Summary
Facial nerve injury during mastoid surgery is a risk. This study introduces a model using EMG signals to visualize the nerve in preoperative images, aiding surgeons in nerve preservation.
Area of Science:
- Neurosurgery
- Medical Imaging
- Biomedical Engineering
Background:
- Mastoid bone removal poses a risk of facial nerve injury.
- Accurate intraoperative nerve localization is crucial for surgical safety.
Purpose of the Study:
- To develop a model for visualizing the facial nerve in preoperative image data.
- To integrate intraoperative EMG signals for enhanced nerve detection.
- To assist surgeons in locating and preserving the facial nerve during mastoid procedures.
Main Methods:
- Utilizing intraoperatively gained EMG signals.
- Developing a model to spatially relate EMG signals to patient image data.
- Implementing real-time nerve visualization during surgical navigation.
Main Results:
- A model was proposed to integrate EMG signals with preoperative imaging.
- The model allows for spatial correlation of nerve signals to patient data.
- The system provides a visualized nerve course during navigation.
Conclusions:
- The proposed model enables nerve visualization in preoperative images using EMG signals.
- This neuro monitor assists surgeons in identifying and protecting the facial nerve.
- Real-time visualization improves surgical assessment and nerve preservation during mastoid surgery.
