Can you repair pectoralis muscle after explant? 2 months post op.

The dual-plane procedure is associated with animation deformity to some degree in many patients, because of detachment of the pectoralis muscle. If it is not re-attached when implants are removed, the distortion can persist. It is repaired by suturing it to the posterior capsule. I do this frequently, most often leaving the implant in but converting to the split muscle plane with muscle re-attachment. There are several articles and videos on my site.

It is possible (and with difficulty) only after the wound has been created there and then, for instance in time of immediate breast reconstruction. Following implant placed under the muscle it is not possible.

Following removal of sub-pectoral breast implants, the pectoralis major muscle can be restored to its prior anatomic position. The reconstruction of the muscle may improve its function and might in some instances diminish abnormal-appearing contractions which can persist after implant removal. 
I reconstruct and reposition the muscle with the patient under general anesthesia, and utilizing muscle relaxation in the anesthesia. I mobilize the muscle from the overlying breast tissue, advance the dis-inserted border towards the the breastbone(sternum), and meticulously suture it into place with strong suture material. The muscle and any remaining breast capsular tissue is fixed to the periosteum of the sternum and rib cartilage in that area.
The patient has to carefully follow instructions after surgery to allow the muscle to heal in it’s restored position.

If your muscle was released, it may be a difficult and painful repair. The muscle would need to be sutured to the sternum (bone). This could be done with large needles but would require general anesthesia; it would be too painful using local anesthesia. I never release the pectoralis major muscle from the bone in any patient because it is a difficult repair and I see problems without any benefit. Having the capsules in place may help the surgeon to place the sutures.
