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 electronenrography (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 _firing fibres can allow
us to estimate prognosis of Bell's palsy, If we make serial tests. |
