2 pointsI have not had this procedure but did have the trigiminal nerve cut down at the Mayo Clinic back in 1982. I was part of this study; https://www.ncbi.nlm.nih.gov/pubmed/12707445 There was 17 in the study. Lots of problems, they don't do it any longer. Stick with mm. I'm not sorry I had it done , it saved my life . Would not advise anyone have surgery . A true believer in busting.
