Electroneurography (ENoG) values are used to assess the prognosis of facial nerve palsy. The ENoG value is the ratio of facial nerve degeneration on the paralyzed side to that on the healthy side. However, the measurement method is not presently standardized in Japan.
In this paper, the measurement method and prognostic diagnosis standard of ENoG are explained with a case. The recording position is important for determining the exact compound muscle action potential value.
Regarding stimulation, the cathode of the stimulation electrode is placed close to the stem mammary pore, and the anode is installed on an extension line connecting the cathode and the lateral angle of the eye, and the current amount stimulates 40 mA as a guide. In addition, the ENoG values must be calculated while paying attention to the artifact, and the prognosis can be determined more accurately using the prognosis judgment criteria.
