When the rib cage, shoulders and pectoral muscles are unbalanced the placement of the implants or reduction can be adversely effected. The only way a surgeon can judge is by a visual assessment of how to place and position the implants or reduce the breast tissue on the chest. The top of the torso needs to be balanced at the time of surgery.
The markings on and around the breast and surrounding skin is usually done with the patient sitting upwards. However, if the muscles are not aligned then the breasts may be uneven after surgery.
Having myofascial release on the shoulders, rib cage and chest will allow the alignment of both sides to be the same, giving a better outcome for the patient.
