If I want this kind of look should I get tear drop implants? Also what percentage risk do they have of flipping/moving? (photo)

Thank you for the question. 
These days there are a variety of breast implants available; the variety of breast implant available raise a lot of questions from women considering breast augmentation surgery. Personally, I think that for most patients considering breast augmentation surgery, careful selection of plastic surgeon and careful communication of goals, far outweigh the specific type of breast implant utilized (when it comes to the success of the breast augmentation procedure).
Anatomical breast implants were designed to better simulate the natural breast shape; the problem with these implants is that if they shift or rotate, the entire breast will change shape as well. This change in breast shape may require further surgery to correct. Round implants, under the hand, can shift or rotate without changing the shape of the breasts. Overall, I find that beautiful outcomes can be achieved with the use of round saline or silicone gel breast implants for the vast majority of patients.
Generally speaking, the best online advice I can give to ladies who are considering breast augmentation or 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 “very 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. Again, the use of computer imaging has been very helpful during the communication process, in our practice.
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 helps. Best wishes for an outcome that you will be very pleased with. 

Hello Eleanor,This is a difficult question to answer and would be best addressed with an in-person consultation.Teardrop implants do run the risk of rotation and so this risk needs to balanced against the benefit in terms of the difference in shape with less fullness in the upper part of the breast.  You could consider polyurethane foam implants which are much less likely to rotate than textured silicone implants.I would be concerned about going bigger and going teardrop.  For a given base width, a teardrop implant will tend to be smaller than a round implant.  This means that if you are going for a 400cc teardrop implant, it is likely to be quite a bit wider than your 265cc round implants.I would always advise caution about going too wide with your implants as this can cause problems (synmastia, lateral fullness).  This is why I really think you need to go over everything with a fully trained plastic surgeon - look for the letters FRCS(Plast) after their name.Good luck.
