To evaluate the efficacy of low-dose intratympanic dexamethasone therapy in patients with idiopathic sudden sensorineural hearing loss whose hearing in the affected ear had failed to improve following a course of oral steroid therapy.
A prospective pilot study was undertaken of eight patients with idiopathic sudden sensorineural hearing loss whose hearing had failed to improve after a course of prednisolone. These patients subsequently received 8 mg intratympanic dexamethasone therapy, delivered via a ventilation tube on a weekly basis for 1 month. Clinical outcome was assessed weekly with pure tone audiography.
At the end of the 1-month treatment period, no significant hearing improvement was observed on pure tone audiography in any of the patients (i.e. improvements were all less than 10 dB).
The response to 8 mg of intratympanic dexamethasone used as a salvage therapy for idiopathic sudden sensorineural hearing loss was inadequate. A higher dosage of intratympanic dexamethasone might be required to achieve better outcomes.
