I have talked with tons of people treated by lots of different surgeons in different institutions that have had this procedure. Some have nerve damage, some do not. But I don't think that the many people that I have talked to with it are all victims of bad surgery. Different anatomical issues, and disease states of different extent and location with each patient, end up with the need to excise or even intentionally cut various nerves. Most were told AHEAD of time that this was a likely outcome, depending on what the surgeon encountered in process. I think that to call it an "error" is wrong. There are so many variables that that a generalization isn't fair.
