Colorectal surgeon vs plastic surgeon: external reconstruction

A perfect storm left a variety of damage after my second (and last) vaginal delivery. My Urogynecologist referred me to a Colorectal Surgeon to first correct internal rectal damage. I am booked for triple hemorrhoidectomy on 8.12 The surgeon also offered to remove loose tissue and external scar tissue. He said he hoped to achieve 95% return to visual normalcy in reconstruction of the anus. He will also look at an internal perineal wall fissure. Should I somehow request a plastic surgeon?
