Evaluation of a high-fidelity cleft alveolar bone graft simulator

Abstract

IntroductionCleft alveolar bone graft surgery is technically challenging to perform as well as difficult to learn and teach. A high-fidelity cleft alveolar bone graft simulator was previously developed. However, further evaluation of the simulator is necessary to assess its efficacy. MethodsTwo cleft simulation workshops were conducted in which participants were led through a simulated cleft alveolar bone graft. The first simulation workshop involved six plastic surgery trainees. The second workshop involved 43 practicing cleft surgeons. The participants were provided with a Likert-type questionnaire assessing the simulators’ features, realism, and value as a training tool. The change in self-reported confidence was assessed by providing each participant with a pre- and post-simulation confidence questionnaire. ResultsThere was overall agreement in the realism of the simulators’ features (average score of 4.67 and 3.80 out of 5 for the trainees and surgeons, respectively). There was overall agreement to strong agreement in the simulators value as a training tool (average score of 5 and 4.43 out of 5 for the trainees and surgeons, respectively). The self-reported confidence increased for all questionnaire items for both the trainees and surgeons. This was significant (p < 0.05) for five out of eight and all questionnaire items for the trainees and surgeons, respectively. The magnitude of the confidence increase was generally greater for less experienced participants. ConclusionThe cleft alveolar bone graft simulator was found to be realistic and valuable as a training platform. Use of the simulator improved self-reported confidence in cleft alveolar bone graft surgery.
