In Vitro Comparative Study Between Conventional and Computer-Assisted Surgery Methods for Planning and Resection of...

Area of Science:

• Surgical Oncology
• Medical Imaging
• Biomedical Engineering

Background:

• Accurate surgical planning is crucial for effective tumor resection.
• Traditional methods rely on 2D imaging and manual measurements, which can have limitations.
• Advancements in 3D imaging and navigation technologies offer potential improvements in surgical precision.

Purpose of the Study:

• To conduct an in vitro comparative study of different surgical planning and execution methods for sarcoma resection.
• To evaluate the efficacy of 2D versus 3D planning, with and without navigation assistance.

Main Methods:

• Comparative in vitro study.
• Method 1: 2D digital image planning and freehand execution (ruler and caliper).
• Method 2: 3D planning and freehand execution (ruler and caliper).
• Method 3: 3D planning and execution guided with surgical navigation.

Main Results:

• 3D planning and navigated procedures demonstrated potential advantages over 2D methods.
• Freehand techniques, even with 3D planning, may be less precise than navigated approaches.
• Navigation-assisted 3D planning offers enhanced accuracy in simulated sarcoma resection.

Conclusions:

• 3D planning combined with surgical navigation may lead to more precise sarcoma resection.
• Navigated 3D planning represents a promising advancement in surgical oncology.
• Further in vivo studies are warranted to confirm these in vitro findings.
