Nasolabial symmetry following Tennison–Randall lip repair: A three-dimensional approach in 10-year-old patients with unilateral clefts of lip, alveolus and palate

To assess the degree of facial symmetry in patients suffering from unilateral cleft lip, alveolus and palate (UCLAP) by determining differences between the cleft and the non-cleft hemifaces from 3D surface data. In twenty-two 10-year-old UCLAP patients, who had the lip repaired using the Tennison–Ra...

Description
Summary:To assess the degree of facial symmetry in patients suffering from unilateral cleft lip, alveolus and palate (UCLAP) by determining differences between the cleft and the non-cleft hemifaces from 3D surface data. In twenty-two 10-year-old UCLAP patients, who had the lip repaired using the Tennison–Randall technique and did not undergo further revisional surgery, differences were determined between landmarks, surface areas of the upper lip vermilion and nostrils and virtual volumes of midface, nose and upper lip for cleft and non-cleft sides, separately, after having established a plane of symmetry calculated from optical 3D facial surface data. Statistically significant differences could be found between cleft and non-cleft sides for the nasal landmarks G lat, G sup and La med, the nostril angle and the virtual volume of the nose ( p Glat=0.011, p Gsup
