Endoscopic removal of hypothalamic hamartomas offers seizure control and behavioral improvement. This minimally invasive surgery can be effective in selected patients, though careful case selection is crucial for optimal outcomes.

Area of Science:

  • Neurosurgery
  • Neurology
  • Pediatric Neurosurgery

Background:

  • Hypothalamic hamartomas are associated with seizures and behavioral issues.
  • Surgical intervention, including removal or disconnection, shows promise for seizure control.

Purpose of the Study:

  • To report the experiences and early outcomes of endoscopic removal of hypothalamic hamartomas.
  • To evaluate the efficacy and safety of this minimally invasive approach.

Main Methods:

  • Prospective review of 44 patients undergoing endoscopic resection.
  • Utilized frameless stereotaxis and a micromanipulator for precise tumor removal.

Main Results:

  • Complete resection achieved in 14 patients, with 13 becoming seizure-free.

  • Four patients experienced persistent complications (hemiparesis, memory difficulties).
  • No permanent hormonal deficiencies were observed postoperatively.

    • Conclusions:

    • Endoscopic removal or disconnection of sessile hypothalamic hamartomas is feasible with acceptable risk in selected patients.
    • A minimum of one year follow-up is necessary to fully assess seizure control and behavioral improvements.
