Sun H, et al. - Experts compared the effectiveness of intratympanic dexamethasone (ITD) therapy vs hyperbaric oxygen(HBO) therapy for the salvage treatment in patients with high-frequency sudden sensorineural hearing loss (SSNHL) after failing conventional therapy.

As per data, compared to HBO therapy, better improvements of tinnitus and hearing gains at 8 KHz were noted with ITD therapy in patients with refractory high-frequency SSNHL
