ABSTRACT: INTRODUCTION: Nasal anthropometry plays a pivotal role in assessing nasal size and shape within the context of overall craniofacial structure. However, defining the ideal nasal aesthetic remains complex. Anthropometric variations in nasal morphology across populations, shaped by environmental adaptations, contribute to diverse perceptions of facial harmony among different ethnic groups. AIM: To define average nasal values in a harmonious Moroccan population; to explore differences between female and male noses; to establish the ideal ratio between nasal height and width. METHODS: This descriptive cross-sectional study utilized digital photographs of patients from the dento-facial orthopedic service at the IBN ROCHD University Hospital in Casablanca. Convenience sampling was employed, involving 51 subjects selected by an expert panel. RESULTS: Average values for nasal measurements were as follows: width of nasal root (14.8 ± 2.93 mm), width of nose (33.8 ± 4.43 mm), nasal protrusion (19.8 ± 2.23 mm), length of nasal bridge (42.9 ± 5.51 mm), nasal height (49.6 ± 4.85 mm), nasolabial angle (98.1˚ ± 12.5˚), nasofrontal angle (143˚ ± 16.4˚), nasofacial angle (34.9˚ ± 3.78˚), nasal projection angle (73˚ ± 7.54˚), and nasal index (68.5 ± 7.38). Statistically significant differences based on gender were observed in width of the nose, length of nasal bridge, nasal height and nasal projection angle. The “leptorhine” nose type is the most common within our sample. CONCLUSION: Findings underscore the distinct variations in nasal morphology between sexes and highlight the prevalence of specific nose types within our study population.
