sheared off the head, because the upper half of the pinna is projecting outwards, and, at the middle point, the lower half of the pinna is canted inwards, towards the hypoplastic, underdeveloped side of the face of the patient. A similar type of asymmetric development of the head and face features a relatively broad head, a narrow face, and a narrow mandible; when observed from the front perspective, the head and face of the person present a triangular configuration. Such wide-to-narrow skeletal sloping, from the head to the face, might create the bone promontory upon which rests and from which projects the upper anatomy of the pinna, which otherwise is an external ear of normal proportions, size, and contour. Protruding cauda helicis The cauda helicis (tail of the helix) is bound to the fibrofatty tissues of the earlobe by a network of connective tissue. The tail of the helix (cauda helicis), which projects outwards from the concha, carries the earlobe with it, causing it to protrude, which physical condition contributes to prominence of the lower pole of the pinna, the external ear. Protruding earlobe Given the morphological diversity of the earlobes found among men, women, and children, some earlobes are large, some earlobes are pendulous, and some earlobes are large and pendulous, but some are prominent because of the structure and form of the dense, interlacing connective tissue fibers that shape the earlobe anatomy independent of the tail of the helix (cauda helicis). Soft tissues Functionally, the external ear is served by three ear muscles, the auricularis posterior muscle (rear ear-muscle), the auricularis superior muscle (upper ear-muscle), and the auricularis anterior muscle (front ear-muscle), the most notable of which is the auricularis posterior muscle, which functions to pull the ear backwards, because it is superficially attached to the ponticulus (bridge) of the conchal cartilage, and to the posterior auricular ligament (rear ligament of the ear). The posterior muscle of the ear is composed of two to three fascicles (skeletal-muscle fibers contained in perimysium connective tissue), originates from the mastoid process of the temporal bone and is inserted to the lower part of the cranial surface of the concha, where it is surrounded by fibroareolar tissue deep within the temporal fascia. The posterior auricular artery irrigates the ear tissues with small, branch-artery blood vessels (rami). Likewise, the rear muscle of the ear is innervated with fine rami of the posterior auricular
