Furrow of the Auricle Posterior

Grooves and canals of the auricle

The auricle is a paired fold of skin in the human outer ear. The grooves of the auricle are formed by the medial and lateral fimbrialis. In addition, the formation of a dorsal groove and a lateral groove is possible. There are clinical variants of changes in the auricular groove (scars, cicatricial deformities, reversible posterior fold syndrome).

Clinical significance The groove is a vertical connective tissue (fibrous) canal connecting the ear canal with the skin of the auricle. It is limited on the side of the subcutaneous tissue by the zygomatic arch and the skin of the inner surface of the auricle, on the side of the middle ear by the mucous membrane of the external auditory canal. The presence of a groove on the anterior surface of the ear may be associated with lipomatosis, and on the posterior surface - with local injuries.

Lateral sulcus -

The furrow of the auricle (posterior auricle) (French sulcus auriculaire postérieur, Latin sulcithauricus posterior) is a small longitudinal groove located on the back surface of the auricle.

The groove of the ear gland begins in front of its upper edge and, following a spiral, reaches the lower edge, in the groove of the auricle
