Summary
A new Standardized Electrode Nomenclature for SEEG Applications system offers clear, unique labels for stereoelectroencephalography (SEEG) electrodes. This system improves communication and collaboration in epilepsy research and clinical practice.
Area of Science:
- Neurology
- Neurosurgery
- Medical Device Technology
Background:
- Stereoelectroencephalography (SEEG) is a crucial invasive method for seizure localization in medically refractory epilepsy.
- Current SEEG electrode naming lacks standardization, leading to confusion and hindering collaboration among clinical and research teams.
Purpose of the Study:
- To introduce a novel, standardized nomenclature for SEEG electrodes.
- To enhance clarity, uniqueness, and informativeness in electrode labeling for SEEG procedures.
Main Methods:
- Development of the Standardized Electrode Nomenclature for SEEG Applications (SENA) system.
- Evaluation of inter-rater agreement using 10 retrospective SEEG cases (136 electrodes).
- Prospective implementation and validation in 40 consecutive SEEG patients.
Main Results:
- The SENA system generated unique and informative electrode names for all implemented cases.
- High inter-rater agreement (97.5%) was achieved among neurosurgeons and neurologists.
- The nomenclature facilitated implantation design, data interpretation, and treatment planning.
Conclusions:
- The SENA system provides a simple, reproducible, and informative method for SEEG electrode identification.
- Standardized nomenclature improves information sharing in clinical and research settings.
- Widespread adoption of this system can enhance communication and collaboration in epilepsy management.
