Hello and thank you for your question. In short- every surgeon's practice is different. Regarding the anesthesia- although most surgeons prefer putting patients fully asleep under general anesthesia for this procedure, some perform it under IV sedation ("twilight sedation") with local anesthesia, or just under straight local sedation, as you are describing here. Generally, most patients would not tolerate such an invasive procedure done under local, and most surgeons feel that it is easier to perform such involved and complex procedures with patients at least sedated if not fully asleep so they can assure the patient remains perfectly still. Everything ultimately comes down to surgeon and patient preference, so always have the conversation with your surgeon so you both know exactly what to expect, and so you both feel comfortable with how the procedure will be performed prior to proceeding. I hope this helps!
