Although artificial materials are available for otoconstruction, the permanence of a single reconstructed ear is questioned due to the general rejection of artificial materials by the body and the thin skin covering, which is often prone to scaffold exposure. To date, autologous rib cartilage remains the preferred method of ear reconstruction. In the past, the removal of rib cartilage tended to leave an 8-10 cm long and wide scar on the chest, and demanding parents would forgo ear reconstruction surgery because of the excessively long surgical scar. With the development of endo-optical guidance assisted small incision cartilage removal techniques, the scar on the chest after ear reconstruction is only 3-4 cm long and thin. With the development of new technologies, cosmetic ear reconstruction has become a reality.
