First of all I do all of my cosmetic surgery at North Texas Hospital which is on the very southern border of Denton on I-35 East. This a partially physician owned hospital of which I am one of the physician owners. I do not use a nurse anesthetist to put you asleep, I only use board certified anesthesiologists and therefore I virtually have no anesthetic problems. This is something many people aren't aware of and it should be one of the first questions asked to the plastic surgeon. Also, if someone either requests or needs to stay overnight there are mostly Intensive Care trained nurses on hand to take care of your every need.
All of my breast augmentation procedures are done "under the muscle". I use either Mentor saline or memory gel (silicone gel) implants depending on the wishes of the patient and my recommendations due to anatomical factors. Usually the incision is in the fold or crease below the breast. For saline implants the incision is less than 2 inches and for silicone gel implants is slightly longer. I use other approaches to place the implants such as around the areola (around the nipple region) or in the armpit (axilla area), but these incisions are much more visible. I don't use drains. Complications are rare. It's a great procedure with almost instant satisfaction!
