Engel Classification
A standardized outcome scale for measuring seizure control after epilepsy surgery.
Full Definition
The Engel Classification is a widely used outcome assessment tool developed by Jerome Engel Jr. to standardize the reporting of surgical results in epilepsy patients. The classification system ranges from Class I (seizure-free or auras only) to Class IV (no significant improvement), with subdivisions providing more detailed outcome descriptions. This classification has become the gold standard for evaluating epilepsy surgery effectiveness and is essential for comparing outcomes across different surgical centers and techniques. It helps clinicians and researchers communicate surgical success rates in a standardized manner.
Usage
Usage note: Should not be confused with the newer ILAE outcome classification system.
