UNLABELLED: The aim of the study was to find a proper method that may evaluate the severity of facial asymmetry quickly and accessibly in clinics. METHODS: The three-dimensional image data of facial asymmetry patients were collected with three-dimensional laser surface scanning, and the desired therapy outcomes were simulated in computers by flip-registration procedure. The discrepancy between desired results and initial images was calculated automatically, and a colored hypsography was printed. A questionnaire was given to both the patient and the craniofacial surgeon to examine the symmetry, accessibility, achievability, and helpfulness of these outcomes. RESULTS: The three-dimensional image data offered by laser surface scanning were accurate and convenient. The desired results were reliable and acceptable to the patients. The colored hypsography was clear and accessible and achieved high appreciations from the surgeons. CONCLUSION: Three-dimensional laser surface scanning together with flip registration procedure can evaluate the severity of facial asymmetry quickly, quantitatively, and effectively with an achievable outcome. It is welcomed by the craniofacial surgeons and has a great potential in clinic application.
