Aesthetic Science of Rhinoplasty: Three Principles.

Aesthetic science is a rapidly growing discipline that involves plastic surgery as much or more than other disciplines of science. Fortunately, how and why the human brain responds to the visual world is better understood now than ever before. Of necessity plastic surgery is a part of that aesthetic science movement because it deals directly with the application of aesthetic principles. Therefore, it behooves the surgeon to be familiar with the principles of aesthetic science so as to both delineate and attain the aesthetic goal at the same time any functional goal is part of the operation. There are three important principles for rhinoplasty: (1) symmetry, (2) continuity and (3) persistence. This study provides examples of how they apply in the preop, intraop and postop phase of performing aesthetic rhinoplasty. A firm understanding of these principles can then guide the surgeon through the difficult maze of decision making, operative planning and surgical execution that arguably makes aesthetic rhinoplasty the most difficult aesthetic operation in plastic surgery.
