Capsular contracture is a frustrating part of breast surgery that can occur in a small percentage of patients. The reasons for capsular contracture can vary. However, a few major themes are present and often capsular contracture can be due to multiple factors. A common feature seen is capsular contracture is the presence of a biofilm which is a small amount of bacteria that can collect on the surface of the implant. The body tries to clear the bacteria; however, it is unable to clear it due to the presence of a foreign body (the breast implant). The result is an inflammatory reaction that occurs which causes the body to tighten and potentially thicken the scar tissue around the implant tightening the breast and creating a hardened appearance or a firmer feel to the implant. A solution to this is generally to remove the biofilm, which entails removing the implant and replacing it with a new implant and removing the old capsule and washing the pocket out with antibiotic washes.I also frequently use an acellular dermal matrix called Strattice, which can help to reduce the risk of recurrent capsular contracture. One of the causes of capsular contracture can include trauma to the breasts particularly when there is the presence of blood in the breast pocket, which can also trigger more inflammation of the body. Size of implants does not have a major impact on capsular contracture rates. Some studies have shown that larger implants are actually somewhat lower risk for capsular contracture. However, I do not feel that implant size should be taken as a significant consideration when dealing with capsular contracture. Breast implant size should be appropriate to the base of the patient’s body dimensions. One major factor specific to capsular contracture is location of the implant placement. If the implant is placed above the muscle, the patient could be at higher risk for capsular contracture whereas if the implant is placed under the pectoralis major muscle the risk is lower. Likewise, textured implants can reduce the risk of capsular contracture particularly when the implant is in the subglandular (over the muscle) position. If you have had an issue with prior capsular contractures and are seeking treatment of this, I would make sure that you are working with an experienced Board Certified Plastic Surgeon and you should consider complete capsulectomy, implant exchange and possibly the use of an acellular dermal matrix to lower your risk of problems in the future. Best of luck!
