A novel three-dimensional-printed paranasal sinus-skull base anatomical model.

Area of Science:

• Anatomical modeling
• Medical device development
• 3D printing applications

Background:

• Accurate anatomical understanding of the paranasal sinus and skull base is crucial for surgical procedures.
• Existing visualization methods may lack detailed three-dimensional (3D) spatial information.

Purpose of the Study:

• To develop a novel, precision 3D-printed anatomical model of the paranasal sinus-skull base.
• To evaluate the accuracy, utility, and educational value of this 3D model.

Main Methods:

• Computed tomography (CT) data of the paranasal sinus were used to create a 3D digital model.
• The digital model was sliced and printed in 1:1 scale using a commercial desktop 3D printer.
• Nine senior physicians assessed the model's accuracy and educational value using a Likert scale.

Main Results:

• A life-like 3D paranasal sinus-skull base model was successfully printed, clearly displaying internal spatial details.
• Physicians confirmed the model's anatomical accuracy and noted its enhanced 3D spatial visualization compared to CT scans.
• The model was deemed highly valuable for anatomy teaching and complex paranasal sinus-skull base surgeries, with a low material cost of $3.

Conclusions:

• The 3D printed paranasal sinus-skull base model serves as an effective tool for anatomical study.
• This novel 3D model enhances resident training, pre-surgical education, and surgical planning for paranasal sinus procedures.
