Multiple subpial transection (MST) offers a promising surgical option for drug-resistant epilepsy in critical brain areas. This technique showed significant seizure reduction in most patients with minimal neurological deficits.

Area of Science:

  • Neurosurgery
  • Epileptology
  • Clinical Neurology

Background:

  • Pharmaco-resistant partial epilepsy often necessitates surgical intervention.
  • Identifying effective treatments for epilepsy in highly functional cortical areas remains a challenge.
  • Multiple subpial transection (MST) is a surgical technique explored for epilepsy management.

Observation:

  • Seven cases of pure MST, without cortical resection, were performed for drug-resistant partial epilepsy.
  • The surgical technique followed the method described by Morrell.
  • Patient follow-up ranged from 1 to 4 years.

Findings:

  • MST resulted in no significant neurological handicap; only two patients had transient deficits with full recovery within a month.
  • Five patients experienced substantial seizure frequency reduction (40-100%).

  • One patient with complex partial seizures transitioned to simple partial seizures post-operatively.

    • Implications:

    • Pure MST appears to be an adequate procedure for selected cases of epilepsy in eloquent cortex.
    • Potential failures may stem from limited transection areas or inaccurate focus delimitation.
    • Further studies are needed to establish statistically significant outcomes for MST in epilepsy surgery.
