver to break up any hematoma that is not easily coming out
- Option 2: Use large-bore needle/syringe to aspirate hematoma[2]
- Needle aspiration generally is not sufficient treatment[3], especially for larger hematomas as clot has usually already formed and cannot be aspirated
- Option 1: Make semi-circle incision inside the inner curvature of the helix or antihelix
- Prevent re-accumulation of hematoma (goal is to close the dead space between perichondrium and cartilage[1]). Multiple methods available:
- Option 1: Compression dressing
- Pack the helix with petroleum jelly-impregnated gauze
- Place regular gauze both in front of and behind the ear
- Circle the head with a compressive wrap
- Generally only moderately successful, and subject to poor compliance (especially with athletes[1])
- Option 2: Suture
- Use fast-absorbing sutures
- Place running or interrupted sutures through cartilage and both anterior and posterior skin of auricle in mattress fashion[2]
- This should reappose the perichondrium
- Consider leaving incision open (with wound edges approximated by mattress sutures) to allow for continued drainage[1]
- Option 3: Bolster sutured in place- combination of the above two methods
- Use non-absorbable 2-0 or 3-0 nylon
- Pack the helix with petroleum jelly impregnated gauze. Place a thick layer of gauze behind the ear
- Perform a running quilt stitch through the anterior gauze, through the pinna, and through the posterior gauze
- Option 1: Compression dressing
- Antibiotics
- Often used by our ENT colleagues in all patients though it is actually only recommended for immunocompromised patients
- Cover pseudomonas and S. aureus- Cipro is the most commonly used
Disposition
- Discharge
- ENT followup in 2-3 days for suture removal or dressing removal and wound check
