Facial Units and Subunits

The decision to reconstruct facial defects needs to consider various factors, which includes the final aesthetic outcome. Aesthetic aspects are more important in the face than almost any other part of the body. An understanding of the concept of facial aesthetic units and subunits and the factors influencing the placement of incisions/scars can help the clinician obtain the most cosmetically pleasing outcome. A detailed description of these and their relevance is provided in this chapter.
