Flaring ear, also known as augmentation ear deformity, is a relatively common congenital auricular deformity that is generally believed to be caused by incomplete formation of the ear chakra or overdevelopment of the cartilage of the ear nail during the embryonic period. It is more common bilaterally. In normal ears, the angle between the auricle and the ear canal is 90 degrees, while in patients with aural malformations, the angle between the auricle and the ear canal is greater than 90 degrees, usually above 150 degrees. In order not to affect the normal psychological development of the child, the surgery is usually performed at the age of 5-6 years. Principles of correction: Re-formation of the opposite ear chakra and its upper and lower legs, and reduction of the width of the earnail wall so that the distance from the ear chakra to the mastoid is less than 2 cm. Commonly used surgical methods: Mustarde method, Stentrom method, and Converse method, the latter being the commonly used procedure today.
