Abstract

Purpose

The purpose of this study was to evaluate age-related changes of orbital rim in Koreans and construct a reference data set for the aging phenomenon in Asians.

Methods

Data were collected from computed tomography (CT) scans of orbits and facial bones obtained from 107 Korean (55 males and 52 females) at intervals of 0.60 mm. Subjects was categorized according to sex and age as follows: young group (20–35 years) and old group (60 years and above). CT scans were reconstructed via three-dimensional (3D) modeling programs. The most lateral, medial, superior and inferior points of orbital rim were used as reference points. The orbital aperture area in each 3D model was measured using an analytical software program such as 3-Matic.

Results

The orbital aperture height showed no overall statistically significant difference (P > 0.05) with age in either sex. Changes were irregular with a combination of decrease and increased components. The mean change did not exceed about 0.1 mm. The orbital aperture area showed no significant change with increasing age in either male or female study populations.

Conclusions

In this study, there was no significant enlargement of the orbital rim with increasing age in Koreans. The measurement data in the present study differ from previous studies involving White subjects, which revealed a significant increase in orbital aperture area.
