Abstract
Objective: To propose a model of laryngoplastic injection simulator manufactured using 3D printing and other low-cost materials. Methods: This is a descriptive experimental study. The modeling of osteocartilaginous structures of the larynx was made from images acquired through radiography of the neck in the lateral and anteroposterior views of a young adult male. 3D printer model FDM (Fused Deposition Modeling) with polylactic acid plastic filament was used to print the osteocartilagenous structures of the larynx. The vocal folds were represented using glove fingers. Results: The laryngeal framework was modeled in such a way that the vocal folds fit into the glottis. The base and the support structure were made from medium density synthetic wood fiber board; the laryngeal framework being fixed to it through a magnet system. The simulation occurs through the injection of material inside the vocal folds, with an increase in their volume being observed. Conclusion: A high degree of fidelity was observed in the anatomical representation and tactile properties of the osteocartilaginous framework, which, in addition to the high reproducibility and low cost, makes it possible to integrate residency services into the daily practice as a new teaching methodology
