The eyebrow and eyelid are important sexually dimorphic and ethnic features of the face. In cosmetic surgery, maintenance of these landmarks is important to obtaining satisfactory results.
The upper eyelid crease height pretarsal skin and eyebrow height were studied in 305 Malay subjects (146 males and 159 females) varying in age from 2-80 years, who were randomly selected from the residents of Kota Bharu, Kelantan. In females, from the age of 11 years the mean pretarsal skin height increased progressively with age. In males, however, it decreased with age up to 60 years. In both sexes, subjects more than 60 years old showed highest values for pretarsal skin height. The mean eyelid crease height increased progressively with age from 11 years onwards in males but not in females. The mean eyebrow height increased with age in females but not in males. Eyebrow and eyelid measurements seem to show a definite racial variation. Besides establishing normal values for eyelid and eyebrow measurements in Malays, our findings indicate that age and sex should be taken into consideration to achieve satisfactory results in cosmetic eyelid surgery in Malays.
Fast and non-invasive systems of the three-dimensional (3D) technology are a recent trend in orthodontics. The reproducibility of facial landmarks is important so that 3D facial measurements are accurate and may-be applied clinically. The aim of this study is to evaluate the reproducibility of facial soft tissue landmarks using a non-invasive stereo-photogrammetry 3D camera.
