Evaluation of eyebrow position using angular measures

To evaluate the eyebrow position in children and elderly using angle measurements. The eyebrow position was evaluated by digital images in 4 to 6-year-old children (children group) and in patients with 50 years or more (elderly group), separated by age range. The images were taken in the primary gaze position with a Sony Lithium camera and then transferred to a MacIntosh G4 computer and processed by the NIH 1.58 program. The eyebrow position was evaluated using angle measures. Comparisons were done according to age, sex and laterality and the data were submitted to statistical analysis. The comparison of the angular measures showed that there was a significant difference in the position of eyebrow position between the studied groups with the same age. But comparing children and elderly there were differences in all performed measurements. The eyebrow external angle positions showed differences between children and elderly with a positive association between eyebrow position and age.
