Neurosurgery·2026

Radiosurgery uses focused radiation for minimally invasive treatment of brain and body lesions. This technique has evolved into a mainstream neurosurgical modality with established long-term efficacy for various disorders.

Area of Science:

  • Neurosurgery
  • Radiation Oncology
  • Medical Physics

Background:

  • Radiosurgery is a minimally invasive technique using focused ionizing radiation for targeted tissue response.
  • Originally developed for intracranial lesions with stereotactic guidance, it was defined by Lars Leksell.
  • Advancements in stereotactic methods, dose planning, and neuroimaging have expanded its applications.

Purpose of the Study:

  • To review the evolution and current applications of radiosurgery.
  • To highlight its established role in treating brain disorders.
  • To discuss its emerging use in extracranial and body pathologies.

Main Methods:

  • Review of historical development and technological advancements in radiosurgery.
  • Analysis of studies examining the benefits and risks of various radiosurgical devices.

  • Evaluation of long-term results for established and emerging applications.

    • Main Results:

    • Radiosurgery is now a mainstream neurosurgical modality for conditions like vascular malformations, tumors, trigeminal neuralgia, movement disorders, and epilepsy.
    • Long-term results confirm its effectiveness as a noninvasive management strategy for many brain disorders.
    • Its application is expanding to extracranial lesions, including spinal tumors and pathologies in the lung, liver, and prostate.

    Conclusions:

    • Radiosurgery has evolved into a versatile and effective treatment modality.
    • It is a well-established option for numerous intracranial conditions.
    • Its role in spine and body surgery is under active evaluation and shows promise.
