Surgical variation of microvascular decompression for trigeminal neuralgia: A technical note and anatomical study.

BACKGROUND

In this article, the authors described their experience in microvascular decompression for trigeminal neuralgia.

METHODS

The microvascular decompression technique used in the authors' institution is described in a step by step manner with some illustrative cases as well as a cadaver dissection to highlight the differences with other previously described techniques.

RESULTS

Since 2013, 107 patients were operated in the Neurosurgery Division of the University of São Paulo using the described technique, with a shorter operative time and avoiding cerebellar retractor compared with classic techniques.

CONCLUSION

Our modified microvascular decompression technique for trigeminal neuralgia can be used with safety and efficiency for treating trigeminal neuralgia.
