Table 3.

The mean absolute difference between postoperative electrocochleography (ECochG) thresholds and postoperative behavioral thresholds at 125, 250, and 500 Hz frequencies are shown in the overall cohort.

Frequency (Hz)	Δ Postop ECochG and postop behavioral thresholds, overall mean in dB HL (range)	Δ Postop ECochG and postop behavioral thresholds, ST insertion mean in dB HL (range)	Δ Postop ECochG and postop behavioral thresholds, SV insertion mean in dB HL (range)	p-value
125	15 (0–37)	7 (0–14)	22 (15–37)	0.0007
250	9 (0–23)	8 (4–14)	11 (0–23)	0.42
500	6 (0–29)	4 (1–11)	6 (0–13)	0.99

Differences are also depicted according to scalar location of the electrode array; the P-value represents the comparison between scala tympani (ST) insertions and scala vestibuli (SV) insertions. Means and ranges are reported. Bonferroni correction is applied for multiple comparisons, with p < 0.017 indicative of statistical significance.
