In this system, grades I and II are considered good outcomes, grades III and IV represent moderate dysfunction, and grades V and VI describe poor results. Grade VI is defined as complete facial paralysis; all of the other grades are defined as incomplete. An incomplete facial paralysis denotes an anatomically and, to some degree, functionally intact nerve. The degree of facial nerve function should be noted in the chart at the patient’s initial visit.
