To completely correct the cup-shaped ear deformity, it is necessary to repair all anatomical defects in all parts. There are many surgical methods to correct cup-shaped ears. The common surgical method is to cut the back of the ear from the edge of the helix to correct the deformed cartilage and restore the normal shape of the ear. Antibiotics were routinely used for three days after operation, and the auxiliary materials and stitches were removed after ten days.
