Intracranial pressure changes in craniostenosis.

Area of Science:

• Pediatric Neurosurgery
• Craniofacial Surgery

Background:

• Craniostenosis, a premature fusion of cranial sutures, can lead to abnormal head shape and potentially affect brain development.
• Elevated intracranial pressure (ICP) is a significant concern in craniostenosis, but its prevalence and detection can be challenging with standard clinical assessments.

Purpose of the Study:

• To investigate intracranial pressure (ICP) dynamics in children diagnosed with craniostenosis.
• To evaluate the utility of continuous ICP monitoring in identifying intracranial hypertension and assessing surgical outcomes.

Main Methods:

• Continuous intracranial pressure monitoring was performed in 20 pediatric patients with craniostenosis.
• ICP data were analyzed in relation to clinical presentation, suture involvement, presence of hydrocephalus, and post-surgical recovery.

Main Results:

• 13 out of 20 children (65%) exhibited persistent or episodic raised intracranial pressure, despite only one showing overt clinical or radiological signs of intracranial hypertension.
• Raised ICP was observed in cases with single and multiple suture involvement, and in 4 of 6 patients with co-existing hydrocephalus.
• Post-surgical ICP monitoring in nine patients showed a significant delay (several months) in normalization, even after adequate bony decompression.

Conclusions:

• Continuous ICP monitoring provides crucial insights beyond clinical evaluation in craniostenosis management.
• This method is valuable for accurately diagnosing intracranial hypertension and determining the necessity and effectiveness of surgical interventions.
• Delayed ICP normalization post-surgery suggests the need for extended monitoring and potentially revised treatment strategies.
