Complete Corpus Callosotomy for Refractory Epilepsy in Children

Area of Science:

• Neurosurgery
• Epilepsy Surgery
• Neurology

Background:

• Corpus callosotomy severs interhemispheric connections to prevent seizure generalization.
• It is indicated for intractable, debilitating generalized epilepsy resistant to medication and resection.
• The procedure has a long history of safety and effectiveness in selected patients.

Observation:

• A case of a 4-year-old boy with Lennox-Gastaut syndrome undergoing open single-stage complete callosotomy is presented.
• The video demonstrates a microscope-assisted interhemispheric approach with stereotactic navigation.
• Key surgical steps, including dissection and callosotomy, are highlighted with anatomical landmarks.

Findings:

• Total corpus callosotomy shows superior seizure reduction compared to partial callosotomy.
• Significant reduction in drop attacks is observed with total callosotomy.
• A transient risk of disconnection syndromes exists with total callosotomy, resolving within six weeks.

Implications:

• Corpus callosotomy can improve daily function, psychosocial adjustment, and family satisfaction, particularly in children.
• The described surgical technique is adaptable for resource-constrained settings.
• This work provides a foundation for advanced techniques like endoscopic or laser-guided callosotomies.
