Changes in Nasal Morphometry With Aging for a More Accurate Rhinoplasty.

Area of Science:

• Plastic Surgery
• Anatomy
• Medical Imaging

Background:

• Nasal morphometry is critical for rhinoplasty outcomes.
• Age-related changes in facial anatomy are not fully understood.
• Longitudinal studies are needed to track nasal changes over time.

Purpose of the Study:

• To investigate age-related changes in nasal morphometry over at least 10 years.
• To provide data for improved rhinoplasty planning.
• To analyze these changes in relation to sex and age groups.

Main Methods:

• Retrospective review of 50 adult patients from the Turkish population.
• Analysis of at least 2 head and neck 3D CT scans taken 10+ years apart.
• Measurement of various linear and angular parameters of the nasal region.

Main Results:

• All measured nasal parameters showed statistically significant differences after an average of 12.16 years.
• Aging led to increases in nasal floor anterior angle (NFRA), nasal tip projection (NTP), and nasal base width (NBW).
• Aging led to decreases in nasal floor anterior angle (NFAA), nasal length (NL), and nasal tip angle (NTA).

Conclusions:

• Significant age-related changes in nasal morphometry occur in both men and women over a 10-year period.
• These findings underscore the importance of considering age-related anatomic variations in preoperative rhinoplasty planning.
• Incorporating these insights can enhance surgical precision, individualization, and safety in rhinoplasty.
