Summary
Building 3D CT skull models is effective for preoperative planning but requires standardization and quality control. Surgeon involvement and phantom models can improve reliability before clinical routine adoption.
Area of Science:
- Medical Imaging
- Surgical Planning
- Biomedical Engineering
Background:
- Three-dimensional (3D) model building offers potential for preoperative planning.
- Current methods face challenges related to failure points and complexity.
- Standardization and quality control are crucial for reliable 3D model application.
Purpose of the Study:
- To evaluate the clinical efficiency and readiness of 3D CT skull model building for preoperative planning.
- To identify critical factors for successful implementation and areas needing improvement.
Main Methods:
- Clinical evaluation of 3D CT skull model building processes.
- Analysis of potential failure points in data acquisition and manufacturing (stereolithography vs. milling).
- Assessment of surgeon involvement in data analysis and segmentation.
Main Results:
- 3D model building is an excellent method for 3D preoperative planning.
- Stereolithography is more complex than milling, necessitating stringent quality control.
- Surgeon involvement in essential steps is a key factor for success.
- Phantom models may mitigate risks.
Conclusions:
- 3D CT skull model building is clinically efficient and mature for use.
- It cannot yet be considered clinical routine due to potential failures.
- Urgent need for quality assurance and standardization in data acquisition and manufacturing.
