Young children need general anesthesia. Older children or adults can have local anesthesia so that they can go home on the day of the operation. Ear pulling surgery takes 2-3 hours, and more complicated surgery takes longer. The most common method is to make a small incision behind the ear to expose the cartilage, cut the cartilage properly and bend it backwards, and then keep the new shape of the cartilage with suture. If the ear is too big or the cartilage is difficult to shape, some cartilage may be removed to make the ear contour more natural. Unilateral ear can only be operated unilaterally; But sometimes in order to make the shapes of both sides consistent, it may be necessary to do binaural plastic surgery at the same time.
