摘要

Purpose

Acute acoustic trauma (AAT) is a sudden sensorineural hearing loss (SNHL) due to exposure to high intensity impulse noise. There are no acceptable treatment guidelines, although several studies showed steroids could be effective in restoring hearing levels. A recent report suggested that steroids combined with hyperbaric oxygen therapy (HBOT) are a superior regiment for AAT. The purpose of the current study is to investigate the effectiveness of steroids and HBOT for AAT treatment.

Methods

the medical records 90 patients (118 ears) afflicted with AAT and treated with steroids and HBOT were retrospectively reviewed. Inclusion criteria were sensorineural hearing loss of at least 30 dB at the high frequency range (> 3,000 Hz) following exposure to intense sound. Patients who started treatment within 7 days were classified as “Early treatment” group whereas patients who started treatment ≥ 8 days after AAT were classified as “Late treatment”.

Results

The high frequency (3–8 kHz) Pure Tone Average (hPTA) of the entire study population (n = 118) was 40.26 ± 15.42 dB pretreatment vs. 24.99 ± 15.83 dB post treatment (Wilcoxon matched-pairs test, P < 0.0001). Pre-treatment hPTA was not statistically different between early and late study groups, 39.87 ± 16.00 vs. 40.86 ± 14.35 dB in the early vs. late group, respectively (ANOVA, F[3,232] = 22.574, P > 0.05). The post-treatment hPTA on the other hand, was significantly lower in the early vs. late treatment groups (21.93 ± 15.38 vs.31.19 ± 15.09 dB, respectively; ANOVA, F[3,232] = 22.574, P < 0.05).

Conclusion

Combination treatment with corticosteroids and HBOT is highly beneficial in improving hearing outcomes following AAT, when initiated within 7 days. This study was retrospectively registered on July 19th 2020 and assigned the identifier number NCT04482998.
