The microvascular decompression is major brain surgery done under general anesthesia through an incision behind the ear. The procedure is done for more than one type of disorder. Most neurosurgeons monitor the function of the patient’s facial nerve and hearing during the operation.
The goal of microvascular decompression surgery is to find the culprit vessel(s) that is compressing the cranial nerve and move it. If any artery is compressing the nerve, padding can be placed between the nerve and the artery to hopefully prevent the artery from hitting the nerve in the future. If a vein is found, padding can be placed between it and the nerve or the nerve can be cauterized. It is not uncommon to find more than one culprit vessel when exploring the nerve.
Studies have proven neurosurgeons that do more microvascular decompression surgeries tend to have better results and hospitals that have surgeons who do more procedures tend to have better results for the patients. Ten microvascular decompressions a year is a reasonable number of microvascular decompression’s done by a neurosurgeon. Ten, twenty, thirty or even more microvascular decompression’s being done at a hospital each year is practical.
Microvascular decompression patients with classic symptoms have an 80-90% chance of obtaining pain relief which is usually immediate. This procedure provides the least chance of the pain returning.
