Area of Science:

  • Neurology
  • Neurosurgery
  • Medical Genetics

Background:

  • Chiari malformations (CM) are characterized by cerebellar tonsil or vermis descent into the cervical spinal canal.
  • Associated conditions include hydrocephalus, spina bifida, syringomyelia, spinal curvature, and tethered cord syndrome.
  • CM can be linked to hereditary syndromes affecting bone formation, such as craniosynostosis and Ehlers-Danlos syndromes.

Purpose of the Study:

  • To review the existing literature on Chiari malformations.
  • To discuss historical background, anatomical forms, pathophysiology, and clinical presentation.
  • To explore diagnostic procedures and relationships with other diseases.

Main Methods:

  • Comprehensive literature review.
  • Analysis of therapeutic protocols and surgical indications.
  • Discussion of controversies in surgical timing and technique.

Main Results:

  • The literature predominantly favors surgical intervention for Chiari malformations.
  • There is ongoing debate regarding optimal surgical timing and the most effective procedures.
  • Recent discussions focus on the indications for stabilization procedures.

Conclusions:

  • This review synthesizes current knowledge on Chiari malformations.
  • It highlights the complexities in diagnosis and management.
  • It underscores the need for continued research into optimal treatment strategies.
