Anthropometry of the nose pre- and post-photogrammetric adjustments in a sample of Syrian medical students. A cross-sectional study.

ABSTRACT

Background and Aims: The individual's perceived beauty, sense of identity, and general well-being are all influenced by the social implications of the esthetics of their facial appearance. One of the major indicators of one's facial beauty is anthropometric proportions. This study was conducted to measure and evaluate the anthropometric proportions in a Syrian population, and to determine their desired nasal shape. Methods: A cross-sectional study was conducted on Syrian university students. Lateral and frontal pictures of the participants were taken using Canon EOS 250D from a standard distance of 100 cm. These pictures were analyzed, then nasal measurements were adjusted according to the participants' desire using Adobe Photoshop 2020. All anthropometric measurements were conducted on AutoCAD® 2019 software before and after the adjustments. Data was analyzed using the SPSS-25 using paired samples T test to compare the means. Results: The study included 53 females and 47 males. The mean age was 22.25. The mean unadjusted nasofrontal angle, nasolabial angle, nasomental angle, nasofacial angle, nasal index, Byrd and Hobar ratio, and Powell-modified Baum ratio were 141.80, 102.18, 129.21, 34.60, 71.71, 0.62, and 3.08 in the rhinoplasty-negative participants, and 145.89, 102.03, 130.20, 32.44, 67.96, 0.64, and 3.06 in the rhinoplasty-positive participants, respectively. While the mean of the adjusted previously mentioned angles were 144.59, 106.32, 131.19, 31.15, 62.91, 0.60, and 3.19 in the rhinoplasty-negative participants, and 146.31, 102, 130.20, 31, 62.55, 0.62, and 3.08 in the rhinoplasty-positive participants, respectively. Conclusion: In contrast to other populations, our study concluded that Syrians had unique anthropometric measurements and facial esthetics preferences. Moreover, the local plastic surgeons were able to identify most of the preferred nasal measurements for rhinoplasty in this ethnic group. It is advisable to use photogrammetry before rhinoplasty to identify the preferred nasal measurements of each individual to ensure the patient's satisfaction with the outcome of the surgery.
