Comparison of pre- and post-treatment audiometry of long-term sudden sensorineural hearing loss patients (n=21). All values are in mean ± standard deviation.
| Tested frequency | Pre-treatment hearing threshold | Post-treatment hearing threshold | p value |
|---|---|---|---|
| 250 Hz (dB) | 50 ± 20 | 46 ± 17 | 0.08 |
| 500 Hz (dB) | 55 ± 20 | 49 ± 19 | 0.01 |
| 1000 Hz (dB) | 57 ± 21 | 52 ± 19 | 0.03 |
| 2000 Hz (dB) | 60 ± 17 | 59 ± 16 | 0.46 |
| 4000 Hz (dB) | 70 ± 17 | 68 ± 16 | 0.34 |
| 8000 Hz (dB) | 76 ± 13 | 72 ± 17 | 0.17 |
| Low-frequency PTA (dB) | 57 ± 17 | 53 ± 15 | 0.01 |
| Speech-frequency PTA (dB) | 60 ± 15 | 57 ± 13 | 0.02 |
| High-frequency PTA (dB) | 73 ± 14 | 70 ± 15 | 0.18 |
| WRS (%) | 45 ± 28 | 70 ± 28 | <0.01 |
| SRT (dB) | 57 ± 18 | 50 ± 16 | 0.01 |
PTA: pure tone average; WRS: word recognition score; SRT: speech recognition threshold.
Low-frequency PTA: averages 500, 1000, and 2000. Speech-frequency PTA: averages 500, 1000, 2000, and 4000. High-frequency PTA: averages 4000 and 8000. WRS and SRT were not available for analysis in 2 and 1 patients, respectively.
