Should I go with 375 or 400cc silicone moderate implants? (Photo)

I think you'll be happy switching from saline to silicone implants.  What size to go with is a very important consideration.  For patients that want to see a noticeable difference in size from their existing implants, I usually recommend increasing the volume by at least 100cc.  I will typically utilize the existing scar from the original surgery to replace implants- whether it is infra-mammary fold, peri-areolar or trans-axillary.  This way you will not end up with new scars.  Your surgeon should perform a thorough analysis of your body measurements to help in choosing the proper size and profile of implant that will give you the optimal results.  If you are still unsure about their recommendations, ask your surgeon to explain their rationale.  They should be happy to provide this information.  If not, get another opinion from a board certified plastic surgeon.  Best of luck!

Thank you for the question and pictures. You will find that online consultants will not be able to provide you with specific advice in regards to selection of specific breast implant size/profile. Ultimately, careful communication of your goals will be critical.
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. For example, I have found that the use of words such as “natural” or "C or D cup” or "fuller but not superfake" etc means different things to different people and therefore prove unhelpful.
Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup size may also be inaccurate.
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 ( after the use of temporary intraoperative sizers). Viewing the patient's chest wall in the upright and supine positions, with temporary sizes in place, help select the best breast implant size/profile for the specific patient.
I hope this, and the attached link (dedicated to revisionary breast augmentation surgery concerns), helps. Best wishes.

Thank you for your question.  Firstly, when doing a procedure with remove and replace, often times the original incision site will be utilized for the procedure.  With regards to size selection, there is very little difference between the 375cc and 400cc implant.  Select the size implant that you and your doctor believe will best achieve your overall desired result.  Perhaps consider trying on sizer implants to ease your mind and answer your question.Best regards,Dr. Lane F.
