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.
