Microvascular decompression surgery (MVD) is intended to address the root cause of the pain or symptoms by moving the offending vessel off the cranial nerve by creating a cushion or pad between the nerve and vessel.
This approach involves a keyhole retromastoid craniotomy made through a small incision behind the ear. Through this opening and using a high-definition endoscope or microscope, small pads of Teflon are placed between the nerve and vessel to “decompress” the nerve and allow it to function normally.
With this technique there is little or no need for brain retraction or nerve manipulation. The procedure takes about 3 hours and most patients are in the hospital for two nights after surgery.
