Breast Augmentation is an ELECTIVE Surgery (you choose WHEN to do it (IE next Tuesday). It is not EMERGENT like a stab wound or ruptured appendix). It is COSMETIC (it is not necessary -- it is done to improve your appearance -- not your function). As such, the intolerance threshold for potential complications, in my opinion, should be very low. We should seek to make sure as much as we can that we reduce or eliminate known risks for a surgery that is NOT needed.
Capsular Contracture, bad scarring around implants, is KNOWN to be caused by multiple factors including: blood in the breast pocket, foreign bodies (glove powder, gauze fibers, small fibers from surgical gowns etc) in the pocket and infection. Infection can occur at the time of surgery - from germs who live on the skin coming in contact with the implant OR later on from germs in your blood stream "seeding" the implant forming a "BIOFILM" and causing a low grade infection followed by scar.
When you speak with orthopedic surgeons who do a lot of joints, most will NOT place a joint for fear of infections in anyone with an open wound. (I operated on a man with horrible knees whose orthopod would not do his knee replacement until I removed a scalp melanoma AND the wound was healed. The surgeon was fearful that a failed attempt at removal of that cancer would leave an open wound which MAY lead to infection of his joint.).
In your case, to quote that Great American - Clint Eastwood "How Lucky do YOU Feel?" You have open wounds and facial pustules. Does this mean that you would absolutely have capsular contractures if you had a breast augmentation now? Of course not. BUT -- is your risk of developing capsular contractures the same as someone who does NOT have open wounds and facial pustules? Of course not. You risk is higher.
You need to discuss this with a Plastic surgeon (www.PlasticSurgery.org) and understand what YOUR risk tolerance is.
