I have had silicone implants under the muscle for 4 years, no major problems except slightly palpable, and I can feel a small knuckle near my cleavage. My surgeon suggested an implant removal surgery under local anesthesia, and leaving the capsules behind. How would you be able to tell if the capsules are thin and soft before surgery? What happens during the surgery if you find out then the implants were leaking? The local asnesthesia wouldn't be enough if the capsules need to be removed.
