Which two bones on the head have no part in massage or styling techniques?

The sphenoid and ethmoid bones are depth-perceived structures located within the skull that do not directly interact with the skin or muscles of the face, which are the primary areas involved in massage or styling techniques. These bones, situated deeper in the cranial cavity, play critical roles in forming the base of the skull and contributing to the structure of the nasal cavity, but they do not serve as contact points for techniques used in beauty and wellness practices.

On the other hand, the nasal and zygomatic bones are directly related to facial aesthetics and are prominent landmarks during facial massages and styling. The lacrimal and turbinal bones, though involved in the structure of the facial area, also don't directly impact the primary areas of massage techniques in the same way. Lastly, the mandible and maxillae are directly connected to jaw movement and facial structure which are significantly involved in the processes of massage and styling. Thus, the sphenoid and ethmoid bones distinctly stand out as not being involved in these techniques.
