Typically in a beautiful and charming face, relationships and certain ratio for each . Of course, there is the need for these relationships, it is not absolute and may be in a person's face is compelling but the ratio may not be fully accurate scientific view . In this section, a number of these relationships and to be noted . If the view of facing by four vertical line we split into five regions . These lines from the internal corner of the eyes for two vertical line and the external corner of the eye to two other vertical line can be drawn .

Ideally the inner corner of the eyes of the ancient are refused, from the sides of the nose are rejected as well as blade ideally, the width is equal to the area of these five together .
At the same time if you view of facing by the two horizontal line is divided into three areas . One of these lines from the upper part of the nose in the area between the eyebrows ( nasion ) And another line from the junction of the nose and the upper lip ( sub nasal ) Gets rejected . These three areas include 3/1 upper, 3/1 The lower and middle are almost equal. The lower part of the face is divided into two areas, upper and lower, by a line passing horizontally through the junction of the lips. . The height of the lower area of the (Includes lower lip and Chin ) Double upper area (Includes upper lip) It is the length of the upper lip in women 20 mm and in men 22 is mm . The distance between the eyebrows to Chin in terms of height with the width of the face in the area of species is . The width of the nose in the area of ​​the wings, equal to half 3/1 The middle of the face and at the same time is equal to the height distance between the lower edge of the eye socket bone and below the nostrils when a person looks forward, two lines that run from the inner corner of the dark part of the eye. ( corea ) Are perpendicular to the bottom, the ideal view of the corners of the lips are also rejected in lateral view, the line of junction of the nose and the upper lip is perpendicular to the ground, you have a brief contact with the established upper lip . lower lip 2 Back mm and chin 4 They are located a millimeter behind the mentioned line in the profile view of the distance from the neck to the chin ( chin – neckline ) 50 Mm . If in the view of the external nose, the lower of the eyes ( paranasal ) It should not be submerged. . There is less bone growth marks, dents in this area is . In the case of this disorder is associated with a deficiency of the maxillary, rejected the need for surgery of the jaw is in keeping with the problem of the jaw, the bone transplant or implant troughs by the reform is . If there is a problem in the relationship and the growth of the jaw, Jaw surgery performed before the cosmetic surgery is advised. the maxillary surgery makes getting nose to be widescreen . So do the practice رینوپلاستی before surgery of the maxilla is not logical . One of the needs of the case, there is symmetry . In most people the symmetry for a hundred percent not seen . The aim of the treatment of asymmetry that took into consideration . It is worth noting, the human eye in different areas for the asymmetry of more than two millimeters note and this thread when you take into consideration asymmetry correction
