Abstract:
In a study using lateral cranial radiographs of 454 males and 475 females (age 0-20 years) the anterior nasal spine-nasion (ANS-N) and ANS-posterior nasal spine (ANS-PNS) distance were measured and related to age and gender. The development of both dimensions is best described by negative exponential functions. ANS-PNS distance to the age of 5 and the ANS-N distance to the age of 2, develop linearly without gender difference. After this, deceleration, statistically more significant in females (P < 0.01, ANCOVA non-linear regression analysis) occurs for both parameters. Although a study of this type does not have maximal sensitivity, no significant calendar-age-related 'growth spurts' were detected.
