Pediatric Chiari Malformation Management: WFNS Spine Committee Recommendations

Area of Science:

• Pediatric Neurosurgery
• Neurology
• Spine Surgery

Background:

• Chiari malformation (CM) in children poses unique management challenges distinct from adult cases.
• A global need exists for educating general neurosurgeons on pediatric CM due to a scarcity of pediatric specialists.

Purpose of the Study:

• To provide an overview of Chiari malformation in pediatric patients.
• To highlight specific clinical manifestations and surgical treatment options for pediatric CM.

Main Methods:

• A systematic literature review of PubMed articles from the last 10 years.
• Consensus reached via the Delphi method among expert spine surgeons from the World Federation of Neurosurgical Societies (WFNS) Spine Committee.

Main Results:

• Decompressive surgery with duraplasty before puberty may prevent scoliosis progression in CM1.
• Urgent craniovertebral junction decompression is recommended for Chiari type 2 without hydrocephalus decompensation.
• Cranial vault expansion may be considered for pediatric CM associated with craniosynostosis.

Conclusions:

• Pediatric age significantly influences Chiari malformation management strategies.
• Timely diagnosis and surgical intervention, particularly before puberty, are vital for optimal pediatric outcomes.
• Enhanced awareness and access to specialized neurosurgical care are critical, especially for Type 2 CM.
