Intracochlear electric potential measurements for estimating electrode array position in cochlear implantation: The in vivo utility of an ex vivo model
The A<sub>scala</sub> at each electrode contact can be estimated using the TIM and Z<sub>fp</sub> measurements, which may help verify the correct alignment of the electrode array during the surgery. While the measured and predicted d<sub>EM</sub>s correlated with each other, there were significant differences between their absolute values. Given the large variation in d<sub>EM</sub>s for different array types, electrode-specific d<sub>EM</sub>s models could improve the accuracy of the predictions.
