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.
