Thank you for the question. You are correct, generally speaking, that a patient's anatomical “starting point” will play a significant "role" in the outcome that you can expect with breast augmentation surgery. Careful breast implant pocket dissection and judicious selection of breast implant size/profile will help decrease the space between the breasts as much as safely possible. On the other hand, over dissection (in the attempt to improve the "cleavage area") or the use of breast implants that are too large for the patient's dimensions, can be problematic, resulting in the need for revisionary breast surgery. Of course, your chosen plastic surgeon will be able to give you a good idea of what you can expect during the consultation process. Demonstration in front of a full-length mirror and/or viewing goal photographs will be helpful during this communication process. In my practice, I find the use of computer imaging very helpful during this communication phase. In other words, helping patients achieve a sense of realistic expectations is an important part of the preoperative process. 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. In bra sizers can be useful communication tools also. I have found that the use of words such as “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 who makes the bra; therefore, discussing desired cup size may also be inaccurate. The use of computer imaging may be very helpful during the communication process. 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 breast augmentation surgery concerns), helps. Best wishes for an outcome that you will be very pleased with.
