Summary
This study introduces a reproducible 3D-printing method for accurate orbital volume (OV) measurement. The developed technique offers a standardized approach for in vivo OV assessment, enhancing anatomical studies.
Area of Science:
- Anatomical imaging and measurement techniques
- Biomedical engineering and 3D printing applications
- Craniomaxillofacial surgery and research
Background:
- Accurate orbital volume (OV) measurement is crucial for diagnosing and managing various orbital conditions.
- Traditional methods for OV measurement can be time-consuming and lack reproducibility.
- Advancements in 3D printing offer potential for developing more precise anatomical measurement tools.
Purpose of the Study:
- To develop and validate a reproducible method for in vivo orbital volume (OV) measurement using 3D printing technology.
- To compare the accuracy and reliability of the 3D-printing method against conventional techniques.
Main Methods:
- Twelve dry human skulls were utilized, with CT scan data converted to STL format for 3D printing.
- Two 3D-printing approaches were tested: sealing bone openings post-printing (3D-Orb-1) and in silico sealing (3D-Orb-2).
- Orbital volumes were measured and compared to a control group using the conventional water-filling method (Anat-Orb).
Main Results:
- The 3D-printing methods yielded mean orbital volumes comparable to the control group.
- Excellent intra-rater (ICC > 0.994) and inter-observer (ICC: 0.969) agreement were observed for the 3D-printing methods.
- The 3D-Orb-1 method showed excellent agreement with the control (ICC: 0.972), while 3D-Orb-2 showed moderate agreement (ICC: 0.855).
Conclusions:
- The developed 3D-printing method provides a standardized and reproducible approach for orbital volume measurement.
- This technique holds promise for improving the accuracy and consistency of in vivo OV assessments in anatomical and clinical research.
- Further refinement of the in silico sealing method may enhance its accuracy for OV quantification.
