Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Surgical Technology

Background:

  • Pituitary surgery historically carried significant risks.
  • Early diagnostic imaging of the sellar region emerged in the early 20th century.
  • Technological progress has been crucial in improving surgical outcomes.

Purpose of the Study:

  • To trace the historical development of sellar imaging for pituitary surgery.
  • To review the evolution of intraoperative imaging and guidance systems.
  • To evaluate the effectiveness and drawbacks of current intraoperative tools.

Main Methods:

  • Historical review of diagnostic and intraoperative imaging techniques.
  • Examination of the progression of image guidance systems.
  • Analysis of the utility and limitations of specific intraoperative aids.

Main Results:

  • Image guidance has substantially decreased morbidity and mortality in pituitary surgery.
  • Various intraoperative aids, including video fluoroscopy, frameless stereotaxy, ultrasound, and MRI, offer distinct advantages.
  • Each technology presents unique limitations that must be considered in surgical planning.

Conclusions:

  • Continuous advancement in imaging technology is vital for enhancing pituitary surgery safety and efficacy.
  • A comprehensive understanding of both historical and current imaging modalities is essential for neurosurgeons.
  • The selection of appropriate intraoperative guidance tools depends on the specific surgical context and patient needs.
