Objective: To evaluate the clinic application of tissue expander in treatment of extensive head and faciocervical skin defects. Methods: Sixteen patients with head and faciocervical skin defects were treated by tissue expander. Expanders of 100 ~500 ml capacities were implanted under the normal skin of head and faciocervical ar -ea nearby the defects, with built-in injection pot, subsequent expansion was carried out for 6 to 8 weeks. Expanders were taken out and the expanded flaps were transferred through rotation , advancement or axial flap to the defects in a second surgery. Results: Twenty -four defects were effectively treated , with 39 expenders, in the 16 cases. The maximum proportion repaired in single treatment was 12cm×18cm. Complications of hematoma and expender exposure were reported in 2 cases during the course of expending. Conclusion: The clinical application of tissue expander in treatment of treating extensive head and faciocervical skin defects shows great promise , though the complications should be concerned.%目的:探讨皮肤扩张器在头面部大面积皮肤病损治疗中的临床应用.方法:使用皮肤扩张器治疗16例头面颈部大面积皮肤病损患者.选用100～500 ml容量的扩张器植入病损旁的皮下,注射壶内置,注水扩张6～8周.Ⅱ期手术取出扩张器,将扩张皮瓣用滑行推进或旋转推进方式修复切除病损之创面.结果:16例患者共治疗24处病损,置入扩张器39个,一次修复最大面积为12 cm×18 cm,所有患者均得到有效治疗;扩张期发生并发症2例,为术后血肿及扩张器外露,发生率约5%.结论:应用皮肤扩张器修复头面部大面积病损是一种理想的方法,但应重视并发症的预防.
