Abstract:
OBJECTIVE:To investigate the efficacy of round window catheter placement with dexamethasone perfusion for 13 patients with intractable sudden sensorineural hearing loss (SSNHL).
METHOD:Dexamethasone (2.5 mg) was perfused transtympanically through round window catheter by Micro-infusion pump. The perfusion was taken twice a day and continued for an hour each time, for a total of 7 days.
RESULT:Thirteen patients have been followed up for 1 month. Five of them (38.5%) were demonstrated a 17-54 dB improvement in pure-tone threshold average (PTA). The other 8 patients (61.5%) had no effect.
CONCLUSION:Round window catheter placement with dexamethasone perfusion is a cost-effective and useful treatment for SSNHL patients who had no effect through conventional therapy, although hearing thresholds of these patients had hardly improved to normal levels.
