Summary

Gamma Knife radiosurgery offers a safe alternative to skull base surgery, preserving cranial nerve function and achieving tumor growth arrest. It serves as an effective adjuvant therapy for residual tumor volumes after partial resection.

Area of Science:

  • Neurosurgery
  • Radiation Oncology

Background:

  • Skull base surgery aims for total tumor resection but carries significant risks to critical cranial structures.
  • Aggressive resection can lead to severe neurological deficits, including vision, hearing, and cranial nerve dysfunction.

Purpose of the Study:

  • To evaluate Gamma Knife radiosurgery as a primary or adjuvant treatment for skull base tumors.
  • To assess the efficacy and safety of radiosurgery in preserving neurological function and controlling tumor growth.

Main Methods:

  • Gamma Knife radiosurgery as a primary treatment option.
  • Adjuvant radiosurgery following partial tumor resection for larger tumors.

Main Results:

  • Radiosurgery minimizes risks associated with open surgical techniques.

  • Preserves existing cranial nerve function in the majority of patients.
  • Achieves tumor growth arrest and long-term tumor volume control.

    • Conclusions:

    • Gamma Knife radiosurgery is a viable and effective alternative for skull base tumors, especially when surgery poses high risks.
    • It offers a less invasive approach, preserving neurological function and providing durable tumor control.
