OBJECTIVE: To explore the application of tissue expander in ear reconstruction and to deal with the complications. METHODS: 50 ml kidney-shape tissue expanders were implanted subcutaneously in the mastoid area. The drainage tube was removed 3 days after operation. The suture was removed 10 days later. Since 7 days after operation, 5 ml NS was injected into the expander every time, three times a week. The total injection volume was about 60 ml. After that, the expander was maintained for one month. RESULTS: From January 1992 to December 2006, 5,248 patients of microtia were treated with 6,252 expander. After the maintaining period, the expanded skin was thin and well-vascularized. The complication rate was 7.79%, including hematoma, malunion and infection. CONCLUSIONS: The quantitative tissue expansion is easily manipulated with few complications. It can provide hairless, thin skin with reliable blood supply for ear reconstruction.
