To determine the dimensions and function of the auricular muscle and to consider applications of this muscle in facial plastic surgery.
Nonpreserved fresh frozen human cadaver dissections from the (HOSPITAL-Blinded) Body Donation program were dissected. The length and width of the superior auricular muscle were measured. One surgeon performed all dissections and measurements.
A total of seven left and five right hemifaces were studied. The average central height of the superior auricular muscle was 4.7 cm, and an average width was 5.0 cm. There was no significant difference between the average values of the left versus the right hemiface measurements. The muscle originated in the fibers of the galea and temporal fascia and inserted into the conchal cartilage in each specimen. Engaging the muscle in its line of action yielded slight elevation of the forehead and prevented movement of the galea along the vertex of the scalp.
The auricular muscle acts as an occipitofrontalis stabilizer and a weak brow elevator.

确定耳肌的维度和功能，并考虑该肌肉在面部整形手术中的应用。
对（医院匿名）遗体捐献计划中的非保存新鲜冷冻的人体尸体进行解剖。测量耳上肌的长度和宽度。由一名外科医生进行所有的解剖和测量。
共研究了 7 个左侧和 5 个右侧半面。耳上肌的平均中央高度为 4.7cm，平均宽度为 5.0cm。左侧和右侧半面测量值的平均值之间没有显著差异。该肌肉起自帽状腱膜和颞筋膜的纤维，并在每个标本中插入耳廓软骨。在其作用线上使肌肉收缩可轻微抬高额头，并防止帽状腱膜沿头皮顶点移动。
耳肌作为枕额肌的稳定剂和较弱的眉提升肌。
