Abstract:

Objective To explore a new method of correcting cryptotia by overturning constricted cartilage. By this method,

the mechanical direction of cartilage is changed. Methods Thirty cryptotia patients were treated from 2010 to 2022. The

retroauricular skin flap was elevated to expose the posterior aspect of the upper auricular cartilage. The abnormal insertion of

the auricular intrinsic muscles was detached. Cut and overturned the sharp antihelical cartilage, and the scalp skin flap was

undermined and advanced toward the postauricular sulcus. The edge of the retroauricular scalp flap was fixed on the mastoid

periosteum to release tension of the incision. Results The 22 unilateral and 8 bilateral cryptotia patients were followed up

for 6-48 months. Favorable results maintained without skin necrosis or other complications. No case needed revision surgery.

Conclusion This new method of overturning the cartilage flap is generally applicable to moderate and severe patients with

cryptotia, and its innovative point is to completely change the mechanical direction of constricted cartilage in the region of the antihelix
