Objective: Invagination of the superior part of the auricle under a fold of temporal skinComments:
There are associated anomalies of the upper antihelix and crura. The upper one-third of the auricle is primarily affected and there is an inferomedial displacement of the Helical Darwin tubercle. Two types are recognized: Type I, the antihelix and superior crus are reduced in size (Fig. a); Type II, it is the antihelix and inferior crus that are affected (Fig. b) [Hirose et al., ].
