Area of Science:

  • Neurosurgery
  • Medical Technology
  • Surgical Navigation

Background:

  • Endoscopic neurosurgery offers minimally invasive approaches for various intracranial pathologies.
  • Frameless neuronavigation systems aim to improve precision and safety in complex surgical procedures.
  • Evaluating the utility of frameless neuronavigation in conjunction with endoscopic techniques is crucial for advancing neurosurgical practice.

Purpose of the Study:

  • To retrospectively analyze the indications, surgical techniques, and applicability of frameless neuronavigation in endoscopic neurosurgical procedures.
  • To assess the effectiveness of frameless neuronavigation in providing anatomical orientation and facilitating surgical approaches.
  • To evaluate the safety and outcomes associated with using frameless neuronavigation in a heterogeneous patient cohort.

Main Methods:

  • Retrospective analysis of 15 patients undergoing endoscopic neurosurgery with frameless neuronavigation.
  • Utilized two types of frameless neuronavigation systems: operating arm system (10 cases) and optical tracking system (5 cases).
  • Indications included cystic lesions (8 patients), intraventricular tumors (3 patients), and occlusive hydrocephalus (4 patients).

Main Results:

  • Frameless neuronavigation successfully provided anatomical orientation, preoperative planning, and intraoperative guidance in all 15 cases.
  • The mean calibration error for neuronavigation was 2.1 mm.
  • No permanent morbidities or mortalities were reported, indicating a safe application of the technology.

Conclusions:

  • Frameless neuronavigation is a valuable tool for endoscopic neurosurgery, particularly in selected cases requiring enhanced intraoperative orientation.
  • Ideal indications include small or hidden lesions, challenging visual conditions, abnormal anatomy, and narrow ventricles.
  • The technology supports procedures such as cyst fenestration/resection, tumor biopsy, and third ventriculostomy, improving surgical outcomes.
