Our purpose is to investigate the electrophysiological characteristics of Bell's palsy
and to obtain clues for estimating prognosis in the late period by using
electroneurography (ENoG). Thirty patients were followed by ENoG over a period
of three months. They were evaluated through the forty full score system and
classified into three groups according to the degrees of facial nerve recovery. There
were significant differences between ENoG results of each group in the time course
between 1.5 and 3.0 months of onset. The effect of increasing intensity on the
amplitude is the most valid parameter for follow-up prognostic estimation. We
concluded that the amount of non-degenerated synchronous firming fibers can
allow us to estimate prognosis of Bell's palsy, if we make serial tests. |
