Implant Delivery Technique for Prepectoral Reconstruction after Endoscopic-assisted Nipple-sparing Mastectomy

Prepectoral breast reconstruction through a small axillary incision during endoscopic-assisted nipple-sparing mastectomy or robotic nipple-sparing mastectomy is difficult. Cases involving implants covered with an acellular dermal matrix (ADM) are particularly difficult. Therefore, a new delivery technique for ADM-covered implants is needed. The ADM pocket for complete coverage of the implant is made with double-crossed ADMs. The pocket end is open and sutured at the funnel entry. After insetting the ADM pocket at the mastectomy site through an axillary incision, the implant is delivered from a funnel to the ADM pocket by squeezing. Prepectoral breast reconstruction with the new delivery technique for implants covered with ADM pockets proved easy and safe. Our new implant delivery technique could be a good option for prepectoral breast reconstruction after minimal breast surgery.
