Background:
We describe our experience of the MVD in the typical trigeminal neuralgia and identify the prognostic factors.
Method:
A retrospective studio of 89 cases between 1995-2005 was used. The prognostic significant data evaluated were demographics data; duration of neuralgia; the affected divisions involved; surgical findings; used material for the decompression. The data analysis was made with the chi(2) test.
Results:
We have found an excellent outcome in 77% one year later. The age and the antecedent of hypertension disease were not statistically significant. A poor outcome was observed for: female sex, neuralgia lasting longer than two years, the three divisions involved, venous compression and the muscle used as surgical material.
Conclusions:
The MVD is an effective and reliable technique. The use of muscle is not recommended. When the three trigeminal divisions are involved we should choose another technique.
Insights
Microvascular decompression (MVD) offers excellent outcomes for trigeminal neuralgia. Factors like female sex and longer neuralgia duration predict poorer results, suggesting alternative treatments may be needed.
Area of Science:
- Neurosurgery
- Neurology
- Medical research
Context:
- Trigeminal neuralgia is a debilitating condition affecting facial nerves.
- Microvascular decompression (MVD) is a surgical treatment option.
- Identifying prognostic factors for MVD outcomes is crucial for patient management.
Purpose:
- To evaluate the effectiveness of Microvascular Decompression (MVD) for typical trigeminal neuralgia.
- To identify prognostic factors influencing MVD outcomes in trigeminal neuralgia patients.
Summary:
- A retrospective study of 89 trigeminal neuralgia patients undergoing MVD between 1995-2005 was conducted.
- Excellent outcomes were observed in 77% of patients one year post-surgery.
- Poor outcomes were associated with female sex, neuralgia duration over two years, involvement of all three trigeminal divisions, venous compression, and the use of muscle grafts.
Impact:
- Microvascular decompression is confirmed as an effective and reliable treatment for trigeminal neuralgia.
- The use of muscle grafts during MVD is not recommended.
- Alternative surgical techniques should be considered when all three trigeminal divisions are affected.
