Quantitative Evaluation of Attention to Faces After Orthognathic Surgery With Eye-tracking

"Standardized photographs presenting 10 control subjects (class I) and patients with dentofacial deformities (10 class II and 10 class III) before and after surgery - from the front and from the side - will be used to form an approximately 10 min video sequence using the Tobii Pro Lab® software (Tobii Pro AB, Danderyd, Sweden). The naive participants will look at the percept during which the faces of the controls and the patients will alternate, with the only instruction being free visual exploration of the percept.~The fixation duration in the defined areas of interest (eyes, nose, mouth, chin) will be recorded with a Tobii® Pro X3-120 eye-tracking device and the results will be processed with the Tobii Pro Lab® software."
