title: [Peripheral facial paralysis. The value of clinical neurophysiology].
abstract: OBJECTIVE
  The aim of this study was to review the value of neurophysiological exploration in peripheral facial paralysis in the literature and in our own experience.
  
  
  METHODS
  Peripheral facial paralysis is a frequently occurring cranial neuropathy with an acute presentation. Its striking clinical expression is usually in strong contrast to its benign prognosis, except for a small percentage of cases in which the existence of acute injury to the nerve (axonotmesis) will cause it to progress unfavourably, either due to the absence of nerve regeneration or because this is inadequate or insufficient. A neurophysiological study aids diagnosis and the functional and prognostic assessment.
  
  
  CONCLUSIONS
  We recommend the utilisation of standardised studies involving a comprehensive electromyographic and electroneurographic evaluation of the facial territory, including reflexology (blink reflex). Use of a suitable methodology in the neurophysiological study of this neuropathy will allow us to complete the diagnosis and to evaluate progress, even from very early days (early surgical approach prior to the onset of nerve degeneration), all of which is decisive in the prognosis of injury throughout the process.
