Design and Printing of a Low-Cost 3D Printed Nasal Osteotomy Training Model: Feasibility Study
ABSTRACT
Background:
Nasal osteotomy is a commonly performed procedure during rhinoplasty for both functional and cosmetic reasons. Teaching and learning this procedure proves difficult due to the reliance on nuanced tactile feedback. For surgical simulation, trainees are traditionally limited to cadaveric bone which can be costly and difficult to obtain.
Objective:
This study aimed to design and print a low-cost midface model for nasal osteotomy simulation.
Methods:
A 3D reconstruction of the midface was modified using a free open-source design software. The lower nasal cartilage was smoothed and support rods were added to hold fragments generated from simulation in place. Several models with various infill densities were printed using a desktop 3D printer to determine which best mimicked human facial bone.
Results:
A midface simulation set was designed using a desktop 3D printer, polylactic acid filament, and easily accessible tools. A nasal osteotomy procedure was successfully simulated using the model.
Conclusions:
3D printing is a low-cost, accessible technology that can be used to create simulation models. With growing restrictions on trainee duty hours, the simulation set can be used by programs to augment surgical training.
