 Or a so-called conchal rotation is performed by first removing muscle and connective tissue from the sulcus posterior (region where the ear is attached to the head), and then the ear is turned towards the head with sutures running between the pericranium and the cartilage of the concha, thus reducing its distance to the head.Using several mattress sutures that are anchored in the cartilage, a new antihelix fold is formed, or a weakly developed antihelix fold is bent more strongly.After the insertion of a drainage tube for 1 or 2 days, the skin wound on the back of the ear is sutured.
