Do high profile implants (300-340cc round, smooth) look fake on a small frame?

With the new implants having much firmer gels I really try to not use the high or ultra high profiles especially when patients dont want a "done look" because they hold their shape so well 

It's really impossible to tell without measurments and an exam. Off hand I think that the HP implants you have mentioned probably would do fine. What I am not familiar with, is the brand of implant. The only brands I am aware of as being approved for use in the US are those made by Allergan, Mentor and Sientra. 

In our practice we use Allergan Natrelle -- exclusively. I believe that Nagor Implants-- are not FDA approved and I would not use them. We spend great amount of time sizing the patient and embracing your input in determining the final size. High profile implants are best used for petite , narrow framed women. The difference being the base diameter being narrower so that the breast projection can be maximum. Without photos -- it is impossible to tell what you would be a candidate for.

Thank you for the question. In regards to specific size/profile of breast implant, despite good intentions, online consultants will not be able to provide you  with  meaningful specific advice.  Ultimately, in person consultation with well experienced board-certified plastic surgeons will be necessary. Careful measurements, dimensional planning, and careful communication will be key.
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.  Again, have a full discussion and communication regarding your desired goals with your plastic surgeon. This communication will be critical in determining which operation and/or 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 "look fake" 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.  The use of computer imaging may 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.  The use of temporary intraoperative sizers, viewing the patient's breasts in the upright and supine position, are very helpful during the breast implant selection process.
I hope this, and the attached link (dedicated to petite patients), helps.

Most likely these are Mentor implants.  A HP implant will tend to make the breast look rounder.  In the range you are using you should be fine.  

I agree with you and how you are thinking things. Best to seek a few IN PERSON opinions from boarded PSs in your area... 

I have never heard of Nagor implants.   Only Allergen, Mentor, and Sientra are approved in the US.   You want  implants with a warranty.   High profile  implants simply have a LITTLE more projection and a LITTLE  narrower base.    You will be fine with high profile.   My Best,  Dr C

High profile implants are most commonly used on petite women with a very small frame and narrow chest.  It sounds as though your plastic surgeon has measured you and has made an appropriate decision for you.  I agree with others that you are better off having Mentor, Allergan, or Sientra breast implants that are FDA approved.  I would be very concerned why your plastic surgeon has chosen that type of implant.
