What is the management for a patient with an ear perforation related to trauma?

Management of Traumatic Tympanic Membrane Perforation

Initial Assessment and Diagnosis

For traumatic ear perforations, the primary management strategy is conservative observation with ear protection, as most perforations heal spontaneously within 4-8 weeks without intervention. 1, 2, 3

• Confirm the diagnosis through careful otoscopic examination, documenting the size and location of the perforation 1, 2
• Avoid irrigation and pneumatic otoscopy completely, as these can cause middle ear infection, vertigo, or ototoxicity when perforation is present 1, 2
• Carefully suction blood, purulent secretions, and debris from the canal using gentle technique 2
• Assess for red flag symptoms including vertigo, nausea, vomiting, or facial paralysis, which require immediate ENT referral 2, 4

Hearing Assessment and Ossicular Chain Evaluation

• Obtain an audiogram to assess hearing loss severity 2
• Conductive hearing loss >30 dB suggests ossicular chain disruption and warrants ENT consultation 2
• Profound sensorineural hearing loss may indicate inner ear nerve damage requiring urgent specialist evaluation 2
• Consider mastoid radiographs or CT scans in cases of significant trauma 2

Ear Protection Measures (Critical)

Keep the ear completely dry to prevent infection - this is the cornerstone of conservative management 1, 2, 4

• Use earplugs or cotton balls coated with petroleum jelly when showering 1
• Avoid swimming entirely until the perforation has healed 1
• Instruct patients to avoid inserting cotton-tipped applicators, which can cause further trauma or leave behind fibers 1

Antibiotic Therapy: When and What to Use

For Clean Traumatic Perforations (No Infection)

• Systemic antibiotics are NOT indicated for uncomplicated traumatic perforations without signs of infection 1, 2
• Observation alone is appropriate for most cases 2, 3

For Perforations with Signs of Infection or Drainage

Use topical fluoroquinolone antibiotics as first-line therapy - they are the ONLY safe topical antibiotics for perforated eardrums 1

• Ciprofloxacin-dexamethasone or ofloxacin drops are the preferred agents due to lack of ototoxicity even with direct middle ear exposure 1
• Clean the ear canal first by suctioning debris before applying drops to enhance drug delivery 1
• Proper instillation technique: warm bottle in hand 1-2 minutes, patient lies with affected ear up, instill drops, pump tragus 4 times, maintain position for 5 minutes 1
• Limit treatment to maximum 10 days to prevent otomycosis from prolonged quinolone use 1

Critical Medications to AVOID

Never use aminoglycoside-containing drops (neomycin, gentamicin, polymyxin B-neomycin combinations) - these cause severe permanent sensorineural hearing loss after exposure through perforations 1, 5

• The FDA explicitly warns that neomycin can induce permanent cochlear damage and should never be used with perforated tympanic membranes 5
• Avoid alcohol-containing drops - alcohol in the middle ear is both painful and potentially ototoxic 1
• Do not use cerumenolytics or mineral oil when the tympanic membrane is not intact 1

When to Add Systemic Antibiotics

Add oral antibiotics only when: 1

• Cellulitis of the pinna or adjacent skin is present
• Signs of severe infection exist
• Patient has diabetes or is immunocompromised
• Topical therapy fails after 48-72 hours despite adequate drug delivery

For perforations related to acute otitis media specifically, oral antibiotics may be prescribed 2

Follow-Up and Reassessment

• Reassess within 48-72 hours if no response to initial therapy to confirm diagnosis and exclude other causes 1
• Most traumatic perforations heal spontaneously within 4-8 weeks 2, 3
• All pediatric cases in one study healed spontaneously without intervention 3
• Only 4-8% of patients require oral antibiotic rescue therapy 1

When to Refer to ENT

Immediate ENT referral is indicated for: 2, 4

• Traumatic perforations associated with vertigo or significant hearing loss (>30 dB conductive loss)
• Continuous pain, facial paralysis, or other alarming signs
• Perforations that do not heal within 1 month
• Suspected ossicular chain disruption
• Chronic perforations from chronic otitis media or cholesteatoma

Surgical Considerations

• Perforations that fail to heal spontaneously after 1-2 months may be considered for surgical repair (tympanoplasty) 2, 6
• Cartilage tympanoplasty shows better structural outcomes (fewer recurrent perforations) compared to temporalis fascia, though hearing outcomes are similar 7
• Novel adjuvant therapies using fibroblast growth factor with gelatin scaffolds show significantly higher closure rates (98% vs 10%) in chronic perforations 7

Common Pitfalls to Avoid

• Never irrigate the ear when perforation is present or suspected 1, 2
• Never use neomycin-containing preparations - even if you cannot visualize the tympanic membrane due to canal edema, assume perforation may be present 1, 5
• Do not delay ENT referral for red flag symptoms (vertigo, severe hearing loss, facial paralysis) 2, 4
• If patient tastes ear drops, this indicates perforation and they should inform their doctor immediately 1
