Antihelix, Additional Crus

Definition:

Objective: Supernumerary ridge or crus of the ear arising from the antihelix

Comments:

The supernumerary crus usually emanates posteriorly from the antihelix at, or just above, the point of its bifurcation, but may have a different origin. In the former case, the finding is termed Stahl ear [Yamada and Fukuda, [1980]].
