Facial form analysis of the lower and middle face.

Structural form analysis identifies the major structural members of the middle and lower face through their high- and low-light areas, provides measurements and relationships between the key points, and explains the angular relationships in constructing a geometric form corresponding to these members. The six key points define the superior and inferior and anterior and posterior angles. The angles and planes then lead to a geometric form of the lower and middle face. The final construction provides a framework for examining the facial form and making aesthetic judgments which lead directly to surgical decisions. A study of 50 Caucasian women ages 22 to 30 was performed. Specific patient examples with analyses are provided.
