Using two different (silicone) implant sizes for slightly different boobs?

If it is not noticeable now and does not bother you, then using the same size will probably be the same, trust your surgeon's advice. Good luck.

Thanks for your inquiry, and this is a common situation.  In general terms, most implants come in sizes 20-30 cc apart in implants under 500 cc, over 500 cc the implants come sometimes in 40 plus cc increments.  If the difference between you breast is closer to a size difference in the implants then pick different implants, hope that helps and best of luck.  

In general terms, using the same implants will leave you with the same difference that you currently have.   You will pay more attention to the breasts afterwards and small differences that were previously not recognized can become more noticeable with closer attention.   If the difference is currently not noticeable there isn't much indication to use asymmetric implants.  You have chosen your surgeon for a reason.   I would rely on his or her expertise to determine if you would be better off with different implants or not.  

Thank you for the question.  I find that I use different sizes of breast implants for an individual patient undergoing breast augmentation surgery quite frequently.  Sometimes, when there is significant chest wall asymmetry as well, different profiles of breast implants may also be helpful. Of course, if there is very minor breast degree of asymmetry, use of different sizes of breast implants is not indicated.  My patients will also hear me say: "sisters not twins", despite best efforts.My best advice: more communication.
It is definitely worth spending more time (prior to the date of surgery) with your plastic surgeon to discuss further.  As you know, it will be important for many reasons, that you feel comfortable that you and your plastic surgeon are on the "same page" prior to proceeding.  This additional communication will go a  long way when it comes to helping alleviate your anxiety prior to proceeding.
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” 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.

If you appreciated a difference or its at least a 1/2 cup size different, its certainly advantageous to go with different sized implants.  Achieving perfect symmetry is not guaranteed and it will only make you closer to equal.  On the other hand, if the difference is small, it should not be appreciated if same sized implants are used and the analogy I use is compare a golf ball and a ping pong ball and the golf ball is obviously larger.  Add a softball to each and hold them side by side and now tell me quickly which one is larger... much harder to tell now.  Trust your surgeon as he/she doesn't want you to be unhappy since you are a potential source of future referrals and he/she should be doing their absolute best for you.

Implant selection is very important in breast augmentation. Implants that fit your body and provide the necessary size increase will look and feel the best. When it comes to asymmetry, it is important to assess just how much difference there is between your breasts. If the difference is subtle, many surgeons will recommend using the same implants on both sides. If the difference in size and shape is obvious, a larger implant on one side can be beneficial. Breasts are never identical, but we want them to be close in size and shape. Always see an American Board of Plastic Surgery/ASAPS member surgeon.

Hello. Thank you for your inquiry.

It is important to have an in-person assessment regarding your concerns as it is difficult to determine virtually without any photos. If the difference is very minor, your surgeon may recommend to leave it as is.

There are many different factors that go into choosing a breast implant size which will correspond with your body dimensions while concurrently achieving your aesthetic results. Some of these factors are: Implant size (CC's), Implant profile (Low, Moderate, High), Placement of the implant (Subglandular vs. Dual Plane) etc. We utilize smooth round cohesive silicone gel 'gummy bear' implants for the best results.

During a consultation your aesthetic goals are heard and taken into account with the measurements of your breasts and the integrity of your tissue, as well as level of ptosis (sag). From here we collectively can find your 'perfect fit'.
You are able to try out sizers and different implants in our office such that you can get an idea of what size you would be post-operation. We also offer Crisalix 3D plastic surgery virtual simulator during our in-person and virtual consultations to preview potential results. After your consultation, you will receive your very own implant sizers to take home with you (at a small cost) whether or not you decide to go forward with your procedure.

I usually recommend that my patients stop smoking, take vitamin C daily, and avoid aspirin/ibuprofen and vitamin E 3 weeks prior to surgery.
