THE DIAGNOSIS OF FETAL ALCOHOL SPECTRUM DISORDER (FASD) is complex and guidelines are warranted. A subcommittee of the Public Health Agency of Canada's National Advisory Committee on Fetal Alcohol Spectrum Disorder reviewed, analysed and integrated current approaches to diagnosis to reach agreement on a standard in Canada. The purpose of this paper is to review and clarify the use of current diagnostic systems and make recommendations on their application for diagnosis of FASD-related disabilities in people of all ages. The guidelines are based on widespread consultation of expert practitioners and partners in the field. The guidelines have been organized into 7 categories: screening and referral; the physical examination and differential diagnosis; the neurobehavioural assessment; and treatment and follow-up; maternal alcohol history in pregnancy; diagnostic criteria for fetal alcohol syndrome (FAS), partial FAS and alcohol-related neurodevelopmental disorder; and harmonization of Institute of Medicine and 4-Digit Diagnostic Code approaches. The diagnosis requires a comprehensive history and physical and neurobehavioural assessments; a multidisciplinary approach is necessary. These are the first Canadian guidelines for the diagnosis of FAS and its related disabilities, developed by broad-based consultation among experts in diagnosis

“…However, patients usually evaluate their own soft tissue esthetics on the basis of how they look in a frontal view. Therefore, three-dimensional (3D) imaging methods, such as 3D computed tomography [3][4][5][6] and 3D facial scan images (3D-FSIs), [7][8][9][10][11][12] are used to analyze and evaluate the soft tissues of the entire face.…”

Objective: To evaluate whether mandibular setback surgery (MSS) for Class III patients would produce gradients of three-dimensional (3D) soft tissue changes in the vertical and transverse aspects. Materials and Methods: The samples consisted of 26 Class III patients treated with MSS using bilateral sagittal split ramus osteotomy. Lateral cephalograms and 3D facial scan images were taken before and 6 months after MSS, and changes in landmarks and variables were measured using a Rapidform 2006. Paired and independent t-tests were performed for statistical analysis. Results: Landmarks in the upper lip and mouth corner (cheilion, Ch) moved backward and downward (respectively, cupid bow point, 1.0 mm and 0.3 mm, P , .001 and P , .01; alar curvature-Ch midpoint, 0.6 mm and 0.3 mm, both P , .001; Ch, 3.4 mm and 0.8 mm, both P , .001). However, landmarks in stomion (Stm), lower lip, and chin moved backward (Stm, 1.6 mm; labrale inferius [Li], 6.9 mm; LLBP, 6.9 mm; B9, 6.7 mm; Pog9, 6.7 mm; Me9, 6.6 mm; P , .001, respectively). Width and height of upper and lower lip were not altered significantly except for a decrease of lower vermilion height (Stm-Li, 1.7 mm, P , .001). Chin height (B9-Me9) was decreased because of backward and upward movement of Me9 (3.1 mm, P , .001). Although upper lip projection angle and Stm-transverse projection angle became acute (Ch Rt -Ls-Ch Lt , 5.7u; Ch Rt -Stm-Ch Lt , 6.4u, both P , .001) because of the greater backward movement of Ch than Stm, lower lip projection angle and Stm-vertical projection angle became obtuse (Ch Rt -Li-Ch Lt , 10.8u; LsStm-Li, 23.5u, both P , .001) because of the larger backward movement of Li than labrale superius (Ls). Conclusions: Three-dimensional soft tissue changes in Class III patients after MSS exhibited increased gradients from upper lip and lower lip to chin as well as from Stm to Ch.

“…We then applied, for the first time, 3-dimensional laser surface scanning for analysis of the 2 masks, according to established technique. 3,4 The laser scanner used (VIVID 700; Konica Minolta Sensing Americas Inc, Ramsey, New Jersey) operates on the principle of a light-stripe triangulation range finder. The subject's facial surface is scanned from top to bottom with a class 2 laser light stripe projected from a distance of at least 1 m. The position of an illuminated surface point relative to the viewpoint is obtained by triangulation.…”
