title: [Experimental and clinical study on intraoperative monitoring of facial nerve].
abstract: OBJECTIVE
  The aim of the study is to determine parameters that be predictive of function of facial nerve after facial nerve decompression surgery.
  
  
  METHODS
  Fifteen New Zealand white rabbits (30 facial nerves) and 21 patients with peripheral facial paralysis were monitored intraoperatively during facial nerve decompression surgery. These patients were followed up for at least 6 months.
  
  
  RESULTS
  Threshold of EMG is a steady parameter of assessing the function of facial nerve. The threshold between different segments of facial nerve has no difference in New Zealand white rabbits. That there exist EMG events were correlated significantly with good postoperative facial nerve function.
  
  
  CONCLUSIONS
  Threshold of EMG can be used as objective and steady parameter that assess the function of facial nerve. Intraoperative monitoring events can be used for assessment of postoperative facial nerve function.
