Abstract

To evaluate the effect of combined hyperbaric oxygen therapy (HBOT) and steroid therapy in severe idiopathic sudden sensorineural hearing loss (ISSNHL). Between January 2010 and July 2017, we evaluated 218 patients with ISSNHL and divided them into 2 groups: those with hearing loss greater than 80 dB and those with hearing loss of 60-79 dB. Each group was further divided into 3 groups according to the treatment method: oral steroids alone (PO), PO+intratympanic injection (IT), and PO+IT+HBOT. The treatment effect was evaluated for improvement in hearing thresholds at mid-term (3 weeks later) and final term (2 months later). When comparing the 3 treatment groups within the group that had a hearing loss greater than 80 dB, no differences were observed in the gaps in hearing thresholds and in the duration of improvement (P = .0764 and .2938, respectively). However, in the group with 60-79 dB hearing loss, the gaps in hearing thresholds at mid-term were 27.50 dB in the PO group, 38.13 dB in the PO+IT group, and 51.25 dB in the PO+IT+HBOT group. The treatment was more effective and faster in the initial period in the PO+IT+HBOT group than in the other groups. In addition, the results of frequency analysis showed greatest treatment e...Continue Reading
