Summary
Endonasal volume and nasal narrowing areas increase with age in healthy adults, as shown by acoustic rhinometry. This study provides new data on age-related changes in nasal architecture.
Area of Science:
- Otolaryngology
- Rhontology
- Gerontology
Background:
- Extensive research exists on skeletal nasal changes in the elderly.
- Limited data are available on age-related variations in endonasal architecture.
Purpose of the Study:
- To evaluate endonasal parameters in an elderly population.
- To compare endonasal architecture in elderly individuals with a younger cohort.
Main Methods:
- Acoustic rhinometry was used to measure endonasal volume (V0-7) and minimal cross-sectional areas (MCA1, MCA2).
- 165 participants aged 20-93 years were studied.
- Statistical analysis included Pearson correlation and ANOVA, with age as a variable.
Main Results:
- Endonasal volume (V0-7) and minimal cross-sectional areas (MCA1, MCA2) significantly increased with age.
- No statistical difference in gender distribution was observed between age groups.
- A slight decrease in these parameters was noted in men over 80 years old.
Conclusions:
- Acoustic rhinometry reveals a gradual increase in endonasal volumes and minimal cross-sectional areas with aging in healthy individuals.
- This finding highlights age-related changes in the internal nasal structure.
