Breast implants can be placed either partially under the pectoralis muscle (submuscular) or over the muscle and under the breast tissue (subglandular). The goal is to provide optimal long-term coverage of your implants and to avoid creating deformities which cannot be corrected, including visible implant edges and rippling. For correction of the tuberous breast, Dr. Naidu generally prefers placement under the muscle. Clinical studies have repeatedly shown a decreased incidence of capsular contracture (tight scar tissue surrounding an implant) following implantation below the pectoralis muscle as opposed to above.
