Debating on 650cc's mod plus or 750cc'ss high profile. 5'1, 113 lbs. Is 750cc HP totally out of proportion with my body?

Whether you decide to go with moderate plus or high-profile depends on your examination. The volume is a bit more subjective. If you have a very narrow chest and desire significant volume in the high-profile implant is a better selection.

Dear Marcy,Please, please re-consider! Large implants in a petite frame like yours are unstable and can cause a number of complications.Pain, ptosis, displacement, etc. Just to name the obvious. Bigger is not always better.Best wishes,Gary Horndeski M.D.

HI,Based on your size and weight, I believe that 750 cc is much too large for you. I also think that 650 cc is too large. You may be happy immediately after surgery, but you will stretch the tissue over time and be left with very large and sagging implants. I strongly recommend going smaller than the sizes that you mention.Regards,Daniel A. Medalie, MD

The size of implant you have selected does seem to be too large for your height and weight.  You probably don't want your breasts to enter the room before you do!  I'm curious as to what size recommendation your surgeon made?  Best wishes.

Thank you for the question.  Ultimately, careful communication of your goals (in my practice I prefer the use of goal pictures and direct examination/communication in front of a full-length mirror) 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. I have found that the use of words such as  “natural” or "C or D cup” or “porn star” or  “out of proportion” 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.
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).
I hope this, and the attached link (dedicated to revisionary breast surgery concerns), helps.

you have a relative petite frame and I would guess that 650cc- 750cc implants are going to look huge - forget the shape of implant issue. Have you actually had sizing done to show you what these might look like? Also keep in mind that large implants in a patient so small will undoubtably cause significant stretching over time. I bet you will be back in the future to have smaller implants

I think that such large implants on such a small frame might not be the best choice and lead to problems. Best to be evaluated in person to see if your anatomy can "handle" that size.

The answer to your question is that "yes"- you are picking big implants for your frame or size. But it doesn't mean that you shouldn't pick them or they are wrong for you.It's the plastic surgeons job to help you pick "your" size. Bigger implants will be faker looking and with greater chances of seeing and feeling the implant edges. However, if you pick too small you won't be happy with the size.The implants you have selected both have diameters wider than your width. This does not mean they can't be used.Check out the video on my web page on "choosing size."  Also, review the educational writing on my page called "Do your homework."These will help you with your decision. I'm not sure what size saline implants you have in now. This can be a factor in your decision. You might not be happy with the 650 cc implant. I think that you may be more unhappy about not going big enough than having a little more fake-ness with the bigger breast implants. The 750 cc implants will probably make you happier.I hope this helps. Go to the pages I recommended by linking below.Hope this helps!Dr Chris Saunders 

650 cc for your measurements is an aggressive recommendation. It is unlikely that 750 cc HP would make sense both from the size and the projection for your body profile. Consult in person with 3 board certified plastic surgeons to understand your options, and choose the one that best fits your needs and objectives.
