Will 345cc moderate profile make me look top heavy?

This is a good question and a common concern of may patients prior to surgery.  I would recommend discussing your concerns with your surgeon and perhaps going back in to be resized and look at implants again prior to surgery-- ultimately we all want our patients to feel confident with their selection of implants and be happy with their results and it may take another visit with your surgeon to make sure you are both on the same page prior to surgery.

Thank you for your question and congratulations on your upcoming surgery.  Breast implant selection is an exciting, but stressful part of the breast augmentation process as there are so many choices. Unfortunately it is impossible to recommend the best implant style, size or shape without an in-person examination that allows for the measurement of key breast parameters, as well as permits an in-depth discussion as to your desired goals and outcome. I would recommend seeing an ASPS board certified plastic surgeon, they are in the best position to ensure that the implants the two of your decide upon are the right ones to meet your expectations.  It sounds as if it may be wise for you to "try on" several of the implants so that you can have a better visual representation as to what they would look like.  Best wishes!
