"Fengfeng Ear", commonly known as "Yuanbao Ear", is a common external ear deformity, which can occur on one side or both sides. The deformity is mainly manifested in the loss of normal anatomical shape of auricle, and the concavity and convexity of the upper part of auricle disappear and become relatively flat. The ears protrude laterally, and some people describe them as small cattail fans.
