摘要
Objective. To compare live versus delayed feedback on trainee performance of bilobe flaps using 3-dimensional (3D)-printed facial simulators and determine whether these effects are sustained on repeat performance.Study Design. Cohort study.Setting. University of Arkansas for Medical Sciences.Methods. 3D-printed facial models with a nasal ala defect were provided to 18 subjects. Subjects were stratified and randomized based on their training level into 1 of 3 groups corresponding to live feedback (Group 1), delayed feedback (Group 2), and no feedback (Group 3). Subjects performed a bilobe flap following a structured lecture. Four weeks later, subjects independently repeated the exercise on the contralateral ala. Likert surveys were used to assess subjective parameters. Objective grading was performed by a plastic surgeon, which included a point system and score for the overall appearance.Results. Following exercise 1, Group 1 reported a significant improvement in knowledge (P < .001), which was sustained after exercise 2 (P < .001); Group 2 reported a significant improvement after exercise 1 (P = .03) but was not sustained (P = .435). After the second exercise, Group 1 and Group 2 improved their confidence in bilobed repair (P = .001 and P = .003, respectively), but this was greater for Group 1. Group 1 showed a significant improvement in their design time following exercise 2 (P = .007). There were no significant differences between groups on total time for repair, total score, and appearance.Conclusion. 3D-printed models are valuable in teaching the bilobe flap for nasal defects, with live feedback providing the greatest level of improvement in self-reported knowledge and confidence.
