In the anatomy of the human ear, the concha is the deepest depression of the auricle. It functions as a hollow, funnel-like structure that leads directly into the external auditory canal.1

The concha is partially obscured by two small projections: the tragus, located in front, and the antitragus, located behind it. Additionally, the helix—a prominent ridge forming the outer rim of the ear—arises from the floor of the concha, while an inner ridge known as the antihelix surrounds it.1
