Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Surgical Navigation

Background:

  • Frame-based stereotaxy involves a rigid ring attached to the skull for precise instrument positioning.
  • This method is crucial for deep-seated brain lesions, electrode placement, and brachytherapy.

Purpose of the Study:

  • To compare conventional frame-based and novel frameless neurosurgical localization and treatment methods.
  • To highlight the advantages of frameless procedures in terms of surgical approach, planning, and patient comfort.

Main Methods:

  • Discusses frame-based procedures utilizing intraoperative image localization and infrared-based digitization of surgical instruments.
  • Explains frameless procedures employing anatomical markers and surface matching for registration in preplanning software.

Main Results:

  • Frameless procedures eliminate the need for a head-mounted ring, allowing broader surgical approaches and improved logistics.
  • Frameless techniques simplify scheduling, enable multi-modal imaging for planning, and enhance patient tolerance.

Conclusions:

  • Frameless neurosurgical navigation offers significant advantages over frame-based methods.
  • These advancements improve surgical precision, patient comfort, and procedural efficiency in treating brain lesions.
