Does intranasal cavity volume increase with age, and is it related to body mass index (BMI)?
Intranasal volume increases approximately linearly with age in adults. This study demonstrates that intranasal volume is larger in males than in females in the same age group, but is not related to BMI. It is likely that the larger intranasal volumes in males versus females relates to the overall larger size of males, but is not related to BMI, as there is no fatty tissue in the nasal cavity.

Background: Although many studies have described changes in the external nose with age, few have focused on intranasal changes. The study researchers used volumetric analysis of CT scans to demonstrate a significant change in intranasal volume with increasing age.
Study design: Retrospective chart review.
