Hi, TBDProblem. Congratulations on your upcoming surgery! Over or Under the muscle with a tuberous breast is a very difficult question! Generally, the dogma has been that a tuberous breast is addressed with putting an implant over the muscle, releasing the constrictions, and performing a "donut" mastopexy. This approach provides the best opportunity to most thoroughly release the constrictions inherent in the tuberous breasts, to allow the implant to most thoroughly reshape and fill the gland, as well as to best reposition the protuberant, coned distal breast tissue over the implant and to cause some central flattening in order to reduce the excess coning that occurs with the tuberous breast. Also, wide cleavage is also usually an issue with a tuberous breast, and implant placement above the muscle will slightly improve this issue, while placement under the muscle will aggravate it. However, there is a higher risk of capsular contracture and/or hardening of the breast, the implant may be more visible and have more sharp border, the upper pole of the breast may not be as attractive, mammograms may be more difficult to perform, and the circulation to the nipple and breast tissue undergoes more disruption (that may be an issue with future surgeries). In my area, many of my patients have tuberous breasts or a more mild variant, and I perform both techniques depending on their specific expectations and breast exam. Your PS will be in the best position, based on his/her experience and training and your in-person evaluation, to make a good recommendation. Best of luck to you, and I hope you achieve great results and have an uneventful recovery!
