Complications after breast lifts are relatively rare. The main three are bleeding, infection, and scarring. Your surgeon will give you instructions for preparing that will help lower your risk of complications. Those instructions will include such things as not smoking, making sure you are off medications that may make bleeding more likely, and taking antibiotics if necessary.
There are cases where some patients are wanting a very unnatural or obviously augmented look. This can be created by placing the implant over the muscle, as it allows you to really define the sharp edges of the implant, which in turn will create a very obviously implanted look. Aside from that, the advantages of going over the muscle can come in terms of the fact that you are preserving the strength of the pectoralis muscle. Some patients who are athletes or weight lifters, may want to ensure that they are maintaining 100% of their power and strength, therefore if the breast implant is placed over the muscle it allows them to maintain their ability to bench press at their highest weight. Furthermore, there are some patients which due to their anatomy, it is required to place the implant over the muscle. For example, if they had a previous breast augmentation where the breast implants was placed under the muscle that left significant scarring or if they had a severe capsular contraction, it would be recommended that they switch the location of the implant. Another benefit to having the breast implant placed about the muscle is that it can offer a more defined round shape if the patient’s breast has tissue that takes on a different shape.
MENTOR® MemoryGel® Breast Implants, MENTOR® MemoryShape® Breast Implants, and MENTOR® Saline-filled Breast Implants are indicated for breast augmentation in women (at least 22 years old for MemoryGel® Implants and MemoryShape® Implants, and 18 years old for Saline Implants) or for breast reconstruction. Breast implant surgery should not be performed in women with active infection anywhere in their body, with existing cancer or pre-cancer of their breast who have not received adequate treatment for those conditions, or who are currently pregnant or nursing.
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.
