Stretchy ears is a common congenital auricular deformity with genetic predisposition, which mainly manifests itself as a craniocranial angle of more than 90 degrees, and the loss of the shape of the opposite ear wheel, which affects the overall harmonization and aesthetics of the facial features. Usually, it can be corrected by otoplasty, through the ear cartilage molding, the formation of the opposite ear wheel, lowering the ear cranial angle, and correcting the anterior tilt of the earlobe. The procedure is relatively safe compared to other otoplasty procedures. This surgery is less invasive, but there may be the following risks: 1, surgical incision scar hyperplasia, the incision is usually about 3cm, which may lead to scar proliferation. 2, the effect is not good, the beckoning ear correction is not enough or the shape of the ear wheel is not good, may need to be adjusted again; 3, the correction is not enough: mainly because of the doctor’s technology or other reasons, resulting in the correction of the ear is not up to the standard of the normal ear; 4, the correction of excessive: may be due to too much suture or excision, resulting in overcorrection; 5, hematoma: during the operation due to poor wound bandaging or insufficient haemostasis cause Hematoma, usually need to pay attention to, so as not to cause auricular cartilage necrosis; 6, infection: may be due to the operation is not strictly sterilized or not to ensure the aseptic operation and caused by, in severe cases, can lead to auricular necrosis deformity; 7, bilateral asymmetry.
