Trigeminal Nerve Isolation Application in Microvascular Decompression for Treating Trigeminal Neuralgia: A...

Area of Science:

• Neurosurgery
• Neurology

Background:

• Trigeminal neuralgia (TN) is a chronic pain condition affecting the trigeminal nerve.
• Conventional microvascular decompression (CMVD) is a standard surgical treatment for TN.
• Trigeminal nerve isolation (TNI) is an alternative surgical approach.

Purpose of the Study:

• To compare the surgical outcomes of trigeminal nerve isolation (TNI) versus conventional microvascular decompression (CMVD) in patients with trigeminal neuralgia (TN).

Main Methods:

• A retrospective review of 143 TN patients who underwent microvascular decompression between January 2017 and January 2020.
• Patients were randomized into two groups: TNI and CMVD.
• Outcomes, including pain relief, recurrence rates, and complications, were assessed after at least a 1-year follow-up.

Main Results:

• No significant differences in general data, hospitalization duration, or blood loss were observed between TNI and CMVD.
• Recurrence rates were lower after TNI (5.5%) compared to CMVD (17.1%).
• Pain relief rates were 94.5% for CMVD and 82.9% for TNI, with TNI showing better outcomes in difficult cases.

Conclusions:

• Trigeminal nerve isolation (TNI) appears to be more effective than conventional microvascular decompression (CMVD) for treating trigeminal neuralgia (TN).
• TNI demonstrated a lower recurrence rate and superior efficacy in challenging surgical cases.
• Further randomized controlled trials are warranted to validate these findings.
