title: Microsurgical ressection for parasagittal meningiomas with preservation of the parasagittal sinus and excelent neurovascular control.
abstract: OBJECTIVE
  It was to observe whether a microsurgical gross total removal (GTR) of a parasagittal meningioma (PSM) outside the sinus is a safe and efficient procedure.
  
  
  METHODS
  We identify 58 parasagittal meningiomas patients. Medical charts, operative reports, imaging studies and clinical follow-up evaluations were reviewed.
  
  
  RESULTS
  GTR of the mass was achieved in 45 (77.7%) instances. The surgical mortality rate was 1.7%. The median follow-up time was 63 months.
  
  
  CONCLUSIONS
  The surgical approach used in this group of patients afford that the great majority of tumors could be totally removed with low mortality, proving to be safe and effective.
