Abstract: Objective To introduce a novel two-stage expansion method for secondary total ear reconstruction. Methods From July 2010 to April 2012, 7 cases with undesirable reconstructed ears were repaired by tissue expansion method. Procedures including stage 1 （removal of previous cartilage framework, tissue expander insertion） and stage 2 （removal of tissue expander, cartilage framework insertion regarding local conditions）. Results The follow up ranged from 6 months to 2.5 years. All the eases were well recovered with good three-dimensional forms, symmetrical auriculo-cephalic angle and stable fixation. Conclusion This novel expansion method is safe, stable and less traumatic for secondary total ear reconstruction. With sufficient expanded skin flap and re-fabricated cartilage framework, lifelike appearance of reconstructed ear could be acquired without causing additional injury.
