I'm beginning the process of seeking top surgery and I want to preserve nipple sensation. Does anyone have experience with peri-areolar, inverted T, etc. with larger chest (DD/E)? I would like to avoid double incision with nipple grafts because of the sensation loss.

Good question! Have you looked into the Buttonhole method?

Ask the surgeon(s) you consult with about doing a staged approach. (In other words, expect revisions to get the final results you seek.)
Hope this helps!
