Involves analyzing a patient's face to understand its structure, features, and the overall feeling it conveys. This includes evaluating symmetry, asymmetry, and any functional issues.

The study of proportions and harmony in facial features. It uses mathematical formulas and geometric principles to analyze and enhance the beauty of the face.

The process of aging naturally affects facial aesthetics. It includes changes like loss of skin elasticity, fat tissue reduction, and changes in bone structure.

The application of the Golden Proportion (approximately 1.618) to facial features, as it's believed to enhance aesthetic appeal. The Golden Proportion is found in nature and art.

The mathematical sequence discovered by Leonardo Fibonacci. It creates a unique spiral often found in nature, including the human body. It underlies the Golden Proportion.

A condition where the inner corners of the eyes are too far apart, resulting in a wider-than-normal distance between them.

The angle formed by lines from the Nasion (point between the eyebrows) to the Glabella (bridge of the nose) and from the Nasion to the nasal tip (tip of the nose).

The angle formed between a line from the tip of the nose to the philtrum (the vertical groove between the nose and upper lip) and a line from the philtrum to the upper lip.

The angle formed between the anterior facial plane (from the bridge of the nose to the chin) and a line tangent to the nose's dorsum (from the nasal tip to the Nasion).

The point where the columella (the vertical part of the nose) connects to the upper lip.

The middle point of the crease between the lower lip and chin.

The most forward point of the chin.

The most downward point of the chin.

A horizontal line drawn from the highest point of the ear canal to the lowest point of the eye socket.

The face is divided vertically into five equal parts, with the width of each eye accounting for one part.

The upper third of the face extends from the hairline to the glabella.

The middle third of the face extends from the glabella to the subnasale.

The lower third of the face extends from the subnasale to the menton.

The forehead is the upper third of the face, extending from the eyebrows to the hairline.

The natural curve of the nose, from the bridge to the tip, as seen in a side profile.

The angle formed between the lower jawline and the neck.

A prominent ridge above the eyes, most noticeable in men.

The way facial expressions, gestures, and movements reveal personality traits and emotions.

The study of facial features using X-rays, photos, and standardized measurements.

The line that follows the contours of the face from the forehead, to the chin, in profile.

Specific points on the face used as references in facial analysis, such as the hairline, brow line, and nose root.
