Treatment of Traumatic Ear Injury After Assault
Incision and drainage is the most appropriate treatment for this 19-year-old man with traumatic ear injury following assault, as the clinical presentation is most consistent with auricular hematoma or perichondrial abscess requiring urgent surgical intervention to prevent cartilage necrosis and permanent deformity. 1
Understanding the Clinical Context
Without seeing the supplemental image, the key diagnostic considerations after blunt ear trauma from assault include:
- Auricular hematoma (blood collection between perichondrium and cartilage) presenting as fluctuant swelling over the cartilaginous ear 1
- Auricular perichondritis/abscess presenting as painful swelling, warmth, and redness affecting the cartilaginous portion while often sparing the earlobe 1, 2
- Simple contusion or laceration requiring only conservative management 3, 4
The fact that this is a multiple-choice question with "incision and drainage" as an option strongly suggests a collection requiring evacuation rather than simple inflammation.
Why Incision and Drainage is the Correct Answer
If an abscess or significant hematoma is present, surgical incision and drainage are often necessary. 1 This is critical because:
- Untreated auricular hematomas lead to cartilage necrosis from separation of perichondrium from its blood supply 5
- Once an abscess develops, good cosmetic preservation of the auricular cartilage is difficult to maintain without prompt drainage 1
- Delayed treatment results in "cauliflower ear" deformity that is permanent 3, 5
Why the Other Options Are Incorrect
Intravenous Antibiotic Prophylaxis (Option A)
- Systemic antibiotics should NOT be prescribed for uncomplicated acute otitis externa or simple auricular trauma 6
- IV antibiotics are reserved for severe perichondritis with systemic symptoms or necrotizing otitis externa in immunocompromised patients 1, 2
- A collection (hematoma or abscess) requires drainage first; antibiotics alone will not resolve it 1, 5
Ice Packs (Option B)
- While ice packs play a role as adjunctive non-pharmacological measures for pain control in trauma 1, they are insufficient as definitive treatment for auricular hematoma or abscess
- Ice may provide symptomatic relief but does not address the underlying pathology requiring evacuation 1
- Delayed definitive treatment leads to irreversible cartilage damage 5
Topical Antibiotics (Option D)
- Topical antibiotics are first-line for auricular perichondritis without abscess formation 2
- Fluoroquinolones (ciprofloxacin or levofloxacin) provide excellent coverage against Pseudomonas aeruginosa and Staphylococcus aureus, the most common pathogens 1, 2
- However, if an abscess is present, topical therapy alone is inadequate and surgical drainage is required 1, 2
Post-Drainage Management
After incision and drainage, appropriate adjunctive therapy includes:
- Fluoroquinolone antibiotics (ciprofloxacin or levofloxacin) to cover common pathogens 1, 2
- Pain management with acetaminophen or NSAIDs as first-line agents 6
- Pressure dressing to prevent reaccumulation 5
- Close follow-up within 48-72 hours to assess healing 2, 6
Critical Pitfalls to Avoid
- Do not delay drainage hoping conservative measures will suffice—cartilage necrosis can occur rapidly 5
- Do not rely on antibiotics alone when a collection is present—source control through drainage is essential 1, 5
- Do not underestimate the cosmetic and functional consequences of inadequate initial treatment 1, 3
