Can you limit the muscle disruption when replacing implants under muscle?

This is a tough question without some additional background and pictures, to know what the original breast size, implant size, and current status is. In general, if you are looking to remain about the same size and already have a pocket under the muscle, likely no additional muscle needs to be released at all. If you are looking to upsize, depending on the shape currently and where the implant needs to be positioned, i would typically transition to a dual plane technique that would also avoid any additional muscle division. Hope this helps.

Since the space has already been made, the muscles will not be cut to replace the implants. I do suggest not going larger for you might notice more muscle flexion. You still will have to give yourself time to heal before going back to Cross Fit.

Dear Anonymous4545452,
if your muscles are placed under the muscle, it is most likely that your surgeon won't need to further release pectoralis muscle. If you are considering surgery, I would suggest you consult a board-certified plastic surgeon. Only after a thorough examination, you will get more information and recommendations.
