Table 1.

The mean, SD (column 2) and significance (column 3) of the dB difference of the cochlear potential magnitude between the intact (pre-SCD) condition and after the introduction of the dehiscence (post-SCD) (n = 11)

Frequency (Hz) Mean post/pre ± SD (dB) Significance Mean patch/pre ± SD (dB) Significance
125 −10.1 ± 5.9 P < 0.001 −2.0 ± 4.3 NS
250 −7.1 ± 3.4 P < 0.001 −2.1 ± 2.0 P < 0.01
500 −8.3 ± 4.3 P < 0.001 −2.4 ± 3.6 P < 0.05
1000 −6.5 ± 4.8 P < 0.01 −1.0 ± 2.0 NS
2000 −4.9 ± 3.4 P < 0.001 −1.9 ± 3.5 NS
4000 −2.9 ± 5.2 NS −1.2 ± 3.9 NS
8000 −1.0 ± 10.2 NS 1.3 ± 6.3 NS

NS denotes cases where the null hypothesis that the manipulations do not alter the CP is accepted at the 5% significance level. Column 4 shows the mean dB difference in magnitude between the pre-SCD state and the patched state. Column 5 shows the significance of that difference.
