Facial anthropometric analysis of Iranian women with focus on effects of rhinoplasty

Background: Antropometheric measures can widely vary among different populations. Given the rising popularity of nonsurgical and surgical aesthetic procedures, standard facial anthropometric measurements are necessary for evaluating the outcomes of cosmetic and rejuvenating procedures. This study aimed to determine the anthropometry profile of Persian women, focusing on key facial parameters. Our secondary goal was to explore any change in these dimensions secondary to rhinoplasty. Methods: Facial anthropometric measurements were successfully evaluated in 207 healthy Iranian adult women. Using nine landmarks (trichion, glabella, nasion, subnasale, labiale superius, labiale inferius, gnathion, endocanthion, and exocanthion), ten standard anthropometric measurements and two angles were obtained. The measurements were analyzed separately for those with a history of rhinoplasty and those with a natural nose. Results: The height of the upper third, middle third, and lower third of the face was 7.04 (36.43%), 5.61 (29.04%), 6.67 (34.53%) cm, respectively. Other key measurements included: total face height 19.33 cm, nasal height 5.62 cm, philtrum length 1.61 cm, lower lip to gnathion 3.50 cm, right palpebral fissure length 3.79 cm, left palpebral fissure length: 3.82 cm, interocular diameter 3.71 cm, nasolabial angle 80.06°, and frontonasal angle 135.47°. There was no significant difference between the measurements for those with or without rhinoplasty. Also, the different age groups (18-25, 25-40, and 40-65 years) were statistically similar in these measurements. Conclusion: The difference in anthropometric measurements of this study with previous reports reveals the necessity of using specific anthropometric standards for Persian/Iranian women.
