Is there Any Correlation Between Nasal Height and Facial-Nasal Horizontal Anthropometrics? An Anthropometric Analysis...

Area of Science:

• Anthropometry
• Plastic Surgery
• Medical Imaging

Background:

• Limited normative data exists for Turkish populations regarding nasal and facial anthropometry.
• The relationship between horizontal nasal/facial measurements and nasal height is not well-established.

Purpose of the Study:

• To investigate the correlation between horizontal nasal and facial anthropometric measurements and nasal height in the Turkish population.
• To establish normative data for rhinoplasty surgical planning.

Main Methods:

• A cross-sectional study utilizing 3D-CT scans of 249 adult Turkish patients.
• Calculation of nasal bone anthropometrics, including bizygomatic distance (K), nasal aperture lengths (L, M), nasion width (N), and nasal height (O).
• Analysis of anthropometric ratios (K/O, L/O, M/O, N/O) and comparison across sex and nasal shape (S vs. V-shaped).

Main Results:

• Male patients exhibited significantly higher nasal bone ratios than females.
• All horizontal measurements positively correlated with nasal height.
• The K/O ratio was identified as the most potent determinant for planning nasal height, with ROC analysis yielding a threshold of 1.65 cm.

Conclusions:

• Increased horizontal facial and nasal dimensions are associated with increased nasal height, more so in males.
• Bizygomatic width and widest nasal aperture length are critical determinants for estimating desired nasal height in rhinoplasty.
• Developed a formula to estimate ideal dorsal projection based on nasal height and facial width.
