Is seated behind the cheeks, beneath the temple, and anterior to the mastoid process. Its size varies in individuals. It is free above, behind, and below. Anteriorly and within, it is continuous with the neighbouring parts. Its outer surface has several prominences, the Helix, Anthelix, Tragus, Antitragus, and Lobe; and several cavities-the groove of the Helix, the fossa navicularis scu scaphoides, and the Concha. The skin which covers the pavilion is very fine, and studded with a number of sebaceous follicles. The auricle is fixed to the head by three fibro-areolar ligaments; - a superior, anterior, and posterior.
