3D Glenoid Fossa Reconstruction and Analysis
Corresponding Organization : University of Southern Denmark
Variable analysis
- Semi-automatic segmentation of pre- and postoperative crania
- Registration of postoperative CBCT scan to preoperative CBCT scan by VBR using the anterior cranial base, zygomatic arches, and forehead as the volume of interest
- Manual tracing of a curve engulfing the preoperative glenoid fossa, which was automatically attracted and attached to the surface of the postoperative skull, defining the postoperative glenoid fossa
- Three-dimensional assessment of glenoid fossa changes
- Representation of glenoid fossa surface discrepancies by color-coded distance maps
- Quantification of glenoid fossa surface discrepancies by the root mean square (RMS) surface distance of the total glenoid fossa and the four defined fossa sub-regions
- The anterior cranial base, zygomatic arches, and forehead as the volume of interest unaffected by the surgery
- None specified

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
