mg/ml), methylprednisolone (40 mg/ml) and triamcinolone acetonide (40 mg/ml). Treatments

included initial therapy (alone, or combined with systemic corticosteroids) and salvage.

Except for the posterosuperior angle, other locations on the tympanic membrane can be used

for injection. The commonly applied injection frequency was once a day, and once every 2-4

days; 77.1% had injection duration within 2 weeks. Initial intratympanic injection, alone or

combined with systemic corticosteroids and salvage, all resulted in hearing improvement

with similar rates. The most common discomforts were otalgia and

dizziness/lightheadedness. Conclusion: Intratympanic corticoid injection is an effective

treatment method, and is well applied in both initial and salvage regimens.
