Summary
A novel cranial fixation device enabled precise intracranial endoscopy for treating obstructive hydrocephalus in a child. This neuronavigation tool improved outcomes for complex pediatric neurosurgery cases.
Area of Science:
- Neurosurgery
- Medical Device Technology
- Pediatric Neurology
Background:
- Intracranial endoscopy requires precise point-to-point navigation for introducing the endoscope and identifying target structures within cerebrospinal fluid spaces.
- Obstructive hydrocephalus and large cysts present significant challenges in pediatric neurosurgery, particularly in young children or those with small ventricles.
Observation:
- An 18-month-old female child with macrocephaly, developmental delay, and hemiparesis due to a suprasellar cyst and obstructive hydrocephalus was treated.
- A novel ball-stem device adapted for direct cranial fixation and neuronavigation was utilized with a rigid ventricular endoscope.
Findings:
- The device facilitated successful MR-based neuronavigation and cyst fenestration.
- Post-operatively, the child experienced resolution of macrocephaly, developmental delay, and hemiparesis within seven months.
Implications:
- This cranial fixation and neuronavigation system offers a potential solution for challenging pediatric neurosurgical cases, including those with small ventricles or ambiguous landmarks.
- The device's direct cranial fixation may be advantageous for infants and young children unable to tolerate traditional head-holder immobilization.
- This approach enhances the safety and efficacy of intracranial endoscopy in pediatric neurosurgery.
