Comparison of simultaneous systemic steroid and hyperbaric oxygen treatment versus only steroid in idiopathic sudden sensorineural hearing loss.

A retrospective chart review to assess the effectiveness of hyperbaric oxygen treatment in sudden sensorineural hearing loss. 44 patients aged between 17-67 years diagnosed with idiopathic sensorineural hearing loss less than 30 days were admitted to our clinic Patients were treated with systemic steroid alone or systemic steroid plus hyperbaric oxygen therapy. In the comparison of two groups, there was no statistically significant difference of audiometric evaluation (P>0.0028) found in hearing improvement for each frequency on 5th day of the treatment and post treatment. Age (≤45 and >45) and initial hearing level (≤60 dB. And >60 dB.) does not seem to be an influential factor according to the results of the study (P>0.0007). The present study did not show more superior healing effect of hyperbaric oxygen therapy added to systemic steroid therapy than steroid infusion alone. The results are consistent with those of some papers. However there are also conflicting data that support significant effect of hyperbaric oxygen therapy. Routine administration of this therapy seems to be unnecessary in view of these results.
