Summary
Adding endoscopy to microvascular decompression for trigeminal neuralgia significantly improved visualization, identifying overlooked vessels and leading to high pain relief rates with a comparable complication profile.
Area of Science:
- Neurosurgery
- Surgical Technology
Background:
- Microvascular decompression (MVD) is a primary treatment for trigeminal neuralgia (TN).
- Surgical limitations in visualizing the trigeminal nerve root entry zone can lead to MVD failure.
- Microscope visualization alone may not always achieve complete decompression.
Observation:
- A retrospective review of 114 patients undergoing MVD for TN was conducted.
- An endoscope was used to inspect the trigeminal nerve root entry zone before surgical closure.
- Endoscopic inspection identified vessels missed or poorly visualized by microscopy in 33% of patients.
Findings:
- Endoscopy successfully visualized the trigeminal nerve in 113 of 114 patients.
- Complete pain relief was achieved in 99.1% of patients at a mean 29-month follow-up.
- The overall complication rate was 9%, including trigeminal dysesthesias and hearing loss.
Implications:
- Endoscopy enhances visualization during MVD for TN, improving identification of causative vessels.
- This adjunct increases the likelihood of successful nerve decompression and high pain relief rates.
- Endoscopic MVD offers a safe and effective approach with outcomes comparable to traditional methods.
