Abstract:
Objective To evaluate the clinical application of nerve excitability test and stapedial reflex on the prognosis of facial nerve paralysis. Methods The threshold of excitability of the branches of facial nerves in both sides and stapedial reflex were tested in 50 patients.Results 34 patients out of 42 with differences of nerve excited threshold less than 3.5 mA showed complete recovery (81%),while only 2 patients out of 8 with the differences of nerve excited threshokd more than 3.5 mA showed recovery (25%), 32 patients out of 36 with positive response of stapedial reflex showed recovery (88.9%), but only 3 patients out of 14 recovered (21.4%) in non-response group.Conclusion The difference of nerve excited threshold of both sides less than 3.5 mA and positive response of stapedial refles showed a better prognosis, suggesting no severe injury to facial nerve and both nerve excitability test and stapedial reflex were useful chinical parameters to predict the prognosis of facial paralysis.
