The application value of low frequency pulse electrodiagnosis in the assessment of facial nerve paralysis

Abstract

Objective To explore the value and significance of low frequency pulse electrodiagnosis to assess facial nerve paralysis.Method Neuromuscular electrical diagnostic instrument was used to detect curves of time intensity for frontalis muscle,orbicularis oculi muscle,orbicularis oris muscle in 50 cases of facial nerve paralysis,150 curves in all.Results In 50 cases of facial nerve paralysis,there were 7 normal patients,31 cases of part degeneration,12 cases of complete degeneration,with the positive rate of 86％.Among 150 curves of time intensity,there were 2l normal curves,96 curves of part degeneration,33 curves of complete degeneration,with the positive rate of 86％.Conclusion It has a certain value and significance of low frequency pulse electrodiagnosis for facial nerve paralysis evaluation.
