Various objective measures of change in cochlear microphonic (CM) amplitude during insertion are compared between scala tympani (ST) and scala vestibuli (SV) insertions.
| Δ CM Amplitude during insertion | ST Insertion median in dB (range) | SV Insertion median in dB (range) | p-value |
|---|---|---|---|
| Round window to peak amplitude | 25 (16–40) | 19 (5–33) | 0.35 |
| Peak amplitude to complete insertion | 5 (0–8) | 3 (0–5) | 0.61 |
