Purpose: The present study was designed to investigate the perception of unilateral cleft lip (UCL) repair scar using an image of an adolescent and eye-tracking technology.
Material and methods: Frontal and oblique views of an image of an adolescent with a unilateral upper lip scar result of a corrective surgery. Eighty-five laypeople respondents were divided into three groups: Group A (15-44 years of age); Group B (45-59 years of age); and Group C (≥ 60 years of age). Gaze tracking was carried out to assess the location on the image of greatest fixation, to create dot maps and to follow the trajectory of the gaze. Respondents also assessed six attention questionnaires. The answers and assessment of the VAS were compared. P-values <0.05 were considered significant in the analyses.
Results: The central focus of the visualization was concentrated on the upper lip and the region of the nostril, followed by the eyes. Time until 1st fixation upon right lip and mouth showed differences with regard to different images. Images of the model shown in various guises including smiling or not, in a frontal or oblique views showed significant differences in VAS scoring (p<0.001).
Conclusion: The presence of a scar from the UCL repair in an adolescent was noted in the foreground by laypeople. The scar was associated with a lower degree of attractiveness, happiness, and intelligence, as well as with shyness and sympathy, although a visible scar did not influence the perception of "good hygiene habits".
