Sub-glandular Breast Implant Placement (also known as “Overs”): The breast implants are placed below the breast gland but above the muscle. The term ‘over’ derives from the placement of the breast implant over the muscle.
Partial Sub-muscular Placement (Also Known as Dual Plan Placement): This placement has many names, but essentially the implant is placed partially below the muscle. This can also be referred to as partial submuscular, partial subpectoral, and, although it’s not really correct, submuscular and subpectoral. Sometimes people even refer to this placement as ‘unders’, but that term should really be used for complete submuscular placement.
Complete Sub-muscular Breast Implant Placement (also known as “Unders”): Here the breast implant is placed completely below the muscle. This is correctly referred to as submuscular or subpectoral.
Sub-facial Breast Implant Placement: There is a thin layer of tissue called the fascia covering the muscles of the chest. Some surgeons will separate the fascia from the muscle and place the breast implant under the fascia. Sub-fascial placement is offered by few plastic surgeons.
Advantages and Disadvantages: see this section for a synopsis of the advantages and disadvantages of each breast implant placement, but be sure to read the links above on each one first!
