目的:讨论腹部皮肤软组织扩张的规律和效果.方法:选取2009年2月至201 0年6月入院接受腹部扩张器置入术的3例患者,埋置腹部扩张器5枚,定期注水扩张.于注水末期行腹部CT扫描.将CT扫描结果导入Mimics 10.01软件,测量模拟原腹部轮廓至扩张器内、外界的距离并比较二者大小.结果:在注水末期,2枚扩张器向外扩张距离明显大于向内扩张,1枚向内扩张距离明显大于向外扩张,2枚向内、外扩张的距离相近.结论:腹部皮肤软组织扩张术仍是获得"额外"皮肤的有效手段,但对扩张过程中皮肤增加规律尚需进一步研究明确,以利于提高扩张效率、预防潜在并发症.%Objective To discuss the pattern and result of abdominal skin and soft tissue expansion. Methods From February 2009 to June 2010,3 patients underwent abdominal skin expander implantation with together 5 expanders. The expanders were inflated regularly. At the end of the inflation, CT scan was used to analyze the expansion by mimics 10.01 software. Simulate the skin border on the axial view of the CT image,then calculate and compare the distant of internal compression and external expansion. Results At the end of the expansion,2 expanders expanded more than compressed, one expander expanded less than compressed and 2 expanders expanded closely to compressed.Conclusion Abdominal expansion is still an effective method of harvesting extra skin. But more research should be done to make clear the pattern of expansion in order to improve the efficiency and prevent potential complications.
