Incorporating Cleft Lip Simulation Into a "Bootcamp-Style" Curriculum.

INTRODUCTION: The traditions of surgical education have changed little over the years. However, the increasing focus on patient safety and duty hour restrictions mandates that residents start developing complex skill sets earlier to ensure they graduate with procedural competency. Surgical training is poised to exploit high-fidelity simulation technology to mitigate these pressures. METHODS: By revisiting principles of adult learning theory, the authors created a "bootcamp-style" cleft lip curriculum that sought to (1) maximize educational impact and (2) pilot a high-fidelity procedural trainer permitting resident operative autonomy as part of that curriculum. Trainees participated in small group educational sessions comprised of a standard cleft didactic lecture, augmented by instructional video. Participants immediately processed knowledge from the lecture/video by "operating" on the simulator, allowing opportunities for questions and self-reflection, completing the learning cycle. A self-assessment survey was taken before and after each component of the session, including a self-confidence survey to conclude the session. Anthropometric measures of lip/nasal symmetry were assessed. RESULTS: Sixteen trainees participated in the program. Little increase in self-assessed knowledge/skill was seen after the lecture, but significant increases in most aspects of cleft lip repair were seen after simulation. The greatest increase in self-assessment was seen for the program as a whole, with significant differences across all aspects of the self-assessment. Higher levels of training were associated with both higher self-assessment scores and better lip symmetry. Regardless of level of training, all participants strongly agreed that simulation helped them actively engage in learning and should be a required aspect of training, whereas 94% (n = 15) thought simulation was much more effective than standard preparation alone. CONCLUSIONS: This pilot curriculum illustrates a mechanism to incorporate lessons from adult learning theory into plastic surgery training using a high-fidelity simulator for deliberate practice of cleft lip repair. Further evaluation is warranted to determine whether this didactic model can accelerate the acquisition of the complex skill set required for cleft lip repair and other surgical procedures.

Simulation model for transcervical laryngeal injection providing real-time feedback.

OBJECTIVE: This study aimed to develop and evaluate a model for teaching transcervical laryngeal injections. METHODS: A 3-dimensional printer was used to create a laryngotracheal framework based on de-identified computed tomography images of a human larynx. The arytenoid cartilages and intrinsic laryngeal musculature were created in silicone from clay casts and thermoplastic molds. The thyroarytenoid (TA) muscle was created with electrically conductive silicone using metallic filaments embedded in silicone. Wires connected TA muscles to an electrical circuit incorporating a cell phone and speaker. A needle electrode completed the circuit when inserted in the TA during simulated injection, providing real-time feedback of successful needle placement by producing an audible sound. Face validation by the senior author confirmed appropriate tactile feedback and anatomical realism. Otolaryngologists pilot tested the model and completed presimulation and postsimulation questionnaires. RESULTS: The high-fidelity simulation model provided tactile and audio feedback during needle placement, simulating transcervical vocal fold injections. Otolaryngology residents demonstrated higher comfort levels with transcervical thyroarytenoid injection on postsimulation questionnaires. CONCLUSION: This is the first study to describe a simulator for developing transcervical vocal fold injection skills. The model provides real-time tactile and auditory feedback that aids in skill acquisition. Otolaryngologists reported increased confidence with transcervical injection after using the simulator.
