    Abstract:
    OBJECTIVE: For microtia patients with excessively insufficient postauricular skin, it is difficult to obtain a satisfied outcome with existing strategies. In this study, we developed a modified tissue expander method for auricular reconstruction. METHODS: The modified tissue expander method divided into 4 stages. In the first stage, a 30 ml or 50 ml kidney-shaped tissue expander was implanted in the mastoid region. A short time expansion (average 33.5 days) was conducted subsequently. In the second stage, the expander was removed and a modified cartilage framework without tragus was inserted through the same incision. A crescent-shaped cartilage pad was inserted into the incision of cartilage-harvest site at the same time. In the third stage, the reconstructed ear was elevated. Lobule rotation and remanent modification were performed in the fourth stage. The patients were followed up between half a year and 10 years. The outcomes of the reconstructed ears were scored with evaluation criteria. RESULTS: From January 2010 to December 2019, a total of 45 microtia patients with excessively insufficient postauricular skin were performed the modified tissue expander method. Fourty-two patients showed satisfied outcomes. Complications such as hyperpigmentation in the skin graft area (3, 6.7%), scar hyperplasia (3, 6.7%) and folliculitis (1, 2.2%) were found. There were no complications related to the tissue expander. CONCLUSION: The modified tissue expander method is an effective and safe technique for auricular reconstruction in patients having excessively insufficient postauricular skin, with satisfying medium-term results.
