Immediate and Long-Term Outcomes of Microvascular Decompression for Mixed Trigeminal Neuralgia.

World Neurosurg 2018 Sep 12;117:e300-e307. Epub 2018 Jun 12.

Department of Neurosurgery, Johns Hopkins Medicine, Baltimore, Maryland, USA.

Background: Classic trigeminal neuralgia (TN) involves sharp, shooting pain in any trigeminal nerve distribution, whereas atypical TN presents with constant aching, numbness, or burning that can appear with classic features, leading to a mixed presentation. Microvascular decompression (MVD) is an effective treatment for classic TN, but its utility in treating mixed TN has been less well studied.

Methods: We retrospectively studied 73 adult patients with mixed TN and 386 patients with classic TN who underwent MVD between December 2007 and October 2016. Read More
