Microvascular decompression (MVD) is a type of neurosurgery used to treat trigeminal neuralgia (TN) caused by the vertebrobasilar contact/compression. The surgery is not risk-free, however; it may cause recurrent facial pain or other side-effects. The objective of this study was to assess the long-term pain relief and the complications of MVD surgery for the vertebrobasilar compression treatment.
