Teaching Pediatric Straddle Injury Repair with Use of a 3D Printed Model

Abstract

Study objective: To determine the utility of a 3D vulvar model for teaching pediatric straddle injury repair.

Design: Prospective study.

Setting: Two academic hospitals.

Participants: Twenty obstetrics and gynecology residents INTERVENTIONS AND MAIN OUTCOME MEASURES: Knowledge score on the basis of a 7-question pre/post test. Likert scale questions evaluated the 3D model as a teaching tool.

Results: Twenty residents participated; 2 (10%) had ever repaired a straddle injury. Knowledge scores increased after model use and didactic session from 3.05 of possible 7 to 6.35; P = .001. Only 2/20 (10%) residents "agreed" or "strongly agreed" with the statement, "I am comfortable repairing a straddle injury" before the intervention, compared with 19/20 (95%) afterward (P < .001). Of 20 residents, 19 (95%) believed that it simulated surgical experience "very well" or "well."

Conclusion: The use of a 3D pediatric vulvar model can simulate surgical experience and can be an effective teaching tool when combined with a didactic session on pediatric straddle injury.
