Area of Science:

  • Neurosurgery
  • Minimally Invasive Procedures
  • Surgical Visualization

Background:

  • Hemifacial spasm (HFS) significantly impacts quality of life.
  • Microvascular decompression (MVD) is a primary treatment for HFS.
  • The role of endoscopy as an adjunct in MVD for HFS requires further clarification.

Purpose of the Study:

  • To review the literature on endoscopic use in MVD for HFS.
  • To describe a simultaneous microscopic and endoscopic visualization technique.
  • To evaluate the efficacy of this combined approach.

Main Methods:

  • Retrospective review of 21 patients undergoing MVD for HFS (2011-2019).
  • Comparison of traditional endoscopic-assisted visualization with a novel simultaneous endoscopic/microscopic technique.
  • Surgical technique detailed and illustrated with video.

Main Results:

  • Immediate symptom resolution in 20/21 patients.
  • Recurrence in 7 patients, with spontaneous resolution in 4 and redo MVD in 3.
  • Transient complications in 29% of patients, all fully resolved.
  • No significant difference in outcomes between visualization techniques.

Conclusions:

  • Endoscopic assistance is beneficial for MVD in HFS.
  • The simultaneous microscope and endoscope technique streamlines visualization.
  • This approach may enhance the efficiency and effectiveness of MVD for HFS.
