concha 

A medical/anatomic term used in reference to the C-shaped inner portion of the ear. It is composed of cartilage and makes up the middle third of the vertical plane of the ear. This area, as well as many other parts of the ear, can be pierced to any body modifier's liking.

The concha's main purpose is to protect the ear canal from damage to the eardrum.
