Paediatric neurosurgery is indicated when structural, congenital, traumatic, or progressive neurological disorders threaten normal development, cognitive function, or survival. The causes of conditions requiring surgery are broad:

1. Congenital Disorders: Neural tube defects such as spina bifida, encephalocele, and anencephaly; craniosynostosis, which results in premature fusion of cranial sutures; Chiari malformations, in which cerebellar tonsils herniate into the spinal canal; Dandy-Walker malformations; and other structural anomalies that may cause hydrocephalus or cranial deformities.

2. Brain and Spinal Tumors: Benign or malignant neoplasms arising from glial cells, neurons, meningeal tissue, or the ventricular system. Common pediatric tumors include medulloblastomas, astrocytomas, ependymomas, and craniopharyngiomas. Tumors may present with headaches, vomiting, neurological deficits, or seizures.

3. Hydrocephalus: Excess cerebrospinal fluid accumulation due to congenital aqueductal stenosis, intraventricular hemorrhage, post-infectious causes, or obstructive lesions, leading to raised intracranial pressure, cranial enlargement, visual impairment, or developmental delays.

4. Vascular Malformations: Arteriovenous malformations, cavernomas, aneurysms, and dural arteriovenous fistulas, which may cause hemorrhage, seizures, or progressive neurological deficits.

5. Epilepsy: Drug-resistant epilepsy in children may require surgical interventions such as cortical resections, hemispherectomy, or laser interstitial thermal therapy to remove or isolate seizure foci.

6. Trauma: Birth-related injuries, falls, motor vehicle accidents, sports injuries, or abusive head trauma necessitating emergency neurosurgical intervention to prevent secondary brain injury and optimize neurological outcomes.

Risk Factors

Several factors increase both the likelihood of requiring surgery and the complexity of management. These include neonatal or premature birth, low birth weight, underlying genetic syndromes, prior surgeries, abnormal anatomical variations, systemic comorbidities (cardiac, pulmonary, or metabolic disorders), and delayed diagnosis. Young age poses additional challenges due to small anatomical structures, limited blood volume, and higher anesthetic sensitivity. The risks of perioperative complications, including hemorrhage, infection, neurological deterioration, and long-term neurodevelopmental impairment, are elevated compared to adults. Family support, early intervention, and careful planning are essential to mitigate these risks.

The presentation of neurosurgical disorders in children is highly variable due to the wide range of functions controlled by the nervous system and the differences in developmental stages. Symptoms can be subtle, especially in infants, or more pronounced in older children. Common presentations include:

1. Developmental Delays: Delayed milestones such as sitting, walking, or speech may indicate underlying CNS abnormalities.

2. Seizures: Focal or generalized seizures, clusters, or drug-resistant epilepsy.

3. Headaches and Vomiting: Often associated with hydrocephalus or intracranial mass lesions; morning headaches may indicate increased intracranial pressure.

4. Cranial Abnormalities: Bulging fontanelles, abnormal head shape, cranial asymmetry, or craniosynostosis.

5. Motor Deficits: Weakness, spasticity, abnormal gait, or hemiparesis.

6. Sensory Deficits: Visual changes, hearing loss, or tactile impairment.

7. Behavioral and Cognitive Changes: Regression in previously acquired skills, irritability, attention deficits, or learning difficulties.

8. Signs of Raised Intracranial Pressure: Papilledema, bradycardia, hypertension, and altered consciousness.

9. Spinal Cord Symptoms: Limb weakness, scoliosis, incontinence, or abnormal reflexes.

In infants, nonspecific symptoms such as poor feeding, irritability, lethargy, or failure to thrive may indicate serious neurological conditions. Early recognition and referral to paediatric neurosurgery are critical to prevent irreversible neurological damage and optimize outcomes.

Diagnosis is a multifaceted process combining history-taking, physical and neurological examination, imaging, neurophysiological studies, and laboratory or genetic assessments.

1. History and Examination: Comprehensive evaluation includes prenatal, perinatal, and postnatal factors, trauma, developmental history, prior infections, and existing neurological or systemic conditions. Physical assessment evaluates cranial size and shape, head circumference, spinal alignment, motor and sensory function, cranial nerve integrity, and reflexes.

2. Imaging: MRI is the gold standard for evaluating soft tissue, brain parenchyma, spinal cord, and complex anatomical relationships. CT scans are used for bone assessment and acute trauma. Advanced modalities, including MR angiography, diffusion tensor imaging, and intraoperative MRI, assist in surgical planning.

3. Neurophysiological Testing: EEG is crucial for seizure localization, nerve conduction studies assess peripheral nerve involvement, and intraoperative neuro-monitoring ensures functional preservation during surgery.

4. Laboratory and Genetic Testing: Metabolic disorders, congenital syndromes, tumor markers, or infectious etiologies may be identified through these tests.

5. Multidisciplinary Assessment: Collaboration with pediatric neurology, oncology, rehabilitation, and genetics ensures comprehensive care and individualized treatment planning.

Preoperative assessment also evaluates anesthesia risk, surgical timing, potential need for staged procedures, and long-term developmental impact.

Paediatric neurosurgical interventions are highly individualized and include both surgical and adjunctive approaches:

Surgical Treatments

1. Hydrocephalus Management: Ventriculoperitoneal or ventriculoatrial shunts, and endoscopic third ventriculostomy.

2. Tumor Resection: Microsurgical, endoscopic, or minimally invasive approaches, often with adjunct chemotherapy or radiation.

3. Cranial Reconstruction: Craniosynostosis repair, craniofacial reconstruction, and skull reshaping to prevent intracranial hypertension and allow normal brain growth.

4. Spinal Surgery: Correction of tethered cords, syringomyelia drainage, spinal tumor removal, and deformity correction.

5. Vascular Surgery: Resection, embolization, or radiosurgery for AVMs, aneurysms, or cavernomas.

6. Epilepsy Surgery: Resection of seizure foci, hemispherectomy, or laser ablation for refractory epilepsy.

7. Trauma Surgery: Craniectomy, hematoma evacuation, skull fracture repair, or spinal stabilization.

8. Minimally Invasive and Endoscopic Procedures: For intraventricular lesions, cyst fenestration, or hydrocephalus management.

Non-Surgical and Adjunctive Treatments

1. Medications: Anti-seizure drugs, anti-inflammatory agents, and intracranial pressure control.

2. Radiation Therapy: Stereotactic or proton beam therapy for neuro-oncologic indications.

3. Rehabilitation Services: Physical therapy, occupational therapy, speech therapy, and cognitive rehabilitation.

4. Developmental and Educational Support: Addressing cognitive, motor, and social challenges to ensure holistic recovery.

Integration of minimally invasive techniques and intraoperative neuro-monitoring has enhanced safety, functional outcomes, and recovery speed.

Prevention:

1. Prenatal care, maternal folate supplementation, and avoidance of teratogens reduce neural tube defects.

2. Safe infant care, injury prevention, and vaccination protect against trauma or CNS infections.

3. Early screening and developmental surveillance allow timely interventions for congenital or acquired neurological conditions.

Long-Term Management:

1. Multidisciplinary care focuses on neurodevelopment, cognitive growth, rehabilitation, and psychosocial support.

2. Regular imaging and neurological follow-up detect recurrence or complications.

3. Transition planning ensures continuity of care into adolescence and adulthood.

4. Families receive education on long-term needs, therapy compliance, and psychosocial support, optimizing functional outcomes and life quality.

Short-Term Complications:

1. Hemorrhage, hematoma, infection, CSF leaks, neurological deterioration, and anesthesia-related issues.

Long-Term Complications:

1. Shunt malfunction, cranial growth disturbances, residual or recurrent neurological deficits, seizure recurrence, spinal deformities, cognitive impairments, and psychological challenges.

Minimizing risks requires meticulous surgical technique, postoperative monitoring, rehabilitation, and active family involvement.

Short-Term Recovery:

1. ICU monitoring, wound care, pain management, early mobilization, and therapy initiation.

2. Caregivers must recognize warning signs and adhere to strict post-operative care instructions.

Long-Term Adaptation:

1. Continued therapy, educational support, periodic imaging, and neurological follow-up.

2. Psychosocial support, school accommodations, and adaptive devices ensure maximal independence.

3. Transition to adult care provides ongoing neurological and developmental monitoring.

Paediatric neurosurgery aims to give children the opportunity for optimal functional, cognitive, and social outcomes despite complex neurological conditions.
