Development and validation of a septoplasty training model using 3-dimensional printing technology.

Area of Science:

• Surgical Simulation
• Medical Device Development
• 3D Printing in Medicine

Background:

• Alternative training modalities are crucial for enhancing surgical skills in septoplasty.
• Three-dimensional (3D) printing offers a powerful platform for surgical training.
• Developing realistic simulators can improve trainee proficiency in complex procedures.

Purpose of the Study:

• To detail the creation of a novel 3D printed septoplasty training model.
• To evaluate the face and content validity of the developed septoplasty simulator.
• To provide evidence of the model's ability to discriminate between varying levels of surgical expertise.

Main Methods:

• A 3D printed model was created using patient imaging data of nasal septal deviation.
• Materials were selected to mimic the mechanical properties of human tissues.
• Expert and resident surgeons performed simulated septoplasties, with performance metrics analyzed.

Main Results:

• The 3D printed model achieved high scores for anatomical correctness and realism.
• A significant majority of residents expressed a desire for curriculum integration.
• The model demonstrated significant differences in performance metrics between surgeon groups.

Conclusions:

• This study presents a unique 3D printed simulator for septoplasty training.
• The model's design incorporates multiple material consistencies for enhanced realism.
• Findings support the validity and utility of this novel surgical training tool.
