Microvascular decompression (MVD) for trigeminal neuralgia (TGN) shows improved surgical outcomes with long-term follow-up. Advances in surgical techniques led to higher cure and satisfaction rates and lower recurrence rates in recent years.

Area of Science:

  • Neurosurgery
  • Neurology

Background:

  • Trigeminal neuralgia (TGN) is a debilitating condition characterized by severe facial pain.
  • Microvascular decompression (MVD) is a primary surgical treatment for TGN.
  • Long-term outcomes of MVD require continuous evaluation to assess treatment efficacy.

Purpose of the Study:

  • To evaluate the long-term surgical results of microvascular decompression (MVD) in patients with trigeminal neuralgia (TGN).
  • To compare outcomes between early and later surgical periods to identify trends in treatment success.

Main Methods:

  • Analysis of long-term follow-up data (5-20 years) from 281 patients with TGN who underwent MVD between 1976 and 2000.
  • Comparison of surgical outcomes between two groups: Group A (1976-1986) and Group B (1987-1991).

Main Results:

  • Postoperative cure rate increased from 92.9% in Group A to 96.7% in Group B.
  • Patient satisfaction rate increased from 80.3% to 82.5%.
  • Incomplete cure rate decreased from 7.1% to 3.3%, and recurrence rate decreased from 10.2% to 6.5%.

Conclusions:

  • Long-term follow-up confirms the effectiveness of MVD for TGN.
  • Improvements in surgical techniques likely contributed to the observed increase in success rates in later years.
  • MVD remains a highly effective treatment option for TGN with favorable long-term results.
