The surface of breast implants can be smooth or textured, regardless of the filler material—silicone gel or saline. Sientra sells only silicone gel implants, but the other two USA breast implant manufacturers sell textured saline implants as well as silicone ones. When silicone gel implants were used prior to the FDA restrictions of 1992, placement above the muscle was also the preferred implant position for many plastic surgeons. Texturing the surface of the silicone gel implant reduced the incidence of capsular contracture in this position (above the muscle and just below the breast tissue). However, after the 1992 FDA restriction on silicone gel implants and the switch to saline-filled implants, placement above the muscle led to unacceptable wrinkling that could sometimes be felt or seen. This led to most surgeons switching to placement of saline breast implants below the muscle to increase tissue coverage and reduce these concerns. Even placement of saline-filled implants below the muscle will not always eliminate implant wrinkles or ripples, particularly in thin patients and/or patients with very little overlying breast tissue. Since 2006, silicone gel implants are again available for elective breast augmentation, allowing patients to avoid the “water-balloon” feel and visible or palpable rippling seen in some saline implant patients. Based on the choice of saline or silicone, textured or smooth, and the patient's unique body type, appropriate surgical placement will be determined. Many studies have confirmed lower capsular contracture rates with implant pockets below the muscle. However, using textured breast implants below the muscle can cause unnatural adherence to the chest and restricted natural movement of the breast, and is not recommended. In addition, saline implants lack cohesive silicone gel to act as a lubricant inside the implant (saline is a poor lubricant), and can allow flexing and creasing of the textured implant shell surface with each movement or breath of the patient, ultimately leading to a higher risk of failure at one of the low spots in the textured surface, with leakage and deflation of the saline implant. The textured implant shell is also thicker and more palpable. Submuscular placement already reduces the incidence of capsular contracture, so smooth breast implants in this location are preferable to adherent textured-surface implants. Smooth-shell silicone-gel-filled implants are homogeneous with breast tissue and provide the softest, most breast-like, and most natural “feel” of any implant. Since the newest generation of silicone gel implants is also cohesive, they cannot leak. While the vast majority of patients are again choosing submuscular silicone implants for their breast enhancement surgery, I believe that textured implants below the muscles offer no advantages, and possible disadvantages (plus they cost more and require a slightly longer incision).Choose silicone, smooth, and realize that round implants are teardrop shaped when the woman is standing, and flatten and round out (like natural breasts do) when reclining, whereas textured teardrop-shaped implants REMAIN teardrop-shaped when reclining (decidedly unnatural).
