Overview

Tinnitus is a clinically and pathophysiologically heterogeneous symptom which incidence shows an increasing trend. Hearing loss has been identified as the most relevant etiological factor in the development of tinnitus. The aim of our study was to verify the nature and extent of the relationship between sudden hearing loss and tinnitus after the application of hyperbaric oxygen therapy (HBOT). We processed data of 99 subjects who were treated with HBOT within the primary (n = 63) and secondary treatment (n = 36). The initial range of hearing impairment was monitored in patients with sudden hearing loss with currently diagnosed tinnitus (HL + T) vs. without tinnitus (HL). There were no statistically significant differences in the initial hearing impairment between these two subgroups HL + T and HL in the sample of patients treated with the primary treatment. In the group of patients with secondary treatment, there was a statistically significant lower hearing loss at the frequencies of 500 Hz and 1,000 Hz (p < 0.05) in HL + T individuals (n = 18) prior to initial therapy compared to the HL group (n = 18), resp. After the use of HBOT primary treatment, there was a statistically significant improvement in hearing (p < 0.01) and intensity of tinnitus was reduced (p = 0.05) in the whole HL + T group. There was no significant improvement in the group of patients who received secondary treatment. There was a moderate correlation between tinnitus and hearing loss after the termination of HBOT only in patients with primary treatment (R = 0.43). We can conclude that HBOT can, to a certain extent, therapeutically influence a variety of factors that modulate tinnitus and hearing loss.

Key words:
tinnitus – sudden hearing loss – hyperbaric oxygen therapy
