The facial structures displayed in medical illustrations or revealed by cadaver dissection are their natural appearance. These are in their natural condition without exerting manipulation such as pinching or pulling on them. On the contrary, the tissue status being pulled or pinched during procedures is different from their original appearance. As well as the difference in the appearance, changes occur in the internal tissues.

In general, clinicians tend to perform aesthetic procedures while pinching the skin for the ease of the procedure. However, what happens below the skin at that time is not clearly known.

Therefore, we named the anatomy in the new status changed through pinching or pulling the tissues upward as “pinch anatomy” and studied tissue changes therefrom (Fig. 7.1).
