    The skin covering the lobe and the inner surface of the concha is freely supplied with sebaceous glands; these are liable to be converted into sebaceous cysts. The tragus (the prominence in front of the meatus) is covered on its posterior surface with a tuft of hairs. These hairs occasionally help to form accumulations which obstruct the meatus. Fig. 3.—The Auricle. a. Helix; i. fossa of helix; c. anti-helix ; rf. fossa of anti-helix; f. tragus;/. anti- tragus ; g-. concha leading to the external meatus ; h. lobe. The cartilage of the auricle is continuous with that forming the outer portion of the meatus, and is attached to the temporal bone by fibrous ligaments. There are numerous small ligaments and bands of muscular fibres connected with the cartilaginous skeleton, but these are of no pathological interest and therefore do not need further mention.
