Concurrent hyperbaric oxygen therapy (HBOT) and intratympanic steroid application (ITS) are beneficial as salvage therapy for therapy-refractory sudden sensorineural hearing loss (SSNHL). The findings encourage further research on the treatment of noise-induced and idiopathic SSNHL with concurrent use of HBOT and ITS respecting also patients with long-term or therapy-refractory SSNHL.
