Bottoming out or capsular contracture after revision?

I am sorry you're having so much difficulty with your breast implants. This is not typical for breast augmentation. I believe the correct sequence of procedures was done, in that, during your second procedure the implants were changed to silicone and placed in a submuscular position.
Capsular contracture is not uncommon after saline breast augmentation with implants placed subglandular (above the muscle).  Compared with saline implants placed above the muscle, breast  implant capsular contracture is less when silicone implants are placed in a submuscular or under the muscle position.
Based on your pictures I would say you definitely have bottoming out of your left breast implant. To fix this you have several options;  you could either raise  the left breast implant (inframammary) fold or lower the right breast implant (inframammary) fold. Another alternative is to do a little of both.
Concerning your question regarding capsular contracture, it is difficult to say if you definitely have breast implant capsular contracture. If you have pain in the breast and firmness of the breast, you probably have a Baker Grade 2 or 3 capsular contracture.
If you were to undergo surgery I would suggest the following. If the both breast hurt,  I would therefore suggest bilateral capsulectomies for bilateral breast capsular contracture. In addition, I would go with a slightly larger implant on both sides and lower the right implant fold and slightly raise the left implant fold. I would continue with silicone implants in a submuscular position. Good luck with your surgery.

Hello! Thank you for your question! Physical examination will determine if you have capsular contracture. The look and feel of hardness surrounding your implant is seen and/or felt. At its worst, you experience pain. It may also cause distortion of your breast. What has caused it will be in question.  Given your photos and description, it may be a recurrent capsular contracture. Your surgeon will likely recommend implant massage and may add the medication Singulair. If these fail, surgical correction may be suggested. It is a matter of surgeon preference as well as what is seen during your procedure that will determine whether or not a complete capsulectomy is performed. If significant capsule formation is seen intraoperatively, a full capule removal may be warranted with a drain in order to completely remove all of the tissue and allow better adherence of your breast back to its normal anatomic position down on your chest wall. Irrigating with certain medications may also be if benefit. If minimal contracture is seen, it may be possible to leave the capsule, or place cuts within the capsule to allow better adherence. It truly is dependent on what is seen with your capsule and the issues that may be causing you to have such a procedure (e.g., contracture from rutptured implant vs pain vs simple pocket adjustment, etc). Without knowing your issues and without an examination, it is difficult to tell you what may be the best thing for you. I tend to favor performing capsulectomies in order to create a fresh pocket, reshape the pocket, allow better shape and adherence of the overlying breast. I would discuss your issues with your plastic surgeon who will assist you in determining the right modality for you. Hope that this helps! Best wishes!

Looking at photos without exam it is impossible to tell, but it appears you have a capsular contracture on the right. If so, the right implant should be tight and hard. If not then it might need revision to drop it down a little.
