Purely endoscopic microvascular decompression (MVD) of the trigeminal nerve offers a safe and effective approach. This technique enhances visualization, potentially improving outcomes for trigeminal neuralgia patients.

Area of Science:

Neurosurgery
Minimally Invasive Procedures
Endoscopic Techniques

Background:

Microvascular decompression (MVD) is a standard treatment for trigeminal neuralgia due to vascular compression.
Neuroendoscopes are increasingly used in skull base surgery.
Endoscopic adoption in posterior fossa lateral approaches has lagged, often serving as an adjunct to microscopy.

Observation:

This paper details a stepwise technical guide for purely endoscopic MVD of the trigeminal nerve using the retrosigmoid approach.
The endoscope provides superior visualization of the neurovascular relationship.
Full visualization of the trigeminal nerve is achievable.

Findings:

Endoscopic MVD allows for comprehensive visualization of the trigeminal nerve and surrounding structures.

This enhanced visualization may lead to increased MVD success rates.

A potential decrease in surgical complications is suggested.

Implications:

Endoscopic MVD is a safe and effective method for accessing the trigeminal nerve in the cerebellopontine angle.
The technique holds promise for broader application in neurosurgical and neuro-otological procedures, including cerebellopontine angle mass resections.
