Summary
Microvascular decompression (MVD) offers superior long-term quality of life and pain relief for trigeminal neuralgia compared to stereotactic radiosurgery (SRS). MVD also shows lower complication and recurrence rates, making it the preferred treatment.
Area of Science:
- Neurosurgery
- Medical Technology
Background:
- Trigeminal neuralgia (TN) is a debilitating condition often treated with microvascular decompression (MVD) or stereotactic radiosurgery (SRS).
- Both MVD and SRS are effective for medically refractory TN, but optimal treatment selection and long-term outcomes remain debated.
- Patient selection for MVD versus SRS for TN requires careful consideration of durability and quality of life.
Purpose of the Study:
- To compare the long-term health-related quality of life (QOL) outcomes between MVD and SRS for trigeminal neuralgia.
- To determine which treatment modality, MVD or SRS, provides more durable pain relief and better QOL for TN patients.
- To utilize a decision-analytic model to quantify and compare the QOL associated with MVD and SRS.
Main Methods:
- A systematic literature search was conducted on PubMed and Cochrane Database for MVD and SRS in trigeminal neuralgia (2000-2015).
- A decision-analytic model was developed to simulate pain relief, complication rates, and QOL outcomes.
- Monte Carlo simulation was employed for sensitivity analysis to identify the procedure yielding the greatest QOL.
Main Results:
- Microvascular decompression (MVD) resulted in significantly higher QOL at seven-year follow-up compared to stereotactic radiosurgery (SRS).
- MVD demonstrated a higher rate of complete pain relief and a lower incidence of complications and recurrence.
- The decision-analytic model favored MVD for superior long-term outcomes in trigeminal neuralgia treatment.
Conclusions:
- Microvascular decompression (MVD) is associated with more favorable long-term outcomes than stereotactic radiosurgery (SRS) for trigeminal neuralgia.
- MVD provides superior quality of life, complete pain relief, and reduced complication/recurrence rates.
- Decision-analytic modeling supports MVD as the preferred treatment for medically refractory trigeminal neuralgia.
