Sir: Facial analysis is of great importance for evaluation and planning in aesthetic surgery.1 Numerous studies have resulted in the vast array of reports available, the majority of which have been gathered from American Caucasians, and there are few regarding the Persian population.2–4 Porter reported the significant differences among various ethnicities and cited the need for ethnic data. Standard photogrammetry, using both anteroposterior and lateral views, incorporating a ruler or grid for adjustments, was performed (focal length, 95 cm; object distance to camera, 125 cm; zooming by means of Tele; real size printing). Standard facial landmarks were represented by points on printed photographs of 197 Persian beautiful female subjects, and measurements between facial landmarks were obtained and depicted in charts (Figs. 1 and 2).Fig. 1.: Standard landmarks, frontal view.Fig. 2.: Standard landmarks, lateral view.The criteria for being beautiful were based on the research committee's opinion. Charts were constructed on the basis of information regarding North American Caucasians.1 Findings were compared with those of Caucasians by using SPSS (SPSS, Inc., Chicago, Ill.) (one-sample t test, p < 0.05; 95 percent confidence interval). The results are listed in Table 1.Table 1: Results and Basic Data ComparedAll parameters regarding anterior and lateral views of face height were smaller compared with those of Caucasians (statistically significant), except for n-sn (n-sn = 59 mm versus 51 mm) and g-sn (g-sn = 65 ± 5 mm versus 63 ± 4 mm), which were longer (statistically significant). Therefore, the midface was a few millimeters longer in the study group, and the lower third of the face was a bit shorter (sn-st and st-gn); however, the “canons” still rule the face. The height of the forehead was the same, but the inclination and nasofrontal angle were higher. Surveying eyebrow and eye parameters showed reduced figures for eyebrow-pupil, eyebrow-crease, SOR, and IOR, and an increase for LOR, eye fissure, and upper lid-limbus. Although a statistical difference was reported, the standard deviations and means were within the values for Caucasians. However, clinically, eyes seemed to be more prominent (Table 1). In contrast, there was minimal scleral show, yet the overall beautiful appearance of the study group was not detrimentally affected (yet it is possible that otherwise they would appear prettier). The sum of these factors led to more prominent eyes in the study group. A review of nasal parameters showed statistical differences, but again, mean values and SD were within those of Caucasians. Generally, lips were somewhat shorter but more prominent in the study group (vermilion parameters and lip length, sn-st, st-sl). Overall, chin height was a bit shorter, clinically justifiable and regarding sn-st and st-gn values (statistically significant). Facial convexity was greater in the study group (g-sn < sn-pg, perp to FH through sn, inclination of the Lieber line) (statistically significant). The inclination of the Lieber line was 5 ± 1 degrees compared with 1.6 ± 2.5 degrees in Caucasians. In summary, the overall facies of the study group were as follows: small lower third of the face and chin, prominent eyes, prominent lips, and a more convex facial profile, all denoting a “baby face” appearance. It is obvious that for a reasonable deduction, we are still short of data, but according to the presented information, it seems that although some figures of Caucasians were still applicable to the Persian population, many of them might be changed for Persians if optimal operative results are to be achieved (Table 1).
