A breast implant capsule is the firm, sometimes hard and thick, scar tissue that forms on the inside of the breasts and surrounds the breast implants after breast enlargement surgery. This sphere can contract over time, and squeeze the breast implants (capsular contracture). This would certainly place the breast implants in one position with almost no mobility. The positions of the left and right implants may be distorted with respect to each other, and also in relation to the chest wall. The shape of the breasts may also be made abnormal in any direction. The breasts may also feel unnaturally hard. Finally, significant pain may also be present. The incidence of this capsular contracture is thought by many plastic surgeons to be related to blood collection, fluid collection, contamination, or infection at the time of breast enlargement surgery. It is also more common when the breast implants are placed on top rather than behind the pectoralis muscle. Surgical options for the treatment of capsular contracture include releasing the capsule circumferentially, completely excising the capsule, or even the former or latter combined with breast implant replacement. Regardless of the intervention, there is no guarantee against the recurrence of capsular contracture.
