The Bio-logic Navigator Pro AEP System with External SEP Stimulator Option supports Electroneuronography. It is helpful in the diagnosis & treatment of facial nerve paralysis. It gives a precise and objective measure of facial nerve integrity. The CPT Code for Electroneuronography is 92516. The EnoG test protocols are: Electrical stimulation of facial nerve should be done near mastoid mastoid with measurement of motor response recorded near naso-labial fold. Then, response of the amplitude of the abnormal side to that of the normal side is compared. The main function of External SEP Simulator is to provide consistent current pulses of brief duration for transcutaneous stimulation. The output current varies continuously over a range of 1 to 100 milliamps.
