Potential Role of Turbulent Cerebrospinal Fluid Flow in Type 1 Trigeminal Neuralgia Without Neurovascular Compression: Insights From a Cerebrospinal Fluid Dynamics Study

Key Points

• To explore how turbulent cerebrospinal fluid dynamics contributes to Type 1 trigeminal neuralgia without visible neurovascular compression.
• Conducted preoperative phase-contrast MRI to assess cerebrospinal fluid dynamics
• Targeted arachnoid dissection to correct abnormal cerebrospinal fluid flow
• Identified aberrant cerebrospinal fluid flow as a potential contributor to Type 1 trigeminal neuralgia
• Suggested that targeting this flow could improve surgical outcomes for patients without visible neurovascular compression
