ABSTRACT
PURPOSE:
To determine the dimensions and function of the auricular muscle and to consider applications of this muscle in facial plastic surgery.METHODS:
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.RESULTS:
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.CONCLUSIONS:
The auricular muscle acts as an occipitofrontalis stabilizer and a weak brow elevator. LEVEL OF EVIDENCE IV This journal requires that authors assign a level of evidence to each article.
