title: Microsurgery on foramen magnum meningioma with suboccipital.
abstract: OBJECTIVE
  To analyze which factors influence the operative outcome, and compare advantages and disadvantages of relative surgical approaches.
  
  
  METHODS
  Eleven cases with the foramen magnum meningioma were operated by using posterior approach with lateral extension.
  
  
  RESULTS
  Complete removal of the tumor was performed in 7 patients (7/11, 64%), subtotal resection in 2 cases (2/11, 18%) and partial resection in 2 cases (2/11, 18%). There were no operative death and significant complication.
  
  
  CONCLUSIONS
  The posterior approach with lateral enlargement is sufficient to expose and remove foramen magnum tumors without expensive bone resection.
