This study aims to evaluate the relationship between the nasal profile and other craniofacial structures. Lateral cephalometric images of 124 adults were collected for this purpose. Statistical analyses such as regression analysis and canonical correlation analysis (CCA) were conducted on nasal and craniofacial anatomical parameters and their relationships. The regression analysis revealed that nasal length was related to maxillary height; nasal depth was related to the position of the maxilla and anterior cranial base length; and nasal base angle was related to upper dentoalveolar height. CCA revealed that nasal parameters (nasal length, depth, and hump) correlated more strongly with craniofacial parameters (maxillary height, anterior-posterior position of the maxilla, and maxillary length). Individuals with maxillary development curved anteriorly upwards had a straighter and smaller nasal profile, while those with maxillary development curved posteriorly downwards had a more arched and large nasal profile. The shape of the nasal dorsum was affected by the maxillomandibular rotation, while the increase in nasal base inclination was accompanied by an upward rotation of the maxillary plane, an increase in the upper dentoalveolar height, and an increase in the lower facial height. While it was observed that each nasal parameter was correlated with the underlying craniofacial structures to some extent, it was also observed that it would be more useful to evaluate the cumulative effects posed by craniofacial parameters. Various combinations of skeletal and dental structures are related to the nasal profile in varying forms and knowing these relationships will help reshape the face and provide aesthetic harmony.
