Pediatric Neurosurgery
Pediatric Neurosurgery is a specialized branch of neurosurgery that focuses on diagnosing, treating, and managing neurological conditions in infants, children, and adolescents. It deals with the surgical intervention of disorders affecting the brain, spinal cord, and peripheral nervous system in young patients. Due to the unique developmental and physiological differences in children compared to adults, pediatric neurosurgery requires specialized knowledge and techniques to address these conditions safely and effectively.
1. Congenital Disorders
Congenital neurological conditions are present at birth and require early diagnosis and intervention.
- Spina Bifida: A birth defect where the spinal cord fails to develop properly. Surgery may be required shortly after birth to repair the defect and prevent damage to the spinal cord.
- Hydrocephalus: A condition characterized by an accumulation of cerebrospinal fluid (CSF) in the brain, leading to increased intracranial pressure. This is often managed with a shunt to divert the fluid to another part of the body.
- Chiari Malformation: A condition in which brain tissue extends into the spinal canal, often leading to headaches, neck pain, and neurological symptoms.
- Agenesis of the Corpus Callosum: A condition where the corpus callosum (a bundle of nerve fibers connecting the brain's two hemispheres) does not fully develop, leading to developmental delays and seizures.
2. Brain Tumors
Brain tumors in children, though less common than in adults, can be life-threatening and require surgical intervention.
- Astrocytomas: Tumors arising from glial cells in the brain, often treated with surgery, radiation, or chemotherapy.
- Medulloblastomas: A malignant tumor in the cerebellum that is often treated with surgical removal, followed by radiation or chemotherapy.
- Ependymomas: Tumors that arise from the cells lining the ventricles of the brain or the spinal cord.
- Craniopharyngiomas: Benign tumors near the pituitary gland that can affect vision, hormone regulation, and growth.
3. Epilepsy and Seizure Disorders
Pediatric neurosurgeons may treat children with severe epilepsy or refractory seizures that do not respond to medication.
- Focal Cortical Dysplasia: A brain malformation that may lead to intractable seizures, often requiring resection of the affected brain tissue.
- Hemimegalencephaly: A condition where one side of the brain is abnormally large, leading to seizures and developmental delays.
- Vagus Nerve Stimulation (VNS): This is sometimes used to treat seizure disorders when medications are ineffective, particularly when surgical resection is not possible.
4. Craniosynostosis
Craniosynostosis is a birth defect where the bones in a baby’s skull join together too early, restricting skull and brain growth. Surgical intervention is often required to correct the shape of the skull and allow for normal brain development.
- Types: The most common types include scaphocephaly, brachycephaly, and plagiocephaly.
- Procedure: The surgeon may perform a procedure to remove the fused suture and reshape the skull, allowing the brain to grow properly.
