摘要

Background

The relationship between horizontal nasal and facial anthropometric measurements and nasal height remains unaddressed, and normative data specific to the Turkish population are currently limited in the existing literature.

Materials and Methods

A review of nasal bone anthropometrics was conducted using three-dimensional computed tomography (3D-CT) images from 249 randomly selected adult Turkish patients who applied for rhinoplasty in 2025. In this cross-sectional study, high-resolution CT scans were reconstructed into three-dimensional views employing standardized imaging parameters. The mean bizygomatic distance (K), the widest length of nasal aperture (L), the narrowest length of the nasal aperture (M), the width at nasion level (N), and the nasal height (O), also key anthropometric ratios (K/O, L/O, M/O, N/O), were calculated and compared across sex and nasal bony shape groups (S vs V-shaped). Receiver operating characteristic (ROC) analysis was conducted to establish discriminatory thresholds, with particular emphasis on nasal height.

Results

Of the cases, 141 were male, and 108 were female. A total of 178 patients had an S-shaped configuration, while 71 patients had a V-shaped configuration. Male patients had significantly higher nasal bone ratios than females (p < 0.05). No statistically significant differences were observed between S- and V-shaped morphologies. All horizontal measurements were positively correlated with nasal height. ROC analysis identified nasal height as a moderate discriminator, with a threshold of 1.65 cm. The main finding was that the K/O ratio was the most potent determinant for planning nasal height. Additionally, a formula was developed to estimate the ideal dorsal projection, assessing nasal height and its proportion relative to overall facial width.

Conclusions

The study’s results indicate that as horizontal dimensions increase, nasal height also increases, a phenomenon that is more pronounced in men. Additionally, the most critical determinants were the bizygomatic width and the widest nasal aperture length, which can be used to estimate the desired nasal height for surgical planning in rhinoplasty.
