Soft-Tissue Response in Orthognathic Surgery Patients Treated by Bimaxillary Osteotomy. Cephalometry Compared with 2-D Photogrammetry

A better statistical method of predicting postsurgery soft tissue response in Class II patients

“…However, cephalometry is still a feasible standard for evaluating and predicting outcomes in routine orthognathic surgery cases. 29 In the end, a 3D prediction model would be more useful afterwards. We are establishing the foundation for the 3D prediction model.…”

Natural Head Postures of Patients With Facial Asymmetry in Frontal View Are Corrected After Orthognathic Surgeries

“…9 Briefly, the patients were asked to sit on a chair to maintain a straight back and to look straight into her/his own eyes reflected in a mirror with a relaxed facial expression with fully open eyes and gently closed lips. 9,20 The patients turned 90 degrees to the right toward the lens of a camera, taking caution to keep the former position.…”

“…20, 21 All photographs were saved in JPEG file format. 20 The images were analyzed using PicPick ver.3.1.7 design tool software (Wiziple Software, Seoul, Korea). The IP and TH (perpendicular to TV, actual horizontal line of the photograph) as reference lines were constructed on the program.…”
