Figure 2
Photographs of an ultrasonographic examination of areas in the oral and maxillofacial regions. (a) The ultrasonographic probe (arrows) directly contacted the skin over the parotid gland in the coronal angle. (b) The ultrasonographic probe (arrows) directly contacted the skin over the submandibular gland in the coronal angle. (c) The ultrasonographic probe (arrows) directly contacted the skin over the masseter muscles in the axial angle. (d) The ultrasonographic probe (arrows) directly contacted the skin over the superior internal jugular vein in the axial angle.
