| Popis: | Objectives. This study investigated age-related differences in nasal morphometry and the degree of changes within an individual over at least a 10-year period by pairing previous and recent three-dimensional reconstructed computed tomography (CT) images. Methods. Forty-eight adult Korean patients who underwent at least two CT scans of the nasal region with an interval of at least 10 years were selected. Patients were categorized into six subgroups according to sex and age (20–39 years, 40–49 years, and ≥50 years) at the time of initial imaging. Eight nasal parameters were measured on the initial and recent images, and paired comparisons between the two images were performed based on the data. The differences in the degree of change by age were also analyzed. Results. Over an average image interval of 12 years, men exhibited an increase in the nasofrontal angle (3.2°±5.4°, P=0.041), profile nasal length (1.7±1.7 mm, P=0.002), and nasal bridge height (1.2±1.6 mm, P=0.002). Conversely, they showed a decrease in the nasofacial angle (–2.3°±2.9°, P=0.010). Women also demonstrated an increase in the nasofrontal angle (2.5°±5.2°, P=0.010), profile nasal length (1.4±1.9 mm, P |
