Abstract

Objective: The purpose of this study is to determine children's perception of secondary cleft lip deformity (SCLD) using objective eye tracking technology and subjective responses on a survey to understand pediatric perceptions of facial scarring.

Design: Cross-sectional study of participants aged 5-17 years old.

Methods: Participants viewed images of children's faces with an eye tracking device. Sixteen images were displayed, 12 with unilateral SCLD and four with no facial scarring. Eye tracking data were obtained. Gaze samples were analyzed for areas of interest (AOIs). Immediately after viewing each image, participants answered two survey questions relating to facial asymmetry attitude toward the child pictured. For analysis, participants were divided into age groups.

Results: A total of 259 participants were enrolled (42.5% female). Mean age was 10.5 years and 78% identified as White. In all age groups, total fixation time was greater for SCLD compared to control images. Early elementary age children spent significantly less time assessing the nose AOI compared to other groups, and also spent the least total fixation time and had the lowest visit count on all AOIs. Subjective survey questions showed similar trends with elementary age not noticing facial asymmetry compared to older age groups.

Conclusion: This study demonstrates the successful use of eye tracking technology in children as young as 5 years old. This study suggests that SCLD is perceived as less noticeable in elementary age children and becomes more noticeable to older groups. Understanding peer perception on SCLD from this study may impact decision on revision surgery for SCLD.
