Sixth-month morphoauricular syndrome.

Based upon a study of the embryologic anatomy of the external ear, the authors have suggested that the antitragus muscle be called the auricularis inferioris muscle which has a double nerve supply and a double function. Abnormal traction of this muscle can vary the final shape of the ear, dragging the border of the antitragus downward and everting it. This scaphoid and prominent ear deformity can be corrected by precise surgery described here by the authors.
