Pre and postoperative measures
EAR, LENS
Ear molding was performed using alginate (Dencrigel® brand) preoperatively and six months after surgery. The first cut is made transversely, in the middle of the cephalocaudal length of the ear. The second cut is made between the first cut and the upper end of the ear, at an equal distance.The cephalo-auricular angle measure used the first cut. It was defined as the intersection between the lateral portion of the mastoid with a line passing between the tragus and the middle of the helix. The scapho-conchal angle is obtained in the second cut, with the same structures in a posterior view of the ear.The molds were photographed using a Sony Cyber-Shot® 7.2 megapixel camera with Carl Zeiss Vario Tessar® 2.8–5.8/5.35‒21 lens, 4. The photos were sent for an external examiner to measure the scapho-conchal and cephalo-auricular angles, using the computer program Onde Rulers using the Protactor Ruler function.
