Craniosynostosis Surgery for Increased Intracranial Pressure

Introduction: Craniosynostosis is the premature fusion of 1 or more cranial sutures. The presentation may vary, and there are differing opinions regarding surgical indications and timing. Though increased intracranial pressure (ICP) is a well-established risk of craniosynostosis, its response to treatment is not uniform. This study aims to identify the signs and symptoms indicative of increased ICP that are most likely to improve after craniosynostosis surgery. Methods: Pre- and post-operative data were retrospectively collected from patients at our institution with syndromic and non-syndromic craniosynostosis from January 2009 to June 2020. Demographics, symptoms (headache, nausea, emesis, and lethargy), signs (visual disturbances and papilledema), and imaging characteristics (copper beaten changes), if available, were analyzed. Results: One hundred fifty-three children with craniosynostosis were identified, and 56 with preoperative symptoms met inclusion criteria. Older age was significantly correlated with the number of symptoms improved postoperatively (P = 0.015). Papilledema, headache, nausea, and irritability (if present preoperatively) were the features most likely to improve after craniosynostosis repair. Optic nerve or disc anomalies, feeding difficulties, seizures, and need for glasses were least likely to improve. Conclusions: Older children undergoing craniosynostosis surgery had a greater number of improved symptoms. Classical features of increased ICP were more likely to improve than developmental difficulties and multifactorial causes. These findings may be useful when considering craniosynostosis repair in a symptomatic child.
