Thank you for the question and pictures. Unfortunately, online consultants will not be able to provide you with specific enough advice to be truly helpful. Keep in mind, that the issues at hand may be more than simple breast implant volume issues; adjustment of the breast implant pockets and/or revision of the previous mastopexy may be necessary to improve symmetry as well. Of course, much will depend on your physical examination and specific goals. Given your questions and concerns, you'll be best off spending additional time with your plastic surgeon communicating your goals carefully. Generally speaking, the best online advice I can give to ladies who are considering revisionary breast augmentation surgery ( regarding breast implant size/profile selection) is:1. Concentrate on choosing your plastic surgeon carefully. Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. Ask to see lots of examples of his/her work.2. Have a full discussion and communication regarding your desired goals with your plastic surgeon. This communication will be critical in determining breast implant size/type/profile will most likely help achieve your goals. In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. I have found that the use of words such as “natural” or "C or D cup” etc means different things to different people and therefore prove unhelpful. Also, as you know, cup size varies depending on him who makes the bra; therefore, discussing desired cup size may also be inaccurate. The use of computer imaging technology may also be very helpful during this communication process.3. Once you feel you have communicated your goals clearly, allow your plastic surgeon to use his/her years of experience/judgment to choose the breast implant size/profile that will best meet your goals. Again, in my practice, this decision is usually made during surgery, with the help of temporary sizers which allow for the most accurate evaluation of breast size/symmetry ( with you in the upright position).I hope this (and the attached link, devoted to revisionary breast surgery) helps.
