INTRODUCTION: Micrognathia, a component of Robin Sequence, can cause glossoptosis, failure of palatal fusion, and critical obstruction of the airway. Mandibular distraction osteogenesis (MDO) is at times offered to anteriorly translate the mandible and tongue, relieving airway obstruction. MDO is an intricate reconstructive procedure that may be ideal for teaching using a high-fidelity educational simulator, allowing early hands-on experience in a zero-risk environment.
OBJECTIVES: To design a novel, low-cost, high-fidelity neonatal MDO simulator that can be used for trainee education and refinement of surgical technique.
METHODS: A novel MDO simulator was developed using additive manufacturing techniques. Three experts in MDO surgery completed a 20-item survey, rating the simulator's physical attributes, the realism of experience, the simulator's value, its relevance to practice and the surgeon's ability to perform tasks on a 4-point Likert scale.
RESULTS: Computer Aided Design (CAD) and 3D printing allowed for the production of a realistic surgical simulator that emulates important aspects of MDO surgery. This preliminary evaluation indicated adequate means across the five domains relevant to the simulator's fidelity and usability (M = 3.33 to 3.75) out of a maximum of 4 points. Lowest rated items were consistent with expert comments allowing future refinement on subsequent iterations. Consumable material costs per model were $9.39 USD.
CONCLUSIONS: The MDO model demonstrated adequate fidelity and holds promise as a skill-development tool for surgeons in training. Further studies are planned to determine its utility as a training and assessment tool.
