title: [Alarming effect of intraoperative neuroelectrophysiological monitoring in microvascular decompression for primary trigeminal neuralgia].
abstract: OBJECTIVE
  To explore the alarming effect of intraoperative neuroelectrophysiological monitoring in microvascular decompression (MVD) for primary trigeminal neuralgia.
  
  
  METHODS
  In 2014, a total of 44 patients with an initial diagnosis of primary trigeminal neuralgia were consecutively recruited for surgery. And 41 of them with an intraoperative confirmation of primary trigeminal neuralgia underwent MVD. Intraoperative neuroelectrophysiological monitoring was employed for brainstem auditory evoked potentials (BAEPs), spontaneous electromyogram for obicularis oculi, obicularisoris and masseter muscles. The real-time alarming report was offered to the operator who adjusted operations accordingly.
  
  
  RESULTS
  There were abnormal changes in 23 cases (56.10%) with a total of 77 instances (BAEPs 27, trigeminal nerve 32, facial nerve 18). The outcomes were no facial pain (n=26), pain relief (n=15) and facial numbness (n=6, two with concurrent hearing disturbance). And the rates of facial pain disappearance and sequela occurrence were much better than those in controls without monitoring.
  
  
  CONCLUSIONS
  Intraoperative neuroelectrophysiological monitoring helps enhance the MVD effect and decrease operative squela through alarming reporting.
