>

Facial nerve safety – preliminary work —

Neuromonitoring for FN protection (detect FN proximity)

Optimal stimulation protocol determined in sheep

Custom neuromonitoring probe detects FN (<0.1 mm)

Project Goal —

Cathode

Drill integrated stimulation for conitinuous FN monitoring Anode 3 Anode 2 Anode 1

Proposal — — —

>

Drill passes within 0.3 – 1 mm of facial nerve

Protocol verification in humans (medical grade EMG device required) (Neurosign device, 17000 CHF )

FN

Drill bit insulation coating for integrated stimulation electrodes (Student 2.5 months ~ 14,000 CHF) Total budget 31,000 CHF, project duration 6 months
