Summary
Fully endoscopic microvascular decompression (MVD) offers a safe and effective treatment for trigeminal neuralgia (TN). This minimally invasive approach enhances visualization, leading to high rates of pain relief and low complication rates in patients with TN.
Area of Science:
- Neurosurgery
- Minimally Invasive Surgery
- Neurology
Background:
- Microscopic microvascular decompression (MVD) is a standard treatment for classical trigeminal neuralgia (TN).
- Endoscopy offers improved visualization in posterior fossa surgeries.
- Endoscopic MVD is emerging as an alternative for TN treatment.
Purpose of the Study:
- To evaluate the advantages and efficacy of fully endoscopic MVD for treating classical TN.
- To describe the operative technique for fully endoscopic MVD in TN patients.
Main Methods:
- A prospective study of 95 classical TN patients undergoing fully endoscopic MVD from January 2020 to January 2022.
- Surgeon and assistant operated with the assistant managing the endoscope.
- Intraoperative monitoring included Brain stem auditory evoked potentials (BEMPs).
- Postoperative outcomes assessed using Barrow Neurological Institute (BNI) pain intensity score.
Main Results:
- Immediate complete pain relief (BNI score I) in 97.9% of patients.
- Recurrence observed in 3.2% of patients within 12-36 months follow-up.
- Complications occurred in 5.3% of patients, including facial numbness and vertigo.
- No mortality, stroke, or hearing impairment reported.
Conclusions:
- Fully endoscopic MVD is a safe and effective treatment for TN.
- Enhanced visualization of neurovascular conflicts in the cerebellopontine angle (CPA) is a key advantage.
- This technique provides excellent outcomes with minimal complications.
