Where will my breast implants go? January 25, 2023 Dr. Downey or Dr. Bullocks may use any of the placements for your breast implants: Submuscular. In submuscular placement, the breast implant is placed beneath the pectoral muscle. This allows more “coverage” over the implant and protects it from visibility and palpability. It also decreases the risk of rippling and capsular contracture. Submuscular placement is ideal for thin women with very little breast tissue. Subglandular. During sub-glandular placement, the breast implant is positioned over the pectoral muscle but under the breast tissue. This technique is ideal for patients who have enough tissue to “cover” the implant and for women with some degree of sagginess. Subglandular placement prevents a double bubble, which occurs when the implant causes the appearance of a breast on top of a breast. Dual Plane. This technique involves the top half of the breast implant being covered by the muscle and the bottom half of the breast implant being covered by the breast tissue. Dual plane placement helps to reduce the visibility of the breast implant in thin patients who also have a little sagging and may be prone to “double bubble.”
