Post-operative patient surveys about mental health and quality-of-life, reported improved physical health, physical appearance, social life, self-confidence, self-esteem, and satisfactory sexual functioning. Furthermore, the women reported long-term satisfaction with their breast implant outcomes; some despite having suffered medical complications that required surgical revision, either corrective or aesthetic. Likewise, in Denmark, 8 per cent of breast augmentation patients had a pre-operative history of psychiatric hospitalization.
In 1998, the U.S. FDA approved adjunct study protocols for silicone-gel filled implants only for breast reconstruction patients and for revision-surgery patients; and also approved the Dow Corning Corporation's Investigational Device Exemption (IDE) study for silicone-gel breast implants for a limited number of breast augmentation-, reconstruction-, and revision-surgery patients.
Since experienced surgeons are aware of these issues with saline breast implants and their need for eventual replacement, they opt to place them under the chest muscle. The chest muscle works as an extra layer of tissue over the implant, which makes for a smoother transition from the chest wall to the implant. The finished product is a more seamless transition versus a more visible and abrupt change when the implant is not placed below the pectoral muscle. As for gel breast implants, they can also be safely placed below the pretorial muscle if that is a viable option for the patient since replacement and wrinkling is less common with this type of implant.
