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.
联体双胎腹部联体分离后的腹壁重建对重建外科医生来说是一项挑战，因为分离往往会导致涉及皮肤和腹壁的大缺损。我们描述了一种多组件医学模型的制作，该模型旨在模拟各种软组织元素并增强术前规划能力。制作了一个真人大小的联体双胎模型，包括下胸部和腹部的圆周呈现。该模型由模拟软组织密度的泡沫芯和硅橡胶皮肤组成。将处于不同扩张阶段的组织扩张器雕刻在模型上，以确定所需额外皮肤的量。在长达20小时的手术中使用了在模型上精心设计的重建方案，手术使这对双胞胎成功分离。我们相信，创建定制的多组件医学模型可增强复杂重建手术的术前规划能力。
