Abstract

In this study, changes in intracochlear pressure were measured against: varying speeds, depths; and level versus underwater insertions, of a dummy electrode array into an artificial cochlea. A deeper insertion was associated with greater pressure variation (0.059+/-0.007kPa versus 0.04+/-0.011kPa). The study also found that performing insertions underwater was associated with increased pressure variation (0.069+/-0.022kPa versus 0.03+/-0.003kPa). This study did not demonstrate a relationship between the speed of insertion and pressure variation. This study is currently the largest in-vitro study looking at intracochlear pressures. We hope it develops an understanding of key variables associated with soft surgical techniques.
