What does the dimpling of a breast implant for reconstruction mean?

Nature of implant: Following mastectomy the remaining tissues become thin and provide insufficient soft tissue coverage over the implant even if placed under the muscle. Most implants have a tendency to fold/wrinkle and certain positions may make the wrinkling worse (saline>silicone). Capsular contracture may also increase rippling/rupture. The new "gummy bear implant may decrease this tendency. Use of adms may also.

Consider a rupture: It's possible that your saline implant broke. I would recommend you see a plastic surgeon. Please bring any information regarding your implants to this surgeon, including any cards you may have or a copy of the operative report if they didn't do the operation. Should be an easy fix. It is also possible that you have simply developed rippling. You may need to switch to gels if this bothers you.

Varies.: “rippling” or palpability of breast implants is not unusual after breast reconstruction surgery. This is especially true given that there is no longer as breast tissue coverage of the breast implants. If this rippling/palpability increases, it may be a sign of breast implant leakage. Sometimes, the use of silicone gel breast implants and/or acellular dermal matrix may be helpful.

Rippling?: Not sure what dimpling is... Rippling is when you can see ridges in the implant through the skin. The less breast tissue you have overlying the implant, the more likely you are to have rippling. It is more common with saline implants and more common with implants placed above the muscle (cosmetic use).
