The use of acellular dermal matrix (ADM) for bilateral breast reconstruction has increased in recent years. Detection of BCRA mutation and therefore bilateral risk-reduction mastectomy is one of the main reasons for this increase. High cost of ADM is considered a major drawback for its use. The authors present a new technique which allows the use of only one unit of ADM for both breasts. After assessing the viability of the skin of mastectomy flaps, a musculofascial pocket formed superiorly by pectoralis major, laterally by serratus fascia and inferiorly by rectus fascia, is performed. Then, the ADM is divided in two halves. We propose two different ways to divide the matrix, cutting it vertically or diagonally in two. The way in which the matrix should be cut depends on the distensibility of the pocket. Afterwards, the implant is inserted and the exposed area of the implant is covered by the ADM sutured to the edges of the musculofascial pocket. Using only one ADM unit for bilateral reconstruction, the procedure becomes not only more cost-effective but also can reduce complications such as seroma, rippling, wrinkling, and visibility by means of a better coverage with lesser foreign body load. Furthermore, the lesser the matrix used, the faster the integration is achieved.
