SlicerOrbitSurgerySim: An Open-Source Platform for Virtual Registration and Quantitative Comparison of Preformed...

Area of Science:

• Medical device engineering
• Computer-aided surgery
• Biomedical informatics

Background:

• Poor orbital implant adaptation leads to significant postoperative complications and revision surgeries.
• Preformed orbital plates offer cost and time efficiencies over customized implants but lack standardized comparison tools.
• Quantitative metrics for comparing plate fit across different vendors, sizes, and patient anatomies are currently unavailable to surgeons.

Purpose of the Study:

• To develop an open-source software tool for quantitative evaluation and comparison of preformed orbital plates.
• To enable patient-specific virtual planning and population-level analysis of orbital plate adaptability.
• To improve preoperative decision-making and reduce intraoperative modifications in orbital reconstruction.

Main Methods:

• Development of SlicerOrbitSurgerySim, an open-source extension for 3D Slicer.
• Implementation of interactive virtual registration and evaluation of multiple preformed orbital plates.
• Generation of quantitative plate-to-orbit distance metrics and visualization tools.

Main Results:

• SlicerOrbitSurgerySim provides reproducible quantitative metrics for plate-to-orbit distance.
• The software facilitates objective comparison of implant designs and placement strategies.
• The tool supports both patient-specific surgical planning and large-scale statistical analysis.

Conclusions:

• The developed software enhances preoperative planning for orbital reconstruction using preformed plates.
• Objective comparison of implant adaptability can lead to reduced intraoperative plate modifications.
• The open-source tool promotes collaborative research, surgical education, and improved patient outcomes.
