Chiari malformation is a condition where brain tissue extends into the spinal canal due to a structural defect in the skull. Dr. Salim performs advanced decompression surgeries to relieve pressure on the brain and spinal cord, restoring normal cerebrospinal fluid flow and improving neurological function.
What Is Chiari Malformation?
Chiari malformation occurs when part of the cerebellum (the lower back of the brain) descends below the skull into the upper spinal canal. This can block the normal flow of cerebrospinal fluid (CSF) and compress neural tissues, leading to a wide range of symptoms.
It is often congenital (present at birth) but can also develop later in life.
Types of Chiari Malformation
- Type I – Most common; cerebellar tonsils extend into the spinal canal
- Type II – Associated with spina bifida and more severe brainstem displacement
- Type III and IV – Rare and usually diagnosed in infancy with more serious complications
Dr. Salim primarily treats Type I, which is often diagnosed in adolescence or adulthood.
Symptoms
Not everyone with Chiari malformation experiences symptoms, but common complaints include:
- Headaches (especially at the back of the head)
- Neck pain
- Balance and coordination problems
- Muscle weakness or numbness
- Difficulty swallowing or speaking
- Dizziness or vision problems
- Tinnitus or hearing issues
- Sleep apnea
Diagnosis and Evaluation
Diagnosis involves a detailed neurological assessment and imaging, including:
- MRI – The most accurate tool for visualizing cerebellar descent
- Cine MRI – To assess CSF flow blockage
- CT scans – If bone structure assessment is needed
- Neurological and physical evaluations – To gauge the severity of symptoms
Surgical Treatment: Posterior Fossa Decompression
Surgery is considered when symptoms affect daily life or if CSF flow is impaired.
Posterior Fossa Decompression is the most common surgery and involves:
- Removing a small portion of the skull at the back (suboccipital craniectomy)
- Possibly removing part of the top vertebra (C1 laminectomy)
- Opening and repairing the dura (protective brain covering) if needed
Goal: create more space for the cerebellum and restore CSF flow.
Recovery and Results
- Hospital stay: 3–5 days
- Most patients experience relief from headaches and balance issues within weeks
- Full recovery can take 1–3 months
- Follow-up MRIs are performed to ensure proper healing and CSF circulation
Risks and Considerations
While generally safe, Chiari decompression surgery may involve:
- CSF leakage
- Infection
- Blood clots
- Persistent symptoms (rare)
- Need for reoperation in a small number of cases
Dr. Salim uses intraoperative monitoring and meticulous technique to reduce these risks.
