Physical Characteristics of SurgiMend Meshed Biological ADM in Immediate Prepectoral Implant Breast Reconstruction.
MetadataShow full item record
With increasing acceptance of prepectoral implant breast reconstruction, there has been a requirement for biological acellular dermal matrices with conformational properties, high tensile strength, and rapid integration. SurgiMendPRS Meshed is a biological acellular dermal matrix derived from fetal calf with these specific characteristics for prepectoral implant breast reconstruction. The aim of this study was to test the performance of this mesh by recreating its surgical use ex-vivo using a variety of implants in an effort to define its physical properties. The mesh is usually attached with a number of interrupted sutures to the implant periphery, the variable being at the inferior border, where it can be attached as a snug fit at the level of the inframammary crease ("tent" technique) or sewn behind the implant, cradling the lower pole ("hammock" technique). The results show mesh elasticity to stretch with increasing implant weight. When used as a "hammock," greater stretch was demonstrated compared with the "tent" technique, allowing greater degrees of ptosis to be achieved. The suture points demonstrated lines of tension that progress evenly over the anterior implant surface. The mesh performed better when used at maximum stretch, but should not be forcibly stretched over an implant as the lines of stress show uneven distribution of lines of tension. These data provide a structural basis on optimum clinical use of this acellular dermal matrix in prepectoral implant breast reconstruction.
