    Abstract:
    OBJECTIVE: To investigate the application of medpor and split-thickness skin graft in formation of cranioauricular sulcus during auricular reconstruction with Nagata method. METHODS: The first stage operation was fulfilled according to the Nagata two-stage method which involves fabrication and grafting of the costal cartilage framework. The second-stage ear elevation operation was undertaken 6 months later to form the cranioauricular sulcus. Split-thickness skin was taken from temporal and accipital area. After releasing the auricular framework and transplanting C shaped medpor at the rear side of framework, the temporaparietal fascia flap was transferred to cover postauricular medpor and framework. Then the split-thickness skin graft was implant on the fascia surface. RESULTS: From July 2010 to August 2012, 20 cases (22 ears) were treated. Partial necrosis of temporaparietal fascia flap and framework exposure happened in 1 case. Successful ear reconstruction was achieved in other cases with satisfactory cranioauricular sulcus during the follow-up period of 6-18 months (average, 13 months). CONCLUSIONS: The application of medpor and split-thickness skin graft in the ear elevation of Nagata method for auricular reconstruction for microtia can achieve satisfactory results. It not only avoids the obvious scar in the donor site due to harvesting full-thickness and intermediate-thickness skin, but also reduces chest trauma due to harvesting costal cartilage.
