[Expanded post-auricular skin flap combined with autologous rib cartilage framework for correction of concha-type microtia].

OBJECTIVE

To explore the clinical effect of the method by using an expanded post-auricular skin flap combined with autologous rib cartilage framework for correction of concha-type microtia.

METHODS

The operation were performed in three stages. The expander was implanted under post-auricular skin at the first stage and expanded skin flap was formed. At the second stage, the expander was taken out and the expanded skin flap was transferred with autologous rib cartilage framework and skin graft for correction of microtia. At the third stage, the reconstructed ear was revised and new concha was formed.

RESULTS

From August 2008 to August 2011, 108 cases with 113 concha-type microtia were corrected by this method. All patients healed primarily and were followed up for 6 months to 3 years. The reconstructed ears had a good appearance and position, and were symmetric to ear on the healthy sides.

CONCLUSIONS

Using expanded post-auricular skin flap combined with autologous rib cartilage framework is a reliable method for concha-type microtia.
