Closure of defects after trauma or excision of neoplasms is a basic skill in plastic surgery. Local, regional and distant flaps lead to additional scars. Skin recruitment by serial excision or skin expansion is a less damaging option for defects that must be closed. Advantages of tissue expansion include good colour and texture match. Disadvantages are the need for a second operation, use of an implant with the attendant risk of infection, time needed for inflation of the device, repeat visits to the clinic, and punctures to inflate the expander. To overcome the last disadvantage, an osmotic expander was developed in Germany in 1999 by OSMED GmbH (Ilmenau).
创伤后或肿瘤切除后的缺损闭合是整形外科的一项基本技能。局部、区域和远位皮瓣会导致额外的瘢痕。对于必须闭合的缺损，通过连续切除或皮肤扩张进行皮肤募集是一种损伤较小的选择。组织扩张的优点包括颜色和质地匹配良好。缺点是需要二次手术、使用植入物伴随感染风险、装置充气所需时间、需要多次到诊所复诊以及为扩张器充气的穿刺操作。为克服最后一个缺点，1999年德国的OSMED GmbH（伊尔默瑙）研发了一种渗透扩张器。
