Large scalp defects pose a challenge for the surgeon. Here, we present a 31-year-old male patient with a soft tissue defect on the temple with exposed bone. To allow reconstruction, we placed a self-filling osmotic expander in the subgaleal pocket for 12 weeks. The final volume of the tissue expander was 300 mL. In the last step, a rotational flap was created after removal of the tissue expander from its pocket. Thereby, a tension-free suturing was possible. The post-surgical healing was uncomplicated. Osmotic tissue expanders are a valuable tool for the closure of large tissue defects without the necessity of repeated filling procedures.
大面积头皮缺损对外科医生来说是一项挑战。在此，我们报告一名31岁男性患者，其颞部存在软组织缺损且骨质外露。为了进行重建，我们在帽状腱膜下间隙置入了一个自膨胀式渗透扩张器，放置12周。组织扩张器的最终容积为300毫升。在最后一步，从其腔隙中取出组织扩张器后形成了一个旋转皮瓣。由此得以进行无张力缝合。术后愈合过程顺利。渗透组织扩张器是闭合大面积组织缺损的一种有价值的工具，无需重复填充操作。
