Expert otolaryngologists demonstrate more comprehensive gaze patterns during nasal analysis than trainees. Eye-tracking reveals differences in approach, not quantitative fixation metrics, suggesting potential for targeted training tools.
Area of Science:
- Otolaryngology
- Medical Education
- Ophthalmology
Background:
- Nasal analysis is a critical skill for otolaryngology trainees.
- Competency in nasal analysis is assessed in board examinations.
- Objective measurement of nasal analysis skills is needed.
Purpose of the Study:
- To compare the gaze patterns of experts and trainees during nasal analysis.
- To utilize eye-tracking software to quantify visual focus during nasal examinations.
- To identify differences in visual search strategies between expert and trainee otolaryngologists.
Main Methods:
- 27 participants of varying training levels were included.
- Participants viewed standardized photographs of faces for nasal analysis.
- Eye-tracking data, including heat maps and fixation metrics, were collected and analyzed.
Main Results:
- Qualitative analysis showed experts employed more organized and comprehensive gaze patterns.
- Quantitative eye-tracking metrics (time to first fixation, duration, number of fixations) were similar between experts and trainees.
- Gaze patterns differed, but fixation behaviors did not significantly vary between groups.
Conclusions:
- Eye-tracking reveals experts exhibit more thorough visual exploration during nasal analysis.
- Despite similar quantitative fixation data, qualitative gaze differences highlight expert efficiency.
- Findings suggest potential for developing eye-tracking-based learning tools for nasal analysis training.
