title: Surgical options in the management of falcotentorial meningiomas: report of 13 cases.
abstract: BACKGROUND
  The primary aim of surgical treatment for falcotentorial meningiomas is gross total excision. The vital surrounding brain structures make this a complex task. Seeking elements that might facilitate presurgical planning we reviewed our surgical records of falcotentorial meningiomas treated during the past 20 years.
  
  
  METHODS
  Between 1975 and 1996, in the Neurosurgical Unit at the University of Rome, "La Sapienza," 13 consecutive patients underwent surgery for falcotentorial meningiomas that had been localized on preoperative imaging and confirmed by histology. The surgical approach varied according to the site of the tumor.
  
  
  RESULTS
  Nine meningiomas were totally removed and 4 subtotally. Three patients (23.0%), all treated early in the series, died after the operation. Ten patients (76.9%) survived: 3 (23.0%) had postoperative neurologic complications necessitating reintervention, and 7 patients (53.8%) had an uneventful postoperative course. Two of the 4 patients who had subtotal resections had regrowth at 1 year that responded to radiosurgery.
  
  
  CONCLUSIONS
  The ideal surgical approach to falcotentorial meningiomas should allow gross total removal and minimum brain retraction while safeguarding the galenic system and other vital neighboring structures. Toward achieving this aim we propose detailed preoperative imaging studies to classify falcotentorial meningiomas according to their site and direction of growth-craniocaudal or anteroposterior-in relation to the cerebellar tentorium.
