Paul Vitenas, Jr., M.D., a Board Certified Plastic Surgeon, discusses the phenomenon of capsular contracture and the factors that contribute to its occurrence. http://www.drvitenas.com/breast-augmentation.html Many studies have been conducted stating that capsular contracture rates varies between 10% and 50%. From what we know today, the most meaningful way to try to explain these discrepancies in the body, specially the breast area, is to consider that the risk of a severe capsular contracture occurrence might be close to 10% and the risk of getting mild capsular contracture is close up to 50%. Implant surface, implant type, implant position, and site of incision may affect your risk of capsular contracture. In all cases, saline implants are placed under the muscle through an infra mammary incision, which has the lowest rate of capsular contracture. In addition, textured silicone breast augmentation implants are placed over the muscle beneath the breast tissue through an aureola incision having the best rate of capsular contracture. Over time, doctors in their efforts to prevent capsular contracture, they have developed meticulous sterile techniques while performing surgery and implant displacement exercises following post-surgery. Recommended by all plastic surgeons, displacement exercises are thought to stretch surrounding scar tissue inside the breast, therefore reducing the rate of a patient developing capsular contracture.
