Breast reconstruction is a surgical procedure that restores the shape and form of the breast after a mastectomy or a lumpectomy. Breast reconstruction is frequently done at the time of the mastectomy for best results. Ultimately, a silicone or saline implant is placed in the breast to maintain the shape of the breast. Breast Reconstruction usually requires two operations (stages) but occasionally can be done in one stage.  A tissue expander is frequently placed at the time of the mastectomy and later changed to an implant. A few appointments are frequently needed over the first 6 weeks after the initial operation. Recovery time is typically between 4-6 weeks.

Pre-Pectoral Breast Reconstruction: 

This is a surgical technique that eliminates dissection of the pectoralis major muscle by placing the implant directly under the skin on top of the chest muscle, without the need to cut or lift the muscle. The over-the-muscle method can help alleviate the pain associated with muscle stretching.

Pre-Pectoral breast reconstruction is a technique used during a reconstruction revision surgery as well. If you've had breast reconstruction in the past, a revision surgery may be necessary for a few reasons, including animation deformity and pain.
Sometimes when breast implants are placed under the chest muscle (Sub-pec), the muscle may be pulling on the overlying tissue during activity and cause unwanted or unnatural movements. This is called animation deformity. If this is the case, change to pre-pectoral reconstruction is indicated to address the animation deformity and the pain.
