The Fascia can be a delicate structure which can be difficult to raise intact. Commonly, when we perform breast reconstruction surgery after a mastectomy, the facscia is destroyed and we need to reuild it. This is one of the most commonly performed breast reconstruction technique. However, we continue to place the implant under the muscle, but reconstruct the fascia over the lower half of the breast, where it is particularly thin. In augmentation patients, the fascia also becomes this over the lower and outer portions of the breast and technically, the pectoralis fascia is discreet from the serratus fascia. The muscle is a clearly definable large anatomic structure whereas the fascia is less defined. Similar discussions are held with buttock implants due to the size fo the gluteus muscles. However, repeated pistoning of an implant with exercise or activity can thin the fascia in this location. Because the Subfascial implant placement is not widely practiced, it is difficult to draw any meaningful data from research published to date. According to my references, approximately 80% of surgeons place their implants under the muscle. Due to the tenuous nature of the fascia, I see it as a better alternative to subglandular placement, but generally believe the submuscular position offers best option. It is also important to note that is the position generally preferred by radiologists when interpreting mammograms as it results in the least distortion or obstructed visualization of the breast tissue.
