Rational Use of Steroids for Ear Conditions

Systemic Corticosteroid Therapy

The American Academy of Otolaryngology-Head and Neck Surgery recommends systemic corticosteroids for sudden sensorineural hearing loss (SSNHL), with treatment ideally initiated within the first 14 days of symptom onset, though benefit has been reported up to 6 weeks after onset 1, 2
For SSNHL, prednisone should be administered at 1 mg/kg/day as a single dose (maximum 60 mg daily) for 7-14 days, followed by a taper over a similar time period 3, 2
Methylprednisolone (48 mg/day) or dexamethasone (10 mg/day) are alternative options 3
Early treatment at appropriate starting doses is crucial as underdosing should be avoided to ensure optimal outcomes 2
Common side effects include hyperglycemia, hypertension, insomnia, and weight gain 3
Patients with certain conditions (e.g. diabetes, hypertension, glaucoma) may not be suitable candidates for systemic corticosteroids 3

IT steroids are recommended as initial therapy option for SSNHL (particularly for patients who cannot receive systemic steroids) 1, 3
IT steroids are also recommended as salvage therapy when patients have incomplete recovery from SSNHL 2-6 weeks after onset of symptoms 4
Dexamethasone: 24 mg/mL (compounded) or 10 mg/mL (stock) if compounded concentration unavailable 3
Methylprednisolone: 40 mg/mL or 30 mg/mL 3
Inject 0.4 to 0.8 mL into middle ear space up to 4 injections over a 2-week period 3
Higher concentrations appear to have better outcomes 1

IT steroids achieve higher perilymph steroid concentrations compared to systemic administration 1, 3
IT steroids are a reasonable alternative to systemic therapy for patients who cannot receive systemic corticosteroids 3
One meta-analysis showed significantly better outcomes with dexamethasone compared to methylprednisolone, though study designs varied considerably 5

Treatment with corticosteroids offers greatest recovery when started within the first 2 weeks of symptom onset 2
For salvage therapy with IT steroids, treatment should be initiated within 2-6 weeks after onset of symptoms 4
IT steroids: Pain, transient dizziness, infection, persistent tympanic membrane perforation, and possible vasovagal or syncopal episode during injection 1
Systemic steroids: Acne, blurred vision, cataracts/glaucoma, easy bruising, insomnia, hypertension, increased appetite, weight gain, lower resistance to infection, muscle weakness, osteoporosis, gastric irritation 3
For ear infections with tympanostomy tubes, antibiotic-steroid combination ear drops (e.g., ciprofloxacin-dexamethasone) are preferred over oral antibiotics 6
