The anterior auricular muscle, the smallest of the three auricular muscles, is thin and fan-shaped, and its fibers are pale and indistinct. It arises from the lateral edge of the epicranial aponeurosis , and its fibers converge to be inserted into a projection on the front of the helix .
The extrinsic auricular muscles are the three muscles surrounding the auricula or outer ear: anterior auricular muscle; superior auricular muscle; posterior auricular muscle; The superior muscle is the largest of the three, followed by the posterior and the anterior. In some mammals these muscles can adjust the direction of the pinna.

Otoplasty (surgery of the ear) was developed in ancient India and is described in the medical compendium, the Sushruta Samhita (Sushruta's Compendium, c. 500 AD).The book discussed otoplastic and other plastic surgery techniques and procedures for correcting, repairing and reconstructing ears, noses, lips, and genitalia that were amputated as criminal, religious, and military punishments.
It merges with the occipitofrontalis muscle. In front, it forms a short and narrow prolongation between its union with the frontalis muscle (the frontal part of the occipitofrontalis muscle). On either side, the epicranial aponeurosis attaches to the anterior auricular muscles and the superior auricular muscles .
The great auricular nerve is a large trunk that ascends almost vertically over the sternocleidomastoid. [2] It winds around the posterior border of the sternocleidomastoid muscle, then perforates the deep fascia before ascending alongside the external jugular vein upon that sternocleidomastoid muscle beneath the platysma muscle to the parotid gland.

The helicis major (or large muscle of helix [1]) is an intrinsic muscle of the outer ear. In human anatomy , it is the form of a narrow vertical band situated upon the anterior margin of the helix , at the point where the helix becomes transverse.
The auriculotemporal nerve arises from the posterior division of [2]: 497 the mandibular nerve (CN V 3) (which is itself a branch of the trigeminal nerve (CN V)). [3] It arises by two roots [2]: 497 that circle around either side of the middle meningeal artery [1] [2]: 363 before uniting to form a single nerve.
