Summary
Three-dimensional (3D) reconstruction guided brain lesion resection using adjacent landmarks offers precise surgical planning and execution. This technique enhances neurosurgical safety and efficiency, potentially reducing costs and accelerating surgeon training.
Area of Science:
- Neurosurgery
- Medical Imaging
- Surgical Technology
Background:
- Brain lesion resection requires precise surgical navigation.
- Traditional methods may have limitations in complex cases.
- Three-dimensional (3D) reconstruction offers advanced visualization capabilities.
Purpose of the Study:
- To evaluate the efficacy of 3D reconstruction-guided brain lesion resection.
- To assess the use of adjacent anatomical landmarks for surgical planning.
- To determine the impact on surgical precision and patient outcomes.
Main Methods:
- 13 patients with brain lesions underwent 3D reconstruction-guided microsurgery.
- Preoperative planning involved fusing multimodal imaging using 3D Slicer.
- Surgical trajectories were guided by adjacent anatomical structures like sulci, gyri, vessels, and nerves.
Main Results:
- Accurate intraoperative lesion localization was achieved via 3D reconstruction.
- Complete resection was successful in most cases, with one exception.
- Most patients experienced no new neurological deficits; others had transient or resolved deficits.
Conclusions:
- 3D reconstruction-guided resection optimizes surgical planning and execution.
- This approach enhances neurosurgical quality and safety.
- It offers benefits in cost reduction and surgeon training acceleration.
