Summary
Three-dimensional (3D) modeling enhances pituitary adenoma surgery by providing surgeons with superior spatial orientation. This advanced 3D surgical planning improves confidence and safety during complex tumor removal procedures.
Area of Science:
- Neurosurgery
- Medical Imaging
- Surgical Planning
Background:
- Pituitary adenoma surgery requires precise anatomical understanding.
- Conventional 2D imaging may limit intraoperative spatial awareness.
Purpose of the Study:
- To assess the feasibility of 3D surgical planning for pituitary adenoma removal.
- To evaluate the utility of 3D models in routine surgical practice.
Main Methods:
- Computed tomography (CT) and magnetic resonance imaging (MRI) data from 40 patients were utilized.
- Three-dimensional (3D) models were constructed using open-source software (3D Slicer) on a personal computer.
- 3D models were employed for both preoperative planning and intraoperative guidance.
Main Results:
- 3D modeling provided enhanced orientation to the surgical field compared to 2D images.
- Surgeons reported increased confidence in navigating critical structures during tumor evacuation.
- The 3D model served as an effective intraoperative 'road map'.
Conclusions:
- Preoperative 3D modeling of pituitary adenomas is feasible and beneficial.
- Routine adoption of 3D modeling improves surgical orientation and confidence.
- This technique enhances patient safety in pituitary surgery.
