A novel functional hemispherectomy technique offers reduced invasiveness and similar immediate seizure relief compared to traditional methods. Further long-term studies are needed to confirm lasting efficacy and safety.

Area of Science:

  • Neurosurgery
  • Epilepsy Surgery
  • Neurology

Background:

  • Functional hemispherectomy is a treatment for severe epilepsy.
  • Existing techniques carry significant risks and invasiveness.

Purpose of the Study:

  • To introduce and describe a novel, less invasive functional hemispherectomy technique.
  • To evaluate the initial surgical outcomes and seizure control in patients undergoing this new procedure.

Main Methods:

  • The technique involves a smaller craniotomy, hippocampectomy, and deafferentation of white matter via transcortical transventricular or sylvian keyhole approaches.
  • It includes transventricular callosotomy, preserving some insular and suprainsular cortex.

Main Results:

  • The procedure was performed on 13 patients, with shorter operation times and less blood loss compared to other methods.
  • Immediate seizure relief was comparable to traditional functional hemispherectomy.

    • Conclusions:

    • This alternative functional hemispherectomy technique appears safe and effective for immediate seizure control.
    • Long-term seizure control and complication data require further investigation with extended follow-up.
