Otoplasty for lop ears

The classification of malformations of the auricle is reviewed. Hinderer's technique is described. It is based on long oblique skin and cartilage flaps of the upper pole of the ear, taken in opposite directions for expansion of the helical arch, thus preventing a later visible notching at the helical rim. The remaining scapha is straightened and the superior crus and antihelical fold are formed by scratching and sandpaper abrasion of the lateral surface. A deep concha is treated by a cartilage strip expansion from the posterior conchal wall.
