The actual recovery from either approach is the same. The decision of one over the other has to do with many factors, including surgeon experience, rates of altered nipple sensibility, capsular contracture rates,size of the implant being considered, and baseline breast anatomy. Typically, most surgeons in this country use an IMF incision. Studies have shown that there is a lower chance of altered nipple sensibility and capsular contraction rates with the IMF approach. Also, in the event that another procedure is required for any reason, the surgeon can usually go back through the same scar as opposed to creating a second scar if a previous periareolar approach was used. I recommend being seen by a board certified plastic surgeon who performs many breast and body procedures to examine you and discuss your goals and objectives.Best wishes,Dr, Ravi Somayazula
