Anthropometric characteristics of the nasal region in Vietnamese individuals aged 18 25

Introduction: The anthropometric evaluation of craniofacial morphology and facial harmony has significant clinical implications in the fields of maxillofacial surgery, reconstructive rhinoplasty, and orthodontics, providing essential reference data for surgical planning and aesthetic optimization. Objectives: To determine the anthropometric morphological characteristics of the nasal region in Vietnamese individuals aged 18-25. Methods: A descriptive study was conducted on 405 students aged 18 to 25 years in Vietnam. Anthropometric morphological characteristics, including distances, angles, and ratios, were measured using an indirect measurement method. Results: Anthropometric analysis of the Vietnamese population aged 18–25 years revealed that the average nasal root-to-tip length was 40.51 ± 4.16 mm, and the average nasal width was 41.15 ± 3.63 mm. The mean nasal height measured 13.69 ± 1.17 mm. The nasofrontal angle averaged 141.20° ± 7.50°, while the nasolabial angle averaged 100.36° ± 12.03°. For proportional indices, the Goode ratio averaged 0.56 ± 0.05 and the Baum ratio averaged 2.12 ± 0.23. A significant positive correlation was observed between nasal bridge length and facial length (p< 0.001). Conclusion: The anthropometric characteristics of the nasal region in the Vietnamese population exhibit significant sexual dimorphism, particularly in terms of dimensions and proportional indices.
