Chiari malformation is a structural defect in the skull where the lower part of the brain (cerebellar tonsils) extends into the spinal canal, putting pressure on the brainstem and spinal cord. This can block the flow of cerebrospinal fluid (CSF), leading to symptoms like:
Chiari malformations are often congenital but may remain undiagnosed until adulthood. Chiari decompression surgery is the most common treatment for moderate to severe cases.
The standard surgical procedure is called posterior fossa decompression. It involves removing a small section of bone at the back of the skull to relieve pressure and restore normal CSF flow.
Procedure Overview:
Our partner hospitals utilize advanced neurosurgical tools and imaging systems to improve outcomes and reduce risks:
1. Intraoperative Neuro-Navigation
High-resolution MRI and CT scans guide the surgeon in real-time to target the exact compression area and avoid critical structures.
2. Intraoperative MRI & Ultrasound
Live imaging during surgery allows the surgeon to verify CSF flow restoration and brain tissue decompression before closing.
3. Minimally Invasive Techniques
In select cases, minimally invasive Chiari decompression using smaller incisions and advanced tools leads to faster recovery, less pain, and minimal scarring.
4. Intraoperative Neurophysiological Monitoring (IONM)
Used during surgery to track spinal cord and brainstem function in real time—ensuring patient safety throughout the procedure.
Chiari decompression surgery is considered safe and effective when performed by experienced neurosurgeons in accredited hospitals.
Safety Profile:
Common risks like infection, CSF leaks, or bleeding are rare and manageable with proper post-op care.
