SUBPECTORAL placement has several advantages over subglandular placement. This placement provides greater cushioning between the implant and the skin for slender women with petite breasts. It has a reduced incidence of capsular contraction and interferes less with mammography. There is a lower rate of rippling, and a reduced chance of downward displacement of your implants. But placing the implant under the muscle results in greater postoperative pain and a longer recovery period, with more swelling that may last for weeks or even months.
Above or below the muscle?
The most common placement for implants is Submuscular, or Subpectoral, under the pectoralis muscle.
Implants can also be placed above the pectoralis muscle and below the breast tissue or gland. This is called Subglandular.
Submuscular augmentation usually requires a general anesthetic, whereas the subglandular approach can often be performed with some intravenous sedation and local anesthetic.
