Summary
A novel method integrates a stereotactic frame with frameless stereotactic systems for improved instrument targeting and trajectory planning. This approach enhances probe stability and accuracy in neurosurgical procedures.
Area of Science:
- Neurosurgery
- Medical Devices
- Surgical Navigation
Background:
- Improving targeting and trajectory planning in stereotactic surgery.
- Developing a secure probe-holding system for frameless stereotactic procedures.
Purpose of the Study:
- To devise a simple method integrating a stereotactic frame as an instrument holder for frameless stereotactic systems.
- To enhance targeting capability, trajectory planning, and probe-holding security.
Main Methods:
- Utilized a modified stereotactic frame with a BrainLab vector vision neuronavigation system.
- Attached the reference array to the stereotactic head-holder and placed the frameless system's pointer in the frame's probe-holder.
- Implemented an offset correction on the monitor to align the frame's arc center with the probe line tip, positioning the arc center on the target using the frame's coordinate adjuster.
Main Results:
- Achieved accuracy within 2.5 mm in all three planes for depth electrode placement.
- Facilitated easy access to the temporal horn in three patients.
- Successfully performed seven procedures for depth electrode insertion.
Conclusions:
- Presents a simple method for using a stereotactic frame to improve coordinate and trajectory adjustments.
- Offers a superior method for stabilizing the pointer and probe-holder in frameless stereotactic procedures.
