Rib Cartilage Framework Supporting Combined with Local Flap Grafting for Correction of Cryptotia

Objective:To investigate the curative effect of rib cartilage framework supporting combined with local flap grafting for correction of cryptotia.Methods:Fourteen cases (nineteen ears) were corrected by rib cartilage framework supporting combined with local flap grafting method from January 2017 to March 2019. Part of the 7th rib cartilage was carved into a scalloped cartilage piece, which was implanted on the retroauricular cartilage to release and expand the deformed cartilage. A "M" incision was designed on the retroauricular skin to make the local flap grafting.Results:All corrected auricles were followed up for four months to three year and abtained satisfactory and stable appearance. In one case, the edge of the helix was broken two weeks after the operation, and well healed after repairing.Conclusions:The rib cartilage framework supporting combined with local flap grafting method can fully correct the deformity of cryptotia, and the long-term effect is satisfied. It can be an important complement to the classic methods.
