[Correction of cryptotia and cartilage malformation with Z-plasty without skin grafting].

Objective To explore the curative effect of Z-plasty without skin grafting for correction of cryptotia. Methods Twenty-five cases (29 ears) with cryototia were corrected by Z-plasty without skin grafting in our department from June 2009 to January 2014. A Z-shaped incision with one arm on the back of antihelix and the other arm on the edge of hair was made on the back of ear and scalp.The adhesion on the back of antihelix cartilage was dissected and the cartilage framework was lifted and re-positioned. The postauricular flap was transferred to cover the wound on the back of antihelix.The other flap was transferred to cover the remnant wound and correct the malformation of cryptotia. Results All the patients were followed up from 6 months to 1 year with stable and symmetric appearance. Conclusions The shape of auricle is natural after operation without skin grafting. It is a simple and ideal method for the treatment of cryptotia. Key words: Cyptotia; Auricle; Z-plasty; Surgical flaps
