Gaze Patterns of Normal and Microtia Ears Pre- and Post-Reconstruction. The Laryngoscope Losorelli, S., Chang, J. K., Chang, K. W., Most, S. P., Truong, M. T. 2024

Abstract

To understand attentional preferences for normal and microtia ears.Eye-tracking technology was used to characterize gaze preferences. A total of 71 participants viewed images of 5 patients with unilateral microtia. Profile images of patient faces and isolated ears including normal, microtia, and post-reconstruction microtia ears were shown. Total time of fixation in predefined areas of interest (AOI) was measured. Inferential statistics were used to assess significance of fixation differences between AOIs within and between facial or auricular features.The ear received most visual attention in lateral view of the face (1.91?s, 1.66-2.16?s) [mean, 95% CI], followed by features of the "central triangle"-the eyes (1.26?s, 1.06-1.46), nose (0.48?s, 0.38-0.58), and mouth (0.15?s, 0.15-0.20). In frontal view, microtia ears received less attention following surgical reconstruction (0.74?s vs. 0.4?s, p?
