Endoscope-assisted microvascular decompression (MVD) improved outcomes for patients with cranial nerve disorders. This technique enhanced visualization and confirmed adequate decompression, leading to symptom relief.

Area of Science:

  • Neurosurgery
  • Minimally Invasive Surgery
  • Neurology

Background:

  • Microvascular decompression (MVD) is a standard treatment for cranial nerve compression syndromes.
  • Limitations in surgical visualization can impact the completeness of decompression.
  • Endoscopic techniques offer potential advantages in surgical clarity.

Purpose of the Study:

  • To evaluate the efficacy of endoscope-assisted microvascular decompression (MVD) for cranial nerves V, VII, and VIII.
  • To assess the role of neuroendoscopy as an adjunct to the surgical microscope in MVD procedures.
  • To determine the impact of this combined approach on patient outcomes.

Main Methods:

  • A series of 28 consecutive patients underwent MVD for trigeminal (CN V), facial (CN VII), or vestibulocochlear (CN VIII) nerves.

  • Neuroendoscopy was employed alongside the surgical microscope to inspect neural anatomy and assess vascular compression.
  • Endoscope utility was graded, and its usefulness in visualizing compression and confirming decompression was evaluated.

    • Main Results:

    • The endoscope provided valuable visualization of anatomy in all cases, particularly in Meckel's cave and at the root exit zone.
    • It aided in identifying multiple compression sources and confirming adequate decompression, including cases where the microscope alone was insufficient.
    • In six patients with trigeminal neuralgia, endoscopic vision was critical for successful treatment of venous compression.

    Conclusions:

    • Endoscope-assisted MVD is a valuable adjunct for treating trigeminal neuralgia, hemifacial spasm, and vertigo/tinnitus caused by CN compression.
    • The enhanced visualization provided by the endoscope improves surgical precision and confirmation of decompression.
    • All patients in the study achieved asymptomatic status post-procedure.
