Multiple ear malformations: The incidence is high, with some reports reaching 0.3% or more, and the morphology is complex and diverse. Classification 1. Anterior ear malformation: Usually occurs in the anterior part of the ear, mainly in the ear screen, the auricular cavity and the front of the ear screen. In the milder cases, there is only a small redundancy of the ear screen and the ear screen shape is normal, that is, the malformation of the attached ear we mentioned earlier. In more severe cases, the shape of the ear screen disappears, the bulge is large and resembles a small auricle, and there is a duplication of the auricular cavity and a depression in front of the ear. (Figure 1: Multiple ear deformity from mild to severe) (Figure 2: Typical severe multiple ear deformity) 2. Posterior ear deformity: The auricle shrinks and curls or is cup-shaped, salami-shaped, etc. This deformity will be specially introduced later. Treatment: Surgery is the only treatment method, and there is no clear optimal age. Early surgery can prevent ridicule by classmates such as kindergarten elementary school and reduce the psychological impact on the affected child. Surgery: 1. Simple multiple ear deformities (e.g., appendicular ear): excision and revision surgery. 2. Deformed ear screen transposition surgery. 3.Filling the recess of the duplicated earnail cavity with superfluous tissue and cartilage. 4.Filling the preauricular depression with allogeneic cartilage or autologous fat graft.
