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

Abstract

Aberrant CSF dynamics may contribute to the pathogenesis of Type 1 TN without NVC. Preoperative phase-contrast MRI may aid in identifying candidates for surgery. Arachnoid dissection targeting abnormal CSF flow may represent a viable treatment option for patients with TN lacking visible NVC.
