Facial muscles are clinically important and responsible for various functions of the face. However, it is difficult to grasp the complex anatomy of facial muscles using conventional methods, such as cadaver dissection. This study comprehensively explained the facial anatomy by utilizing a cadaver sectioned image and schematic drawing. The face was categorized into orbital, maxillary, upper oral, and lower oral regions. The spatial relationship between facial muscles was explained using cadaver sectioned images. The findings were correlated with schematic drawings for a better understanding. Minute facial muscles in each region were examined using sectioned images. The different muscle depths are explained in the schematic drawings. Additionally, the relationship between the facial muscles and facial artery was analyzed. The positional relationship between the muscles was expressed in different colors in the schematic drawings. Owing to the high resolution of the cadaver sectioned images, it was possible to understand the positional relationship of the fine facial muscles. Unlike in traditional cadaver dissection, it is not necessary to damage the outer structure to observe its inner structure. This study will help clinicians identify facial muscles and arterial structures.
