An ilioinguinal neurectomy is a procedure that is used to treat chronic groin pain. The procedure cuts the nerve in half to prevent the transmission of pain signals from the groin back to the brain. This may be accomplished surgically, with high intensity radio frequency ablation or by dissolving the nerve by injecting it with absolute alcohol. It has been used to treat patients with severe pain caused by hernia mesh. Some surgeons now are starting to do it prophylactically at the time of mesh hernia surgery to prevent the later development of severe chronic pain. We thinks it is better just to not use the mesh in the first place.
