Preoperative planning for the separation of omphalopagus conjoined twins-the role of a multicomponent medical model.
Abdominal wall reconstruction after the separation of omphalopagus conjoined twins poses a challenge for the reconstructive surgeon as separation often results in large defects involving both the skin and the abdominal wall. We describe the fabrication of a multicomponent medical model devised to simulate the various soft tissue elements and enhance presurgical planning capabilities.A life-size model was cast of omphalopagus conjoined twins including a circumferential rendition of the lower thorax and abdomen. The model consisted of a foam core simulating the density of the soft tissue with a silicone rubber skin. Tissue expanders at different stages of enlargement were sculpted onto the model to determine the amount of additional skin required. The reconstructive design elaborated on the model was used during the 20-hour operation that resulted in the twins' successful separation.We believe the creation of a customized multicomponent medical model enhances presurgical planning capabilities for complex reconstructive endeavors.
