Insights

Microvascular decompression (MVD) is a safe and effective treatment for trigeminal neuralgia (TN) in elderly patients. This study found no significant differences in outcomes or complications compared to younger patients, supporting MVD for all age groups.

Area of Science:

  • Neurosurgery
  • Neurology

Background:

  • Microvascular decompression (MVD) is the primary etiological treatment for trigeminal neuralgia (TN).
  • Concerns exist regarding increased surgical risks in elderly patients undergoing MVD for TN.
  • This study evaluates MVD outcomes in elderly TN patients.

Purpose of the Study:

  • To analyze the surgical and clinical outcomes of MVD in elderly patients with trigeminal neuralgia.
  • To compare outcomes between elderly (≥65 years) and non-elderly (<65 years) TN patients undergoing MVD.

Main Methods:

  • Retrospective single-center study of 76 TN patients who underwent MVD (April 2018 - April 2022).
  • Patients were divided into elderly (n=25) and non-elderly (n=51) groups.
  • Outcomes assessed included acute pain relief (APR), Barrow Neurological Index (BNI), complications, and recurrence. Multivariate analysis (Cox regression) was performed.

Main Results:

  • No significant differences were observed between elderly and non-elderly groups in APR, BNI, complications, or recurrence rates.
  • The presence of an offending artery causing nerve root distortion/indentation was the sole independent predictor of pain-free survival (p=0.0001).

Conclusions:

  • Microvascular decompression is a safe and effective treatment for trigeminal neuralgia, even in elderly patients.
  • Age is not a significant factor influencing MVD outcomes or complication rates in TN patients.
  • Identifying an offending artery is crucial for predicting long-term pain relief in TN patients treated with MVD.
