title: [Usefulness of multimodal microscopic-based neuronavigation combined with intraoperative magnetic resonance imaging system in the treatment of lesions of middle skull base].
abstract: OBJECTIVE
  To evaluate the applicative value of multimodal navigation combined with intraoperative magnetic resonance imaging system in the treatment of complex lesions of middle skull base.
  
  
  METHODS
  Nineteen consecutive patients undergoing complex lesions resection using multimodal microscopic navigation combined with iMRI were included. Preoperative radiological images were imported into navigation planning system, based on which approach and microsurgical window were designed. Transcranial approach and extracranial approach(include trans-oral-nasal-sphenoidal approach and transsphenoidal approach) were performed in our series. After presumptively total resection were finished, intraoperative magnetic resonance (iMRI)were performed, followed by navigation images updating, and continuing resection if necessary.
  
  
  RESULTS
  iMRI scan were performed from 1 time to 2 times. In 5 cases with residual seen on iMRI scan, continued resection were carried on in 2 of them. There was no iMRI-associated complications.
  
  
  CONCLUSIONS
  Microscopic-based neuronavigation, in combination with intraoperative magnetic resonance, could provide objective basis for resection, and improve the safety level of tumor resection.
