Microvascular Decompression surgery is a medical procedure that is often done to provide pain relief that is associated with the trigeminal neuralgia. Trigeminal Neuralgia is caused when the fifth cranial nerve is irritated. This will result in the individual experience severe pain, usually on one side of the face.
Generally when Microvascular Decompression is used to treat trigeminal neuralgia, the skull is opened where the trigeminal nerve is located. Doctors will place a small sponge between the nerver and either the petrosal vein or cerebellar artery. This sponge will remove any compression the vessels may cause on the nerve.
