Which would you recommend; 280cc Moderate or 300cc High Profile?

Dimensional planning may be performed by your surgeon, based on a variety of measurements such as breast width, your height, weight and etc. This would give you a better idea of which would be more suitable for you.

Hi. I hear your dilemma. You failed to post photos and therefore an accurate assessment of your breast a cannot be made. You've chosen your surgeon for a reason. I am assuming you personally met with him/her and spent time discussing your options. Did you try on sizers? Mentor makes a great sizing kit that I use on everyone. Whether or not your breasts will look fake, depends. Did you look at countless photographs of previous patients your surgeon has done? Do they look fake? I assume that all,of this was done and that he/she was able to gain your trust. If so, then go with the suggestions. There is no substitute for research. If you have already committed to your surgeon then discuss your concerns with him/ her. Looking natural after a breast augmentation is always my primary goal.

The most important suggestion I can give you is to find a board certified plastic surgeon who will guide you through this process. Computer software morphing programs that automatically determine the best implant size can be helpful in some but not all cases (e.g. doesn’t work well in my experience with existing implants, sagging or asymmetric breasts).It is very difficult to determine the exact size and shape implant you will require to best match your ideal breast image without an examination by a board certified plastic surgeon. Not just any board certified plastic surgeon, but one with many years of frequently performing breast augmentation surgery including different approaches, techniques and implant choices. This is because several measurements not to mention your breast characteristics are needed to determine the optimal implant size to obtain your goals. Without knowing these dimensions it would be difficult to make this determination. For example, the existing base width of your breast will determine, in many cases, the maximal volume per implant profile that you can accommodate. To illustrate; a 100 cc difference may make a significant difference with a narrow base width breast, but much less of a difference if you have a wide chest wall and wide breast “foot print”. Therefore, just because your friend may have a great result with let’s say a 350 cc implant to make her go from a “A” cup to a “C” cup size does not mean that you will have the same result with the same size implant. . Further simply placing implants in a bra to determine the size best for you is not always accurate as the bra often distorts the size, is dependent on the pressure the bra places plus the implant is outside your breast and not under it among other variables. Using “want to be” photos however are useful if simply provided to the surgeon as I will further explain in the below link.

It sounds like you have narrowed down your choices to two implants with a fairly close volume.  Ultimately the final decision will be yours to make, based on trying on sizers, looking at before and afters, and/or looking at 3D imaging of the breasts.  Perhaps one final appointment will help you make the decision.

At our clinic our philosophy is all about achieving the most natural looking results. To choose a projection that's going to give you the most natural looking result, it really depends on the width of your breast. A low projecting implant is wider while a high projecting implant is much more narrow. So for example if you have a wider breast shape, an implant with a lower projection is going to give you a more proportional appearance. If you have a narrower breast shape to begin with, the higher projecting implant will probably give you a better result. Both will give you a boost in volume but the main difference is the shape they create relative to your pre-existing breast shape. The best thing to do would be to discuss the look you want to achieve with your surgeon, make sure you've been measured carefully, and discuss these details with them carefully so that you feel confident that the implant you choose can achieve your goals.

If the moderate implants did not project enough then you need to use high profile or go larger moderate  profile. In my practice 280/300 are relatively small implants and if you are concerned they might be too small you need to revisit your PS and try on additional implants. For your size try 360/ 390 or around there and you might be happier in the long run. I really feel for my patients that select the smaller280-300cc implants and come back the next day wishing they had gone larger.

Firstly silicone implants are only approved for woman over 22 in the US, in general I urge patients to go with a moderate projection to maximize the natural result

Thank you for your question.    I would recommend sizing again with your surgeon, bringing in photos of your desired look, and even doing  the rice test to help finalize your decision.It is very difficult to accurately discuss implant volume without an exam and detailed measurements.In order to make an accurate size recommendation, I would need to assess your chest wall and breast mound measurements and characteristics. I use these measurements to help me during your sizing process to guide you to a safe result and one that meets your end desires.Your plastic surgeon will perform several measurements of your chest wall and breast anatomy and determine a range of implants that both fit your chest wall and reach your desired goals.The next step is to try on this range of implants in the office with your doctor. The key to this success is showing your surgeon the body proportion you desire with a bra sizer and allowing your surgeon to guide you to the right implant. It will be much easier to communicate in implant cc's than cup size when determining the appropriate implant for you during the sizing process. Close intereaction and involvement from your surgeon during this process can help alleviate the anxiety and fears of choosing the right size. I wish you a safe recovery and fantastic result.Dr. Gill

Very hard to decide without a posted frontal photo or an in person examination. Best to seek a few more in person opinions from the over 80+ boarded PSs in South Florida.. I prefer mod profile+ ...at 300 cc range...  

Thank you for the question. Unfortunately, online consultants will not be able to provide you with specific enough advice to be truly helpful.    Generally speaking, the best online advice I can give to ladies who are considering 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 "fake, too perky" 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 in bra sizers and computer imaging may also be very helpful during this communication phase.
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 sizers assessed with you in the upright position).
I hope this, and the attached link (dedicated to breast augmentation surgery concerns), helps.
