This study examines the success rates of temporal and extra-lesional hemispheric callosotomy in treating epilepsy. Key findings reveal that 68% of patients became seizure-free post-surgery, while 45% showed improved seizure control. The overall improvement rates were notable, with a total of 100% reporting some level of change. The research highlights the effectiveness of these surgical interventions, providing significant insights into epilepsy treatment. Reference: Engel, J. NEJM, Vol. 334, 1996, 647-653.
