Introduction.
To preserve residual hearing the atraumaticity of the cochlea electrode insertion has become a focus of cochlear implant research.
In addition to other factors, the speed of insertion is thought to be a contributing factor in the concept of atraumatic implantation.
The aim of our study was to observe intracochlear fluid pressure changes due to different insertional speeds of an implant electrode in a cochlear model.
Materials and Methods.
The experiments were performed using an artificial cochlear model.
A linear actuator was mounted on an Advanced Bionics IJ insertional tool.
The intracochlear fluid pressure was recorded through a pressure sensor which was placed in the helicotrema area.
Defined insertions were randomly performed with speeds of 0.1 mm/sec, 0.25 mm/sec, 0.5 mm/sec, 1 mm/sec, and 2 mm/sec.
Results.
A direct correlation between speed and pressure was observed.
Mean maximum values of intracochlear fluid pressure varied between 0.41 mm Hg and 1.27 mm Hg.
Conclusion.
We provide the first results of fluid pressure changes due to insertional speeds of CI electrodes in a cochlear model.
A relationship between the insertional speed and intracochlear fluid pressure was observed.
Further experiments are needed to apply these results to the in vivo situation.
