Area of Science:

  • Neurosurgery
  • Minimally Invasive Surgery
  • Surgical Technology

Background:

  • Endoscopic surgery is increasingly used in neurosurgery for its detailed visualization.
  • A significant drawback is the intracranial blind area, risking neurovascular injury.
  • This study introduces a novel technique to address this limitation.

Observation:

  • The multiscope technique integrates endoscopic and exoscopic systems with dual monitors.
  • Microvascular decompression (MVD) is performed using an exoscope to cover the endoscope's blind spot.
  • Surgeons view both high-definition monitors simultaneously.

Findings:

  • Two patients with hemifacial spasm underwent successful endoscopic MVD using the multiscope technique.
  • Both endoscopic and exoscopic views provided excellent visualization.
  • No surgery-related complications were observed in the treated patients.

Implications:

  • The multiscope technique enhances safety in neuroendoscopic procedures compared to conventional methods.
  • This approach is adaptable to other skull base surgeries.
  • It offers a promising solution for improving visualization and safety in complex neurosurgical operations.
