Summary
Medical students show attention biases when assessing children with unicoronal craniosynostosis (UCS). Their gaze patterns reveal potential educational gaps in craniofacial assessment, highlighting the need for targeted training.
Area of Science:
- Medical education
- Ophthalmology
- Pediatric surgery
Background:
- Unicoronal craniosynostosis (UCS) is a congenital condition requiring early diagnosis.
- Medical students' ability to accurately assess craniofacial anomalies is crucial for timely intervention.
- Objective assessment of diagnostic skills in medical trainees is essential for identifying educational needs.
Purpose of the Study:
- To objectively identify medical students' gaze patterns when assessing children with and without unicoronal craniosynostosis (UCS).
- To pinpoint potential diagnostic and educational gaps in medical students' assessment of UCS.
- To evaluate attentional biases in medical students' evaluation of craniofacial structures.
Main Methods:
- Utilized eye-tracking technology to record medical students' gaze patterns while viewing images of children with/without UCS.
- Quantified cumulative dwell times on specific facial interest areas (forehead, brow, eyes, nose, lower face, mouth, ears).
- Compared dwell times between images of children with UCS and control images.
Main Results:
- Students spent significantly more time on the brow and less on the nose when viewing UCS images.
- Increased dwell time was observed on the forehead contralateral to the fused suture in UCS images.
- Attentional biases were noted, with focus shifting in control images as well, indicating selective attention.
Conclusions:
- Medical students exhibit significant attentional biases when assessing children with UCS.
- Current assessment practices may overlook key asymmetries, indicating potential educational deficits.
- Targeted training in craniofacial assessment is necessary to improve diagnostic accuracy for UCS.
