Correlation Between Nasal Index and Vertical Growth Pattern: A Retrospective Study

Aim The aim of this study is to examine the relationship between nasal index and vertical growth pattern. Thus, the physician can be provided with a prediction that may assist in evaluating treatment options. Materials and Methods In this retrospective study, 300 individuals were randomly selected. The nasal index, calculated as the ratio of nasal width to height, was derived from photographs. Cephalometric radiographs were used to measure the SN/GoGn angle. Data analysis utilized the Anonymous, 2011 program, employing Pearson correlation tests to assess parameter correlations. Results There was no statistically significant correlation between the nasal index and the SN/GoGn angle in subgroups categorized by vertical growth patterns. However, a negative linear correlation was observed between the nasal index and the SN/GoGn angle within the leptorrhine subgroup ( P < .01). Additionally, when subgroups were not considered, a significant negative linear relationship between the nasal index and the SN/GoGn angle was found ( P < .01). Conclusion There was a significant correlation between vertical growth pattern and nasal index in individuals with leptorrhine nose type. In clinical examination, measurement of the nasal index can provide a prediction of the vertical growth pattern of the individual without cephalometric analysis.
