The absence of 1 posterior auricular sulcus has brought great inconvenience to patients. Besides wearing glasses, water can easily flow into the external auditory canal when bathing, so surgery can not only improve the appearance but also solve the dysfunction.

The surgical method is to dissect the upper part of the auricular cartilage hidden in the temporal scalp and establish a stable posterior auricular sulcus. Specific methods can be divided into skin grafting and local skin flap approval.

Routine use of antibiotics for 3-5 days, suture removal after skin flap operation for about one week, and suture removal after skin flap grafting for 12 days should not be impacted by external force in a short period of time.
