EMG systems assist the surgeon to locate, identify, and confirm the functional integrity of the facial nerve. The Brackmann II EMG Monitoring System is an integrated unit with both monitoring and stimulating functions.

Bipolar hooked-wire needle electrodes are placed in two branches of the patient's facial muscles to detect electrical motor end-plate activity. Constant-current, pulsed stimulation is delivered with a monopolar or bipolar single-use probe.

The bar-graph display and audio feed back system provide immediate and distinct feedback to the surgeon. Electrocautery suppression is delivered with a mute sensitivity feature.
