Area of Science:

  • Neurosurgery
  • Head and Neck Oncology

Background:

  • Cranial base surgery is an emerging field addressing previously untreatable skull base tumors.
  • New surgical approaches and reconstruction techniques facilitate en bloc resection of complex tumors.

Purpose of the Study:

  • To analyze the 40-year evolution of cranial base surgery.
  • To assess its impact on treating skull base carcinomas and sarcomas.

Main Methods:

  • Literature review of outcomes over four decades (1960s-1990s).
  • Categorization into three distinct periods based on surgical advancements.

Main Results:

  • First period (1960s-1970s): 52% 3-year and 49% 5-year survival for tumors without extensive invasion.
  • Second period (1970s-1980s): Improved techniques led to 57-59% 3-year survival for more extensive tumors.
  • Third period (1980s-1990s): Refined techniques and multispecialty approach increased 5-year survival to 56-70%.

Conclusions:

  • Cranial base surgery has demonstrated progressive improvement in patient survival.
  • Advancements in surgical techniques and collaborative care are key to successful skull base tumor treatment.
