The RobOtol​ system in clinical applications – our first clinical experience with the robot-assisted insertion of CI electrodes with simultaneous cochlear monitoring

Introduction 

The RobOtol​ system (from Collin) is the first commercially available robot for the assisted insertion of CI electrodes. Initial clinical studies have shown that robot-assisted electrode insertion can reduce surgical trauma. We report on our first clinical experiences with the RobOtol​ system.

Methodology

We carried out a retrospective study on patients in whom we used the RobOtol​ system and performed simultaneous cochlear monitoring. The RobOtol​ system is an instrument holder arm that is controlled with a joystic and has the following 7 degrees of freedom: 3 rotations, 3 translations and a z-axis movement. Using specific instruments, the electrodes of the various manufacturers can be grasped and inserted very slowly into the cochlea and stopped at any time.

Results 

The robot-assisted electrode insertion was carried out successfully in all cases. The cochlear monitoring could be derived simultaneously. Postoperatively, the position in the Tympani scale was documented by means of DVT. Due to the instruments available, insertion is currently limited to straight electrodes.

Conclusions

We were able to insert the electrodes safely and atraumatically using the robot-assisted insertion. The development of specific instruments for the insertion of preformed electrodes is in planning.
