Summary
Endoscopic surgery for hypothalamic hamartomas (HH) in children is safe and effective, with thulium laser disconnection showing promise. This approach offers good seizure control and low complication rates, making it a valuable treatment option.
Area of Science:
- Neurosurgery
- Pediatric Neurology
- Minimally Invasive Surgery
Background:
- Endoscopic intraventricular procedures are a viable treatment for hypothalamic hamartomas (HH).
- Thulium laser disconnection is an emerging alternative to traditional monopolar techniques for HH treatment.
Purpose of the Study:
- To present a consecutive surgical series of pediatric cases with HH treated endoscopically.
- To conduct a meta-analysis of existing literature on endoscopic HH treatment in children.
- To evaluate the efficacy and safety of thulium laser disconnection for HH.
Main Methods:
- Retrospective review of 15 pediatric patients treated between 2016-2023.
- Meta-analysis including 8 studies and the current series (302 patients total).
- Assessment of epilepsy outcomes (Engel class) and postoperative complications.
Main Results:
- 40% of patients were seizure-free, and 60% showed improved seizure control post-surgery.
- Overall complication rate was approximately 5%, with memory deficits and thalamic infarcts being most common.
- The meta-analysis of 302 patients showed 52% achieved Engel class I and 69% Engel class I-II seizure control.
Conclusions:
- Endoscopic procedures for pediatric HH are safe and effective for epilepsy management.
- Thulium laser disconnection is a potentially attractive tool for disconnection procedures in HH.
- Further research with larger studies is needed to validate thulium laser disconnection in pediatric HH.
