Abstract:
Hyperbaric oxygen after failure of conventional therapy for sudden deafness. Problems/objectives: We inves- tigated the effect of secondary hyperbaric oxygen therapy (HBO) for patients with idiopathic sudden sensorineural hear- ing loss after unsuccessful conventional treatment. Methodology: We retrospectively evaluated 3 groups: 100 patients without further treatment (group 1), 160 patients with secondary HBO at 1.5ATA (group 2), and 56 patients with secondary HBO at 2.5ATA (group 3). Results: In group 1, a mean hearing gain (MHG) of 2.6 ± 15 dB was found at the end of the follow-up period.After HBO, a MHG of 3.1 ± 9 dB in group 2 and 19.7 ± 23 dB in group 3 was achieved. The results in group 3 were statistically significant in comparison to group 1 (p < 0.007) and to group 2 (p < 0.009). With HBO after initial therapy failure, there is a significant correlation of MHG with time delay before HBO (p < 0.03). Conclusions: HBO at 2.5ATA in patients with idiopathic sudden sensorineural hearing loss after unsuccessful conven- tional treatment yields significant improvement of hearing. MHG is higher when time delay before HBO is shorter.
