Dr. Ho believes that while every face is unique, the ideal ears are in proportion with the other components of the face and do not distract from the face. The length of the adult ear is commonly 5.5 to 6.5 cm in length with the width 50 to 60% of the length. The ideal projection of the ear from the head as accounted for by the conchomastoid angle is 25 degrees in males and 20 degrees in females. The ideal conchoscaphal angle is 90 degrees. Ideal distances of the superior portion, mid portion, and inferior portion of the ear to the head are 10 to 12 mm, 16 to 18 mm, and 20 to 22 mm, respectively. Dr. Ho utilizes these anatomic principles as a foundation for her surgical technique as well as her aesthetic intuition in otoplasty.
