Surgical technique management of microvascular decompression for trigeminal neuralgia.

Trigeminal neuralgia is a severe neuropathic disorder, affecting the distribution area of the trigeminal nerve and often impairs the quality of life of patients. More and more scholars agree that one of the pathogenesis of trigeminal neuralgia is due to the demyelinating lesion caused by vascular compression or arachnoid bundle wrapping on the root exit zone of trigeminal nerve. In this regard, the most effective method is microvascular decompression, which can relieve the compression of the offending vessels and the thickened arachnoid on the trigeminal nerve. However, it still has some disadvantages, such as the possibility of fatal complications. In recent years, with the advancement of neurosurgical treatment technology, new progress has been made in microvascular decompression. This article mainly introduces the surgical techniques and new methods of the microvascular decompression.
