Surgical decompression for Chiari malformation type I, relieving cerebellar tonsillar herniation and associated syringomyelia. Chinese neurosurgery departments perform posterior fossa decompression with or without duraplasty, tailored to individual pathology. High surgical volumes at specialized centers contribute to refined techniques and excellent outcomes at a fraction of Western costs.
Pre-operative Assessment
Brain and cervical spine MRI to measure tonsillar descent, assess CSF flow, evaluate syrinx if present, and cine-MRI for CSF flow dynamics at the foramen magnum.
Duration: 1-2 daysPosterior Fossa Decompression
Suboccipital craniectomy to remove bone compressing the cerebellum, often combined with C1 laminectomy to widen the foramen magnum and restore CSF flow.
Duration: 2-3 hoursDuraplasty (if indicated)
Opening of the dura and sewing in a patch graft to expand the posterior fossa space, ensuring adequate CSF flow around the cerebellar tonsils.
Duration: Additional 1-2 hoursPost-operative Recovery
Neurological monitoring, pain management, early mobilization, and follow-up MRI to confirm improved CSF flow and syrinx reduction.
Duration: 4-5 days- Relieves headaches, neck pain, and neurological symptoms
- Halts or reverses syringomyelia progression
- High success rate (80-90%) for symptom improvement
- Significant cost savings compared to Western neurosurgery
- CSF leak requiring additional repair (5-10%)
- Headache and neck stiffness during initial recovery
- Rare risk of cerebellar injury or brainstem compression
- Symptoms may not fully resolve if nerve damage has occurred
