Background: To analyze the clinical efficacy of intratympanic steroid perfusion (ISP) and postauricular steroid injection (PSI) for refractory severe and profound sudden sensorineural hearing loss (SSNHL).
Methods: SSNHL patients who failed a conventional treatment with severe to profound hearing loss [pure tone average (PTA, 0.25-8 kHz) > 60 dB] were treated with ISP or PSI plus antioxidant and neurotrophin for 10 consecutive days.
