Anatomical Points and Aesthetic Anatomical Areas in the Aesthetic Evaluation of the Face
The perception of an attractive face is influenced by the stability and harmony of facial features. Therefore, changing the existing harmony of the face and creating a new face may cause a different aesthetic perception. Percent skeletal bone structure, muscles and soft tissue analysis as a tool has always been used to determine facial aesthetic and therapeutic purposes.
Soft tissue analysis is primarily done through clinical examinations but indirect measurements.
For this purpose, facial features are analyzed on radiographic and photographic images. Anthropometric methods are used by making numerical measurements as cephalometry and photogrammetry. Thus, the stability and aesthetic ratios of the face are paid for. However, these assessments are not the most straightforward procedure to value facial soft tissues. In addition to the fuss about the patient’s exposure to radiation during this evaluation, the soft tissue structures of the face can only measure in the lateral profile of the face. With these negatives, measurements began to be made only with photographs without X-rays.
Recently, various studies have published information on the usual costs of soft tissue measurements in different societies.
Today, soft tissue measurements of the face have gained popularity with computer software works.
In the evaluation of the patient, the face should be without make-up. Photo measurements are made today.
Anatomical points in the Aesthetic Evaluation of the Face Aesthetic anatomical areas
Anatomical aesthetic points of the face and their determination;
Trichion ( Tri ), the midpoint of the forehead at the end of the hairline; Due to hair loss and regression of the frontal hairline, the origin of the slightly upper part of the frontal muscle should be taken rather than the origin of the hair in the determination of the Trichion.
Glabella (G), the most anterior point of the middle of the eyebrow on the forehead
Nasion ( N ) is the middle point on the root of the nose
Pronasal (PRN); the most anterior point of the tip of the nose
Midnasal (Mn); Midpoint on the outer circumference of the nose in the middle of the PRN and N
Columella(Cm); profiled lowest and anterior point of the columella separating the nostrils
Subnasal (Sn), the point where the upper lip meets the columella.
Upper lip (Ls), mucocutaneous border of the upper lip
Upper Stomion (Sts); the lowest point where the upper lip meets the lower lip
Lower Stomion (Sti), the highest point where the lower lip meets the upper lip
Lower lip (Li) mucocutaneous border of the lower lip
Supramental (Sm); the deepest point of the concavity extending from the lower lip to the chin
Pogonion (Pg), anterior point of the chin,
Menton (Me), the lowest point of the lower edge of the chin
Cervical ( C ), the point that connects the neck and jaw lines
Tragus (Trg) is the highest point of the tragus in the ear.
TH; line parallel to the horizontal ground plane passes through the tragus
TV; the vertical line passes through the nasion.
Cover; The intersection of TH and TV.

These anatomical areas on the face are divided into some sub-areas in order to be evaluated better. These are shown in the photo below.
1- Forehead area; 1a the middle part of the forehead, the side of the forehead, 1c the eyebrow part
2. Eye and eyelids area; 3a lower eyelid area, 3b upper eyelid area, 3c outer corner area, 3d inner corner area
4- Cheek area; 4a mid cheek area, 4b zygomatic area, 4c cheek area, 4d buccal area
5- Upper lip area; 5a philtrum, 5b upper lip lateral area, 5c vermilion area
6- Lower lip area; 6a lower lip central area, 6b vermilion area
These subunits are not only face value valuable. In addition, these areas have differences in terms of thickness, color, structure and underlying tissues of the skin. In facial aesthetic applications, applications should be made by considering these areas. In addition, the transition ends of these areas are also valuable. In surgical applications or aesthetic attempts, the risk of scarring after wound remodeling is higher at these ends.
There are also skin tension lines on the face. These are the lines of change of skin elasticity angles. Surgical processes should be performed in parallel with them.
