Objective:
To investigate the efficacy of intratympanic dexamethasone injection (IDI) for 23 patients with intractable sudden sensorineural hearing loss (SSNHL).
Method:
Dexamethasone (5 g/ml) was injected into the middle ear. The injection was repeated once two days and had a total of 4 doses (10 mg).
Result:
The 23 patients were followed up for one month. Eight of 23 patients (34.8%) demonstrated a 17 to approximately 54 dB improvement in PTA and 15 of 23 (65.2%) had no response.
Conclusion:
