Objective:
To investigate the disturbance induced in the cochlea during cochleostomy using conventional drill and a hand guided robotic drill.
Study Design:
The study is based on experimental measurements using the Laser Doppler Vibrometer during the drilling processes converted to Sound Pressure Levels (SPL) for comparison.
Setting:
The study is based on experimental results of three sets of cochleostomies on human cadaver heads.
Main Outcome Measure(S):
Robotic drilling, in comparison to the conventional drilling method, creates a consistently lower level of disturbance in cochlea across the hearing frequency range.
Results:
Robotic drilling, in comparison to the conventional drilling method, creates a consistently lower level of disturbance in cochlea across the hearing frequency range.
Conclusions:
It is reasonable to conclude that robotic drilling has a lower possibility of creating acoustic trauma in cochlea that endangers the residual hearing of patients.
