What exactly does muscle dissection mean?

Hello, thank you for your question. Usually for sub muscular placement we make a small opening into the base of the pectoralis major to insert the implant. Yes we dissect under the muscle to separate it and make room for the implant (not tear it up).What you are describing in your question most likely took place in a implant removal NOT and implant insertion. In the case of an implant removal and a capsulectomy where we attempt to remove the capsule, sometimes some of the muscle is so tightly adhered to the capsule that some of it may also get removed. However even if in this case the remaining preserved muscle heals down and patients are still able to use their pectoralis major and minor normally. The pec minor is not affected in these scenarios. Check out our website for more on capsulectomies.

Most of the muscle is just lifted up so that the implant can slide in under. However, close to the lowest area near the breast bone, muscle is often released for a short distance and cauterized to minimize bleeding. Otherwise, there may be an awkward flexing and lifting of the implant when the muscle is used.

Dear ErikaApril08,
in order to place implants under the muscle, your surgeon will need to cut a small part of the muscle from the chest wall. I almost always place implants submuscular. It lowers the rate of capsular contracture significantly. In addition, it looks much more natural because the muscle provides covering over the implant so its not as round on the top. I've also noticed the implants drop less over time when they are protected under the muscle.
