Because of a number of techniques I use during breast augmentation surgery, including the use of the Keller Funnel, that are outlined below, I see very few capsular contractures in my breast augmentation patients. However, the reality is that if you are a breast augmentation patient with a capsular contracture, the incidence - at least to you - feels like 100%. A well-established capsular contracture can be corrected, but doing so involves a return to the operating room, removing and discarding the implant, removing or excluding the contracted capsule, creating a completely new implant space, and putting in a new breast implant (that statement may be somewhat controversial, but I believe the procedure just described is what is what provides a patient with the lowest risk of recurrent contracture). So I think that surgeons should feel obliged to do everything possible to limit the likelihood that a patient develops this frustrating postoperative problem.
Studies have shown that a bacterium called Staph epidermidis can be cultured from as many as 70% of capsule specimens obtained during surgical procedures for capsular contracture. So I employ a number of measure that address the possibility that skin bacteria or nipple duct bacteria may adhere to the implant surface during the augmentation procedure. We prep the skin using potent antiseptic solutions prior to draping the surgical site with sterile drapes, however the microscopic surface of the skin is full of peaks and valleys, and `nooks and crannies' - like sweat glands, hair follicles and sebaceous glands - that may harbor bacteria despite thorough application of an antiseptic prep solutions.
After prepping, we apply a new skin sealant product called InteguSeal to the skin surface where the incision is to be made. This effectively seals off all of the `nooks and crannies' that may harbor bacteria, and the sealant lasts for several days postop. We also apply it over the nipple and areola to seal off the nipple ducts which may also harbor bacteria.
Over the course of the surgery, we irrigate the implant space several times with a large volume of a saline solution containing three antibiotics (which can be modified in patients with an allergy to any of the antibiotics in the solution). Prior to implant placement, we irrigate the implant space with full-strength Betadine, a potent topical antiseptic that has been shown in clinical studies to reduce the incidence of capsular contracture.
I think one of the greatest advances in reducing the possibility of implant contamination by skin bacteria during breast augmentation surgery is the development of a soft, sterile, paper funnel for insertion of silicone gel implants into the implant pocket. This simple yet clever device actually looks much like a pastry chef's bag. It allows me to introduce the implant into the subpectoral pocket without ever touching it with my gloves, and without the implant ever contacting the patient's skin surface. The implant package is opened, the implant is irrigated with antibiotic solution then `poured' into the funnel, the small end of the funnel is inserted in to the skin excision which is held open with retractors, and I gently `squirt' the implant into the pocket. Before this was available, there was a great deal of implant contact with the patient's skin, under great pressure, as a pre-filled gel implant is forced into the pocket through a relatively small incision. The implant insertion funnel completely eliminates what I think has been the most concerning aspect of breast augmentation surgery in regards to the potential contamination of the implant with bacteria during the procedure.
There is no breast augmentation practice with a capsular contracture rate of zero. Yet there are obviously a number of measures that can be taken to make the rate of contracture as low as possible. I think it is important for patients to have confidence that their surgeon is focused not only on providing a breast enhancement that is beautiful and natural-appearing, but also on maximizing the likelihood that their aesthetically pleasing result will remain beautiful and natural-appearing over the long term.
