Area of Science:

Neurosurgery
Medical Technology

Background:

Awake craniotomy is a complex procedure requiring precise surgical navigation.
Traditional navigation systems often rely on rigid head fixation, which can cause discomfort and interfere with monitoring.
Electromagnetic navigation offers a potential alternative to improve patient experience and surgical workflow.

Purpose of the Study:

To evaluate the institutional experience with an electromagnetic navigation system for awake craniotomy without rigid head fixation.
To assess the accuracy, safety, and patient comfort associated with this technique.

Main Methods:

Utilized the StealthStation® S7 AxiEM™ electromagnetic navigation system.
Performed detailed preoperative evaluations, patient education, and contrast-enhanced MRI.
Employed a non-invasive patient tracker and monitored conscious sedation.
Used the AxiEM Navigation Pointer for intraoperative guidance.

Main Results:

The electromagnetic navigation system demonstrated accuracy comparable to optical navigation.
The technique eliminated the need for rigid head fixation, enhancing patient comfort.
No interference was observed with intraoperative neurophysiological monitoring or surgical instruments.
The system proved to be an effective adjunctive technique for awake surgery.

Conclusions:

Electromagnetic neuronavigation without rigid head fixation is accurate and safe for awake craniotomy.
This method significantly improves patient comfort compared to traditional fixation methods.
It is recommended as a valuable tool for enhancing awake surgery procedures.
