Designing for Head and Neck Anatomy

The deep arteries of the head are well protected, and many surface arteries of the face and scalp are generally resistant to pressure, in part, because they are relatively protected by muscle and fat. Two arteries, the superficial temporal and the posterior auricular, can be affected with pressure (Figure 3.5, left side). The superficial temporal artery passes over the zygomatic process (Figure 3.3, right side), a part of the temporal bone which articulates with the zygoma in front of the ear. Use gentle pressure at this site, just in front of the ear to feel the artery pulse. Pressure on the artery may cause pain and restrict blood flow, both negative effects. However, pressure applied to this area with a wearable device has been used to treat migraine headaches (Cianchetti, Serci, Pisano, & Ledda, 2010). The posterior auricular artery, lying next to the posterior auricular nerve, about 1 cm (0.5 in.) behind the ear can be compressed with curving eyewear bows that reach the posterior auricular nerve tender point.

The squamosal forms a flat floor for the temporal fossa at the base of the zygomatic process. The preserved posterior part of the squamosal shows a deep fossa for the sternocephalicus (Figure 4F). In ventral view (Figure 4C), the broken base of the zygomatic process is laterally swollen, possibly at the base of the postglenoid process. Medial to the zygomatic process is a flat presumed tympanosquamosal recess.
