• Treatment of idiopathic sudden hearing loss (SHL) is still a great problem for the physicians, due to the still unexplained etiopathogenesis of the disease. This retrospective study includes 115 patients with idiopathic SHL and compares two therapy regimens. Of the total number of patients, 51 had been primarily treated by hyperbaric oxygen (HBO) at 2.8 bar. The remaining 64 patients had been treated by pentoxifylline infusions in increasing and decreasing doses. Hearing thresholds were ascertained at the frequencies of 250, 500, 1,000, 2,000 and 4,000 Hz using pure-tone audiometry. The results after treatment showed a statistically significant improvement of hearing by 46.35 (SD ±18.58) dB hearing level (HL) in the group of patients treated with HBO, compared with an improvement of hearing by 21.48 dB HL (SD ±13.5) in the group of patients treated with pentoxifylline infusions (p < 0.001). Furthermore, hearing recovered to physiological values in 24 of 51 (47.1%) HBO-treated patients, compared to only 4 of 64 (6.2%) of the pentoxifylline-treated patients. Furthermore, after pentoxifylline treatment only 8/64 (12.5%) patients showed partial recovery, whereas after HBO therapy 21/51 (41.2%) patients improved up to a mild persistent hearing loss. This indicates strong evidence that HBO therapy is more effective in the treatment of idiopathic SHL than conventional rheological treatment. However, more prospective clinical trials should confirm the efficiency of HBO therapy and lead to its wider application.
