AbstractPurposeMethodsResultsConclusionsNational Institute of Clinical Excellence (NICE) guidelines advise that paediatric patients with linear skull fractures do not require admission in the absence of intracranial injury. Despite this, a period of inpatient neuro-observation has become the standard advice and practice in the UK for fear of deterioration. Our experience is that these children rarely deteriorate or require neurosurgical intervention. The primary aim of this study was to describe the incidence of neurological deterioration in patients referred to our paediatric neurosurgery unit with linear skull fractures.We identified all patients with a linear skull fracture referred to neurosurgery at a paediatric major trauma centre between 2018 and 2023. Patients with intracranial injury, skull base fracture or major trauma were excluded. Demographic and clinical data were collected. The primary outcome was deterioration which was defined as drop in Glasgow Coma Scale (GCS) score, unplanned repeat cranial imaging, neurosurgical intervention performed, or the patient died.Two hundred and ninety-four patients were identified in our referral database. Infants were the age group most commonly referred (44.2%) and falls from under 2 m in height the most common mechanism of injury (71.4%). Ninety-seven children had specific advice documented regarding neuro-observation; of these, the majority (n = 53) were advised 24 hours of inpatient observation. No patients experienced deterioration.This is the largest cohort of linear skull fractures in children described in the UK. None of our patients experienced neurological deterioration, mirroring findings from international studies and supporting current NICE guidance. In addition, at a cost of £360 per 24-hour admission, this has a cost implication for a resource-scarce NHS. We propose that UK trauma networks should devise protocols to support the safe discharge from ED of such patients without the need for discussion with a neurosurgical department.

AbstractBackgroundMethodsResultsConclusionChiari malformation type 1 (CM1) pathophysiology remains uncertain. One theory involves small posterior fossa volumes leading to tonsillar herniation. Craniosynostosis causes suture fusion, which can limit skull growth, and has been investigated in paediatric CM1 cohorts. We aimed to identify the prevalence of concurrent craniosynostosis in adult CM1 patients.Surgically managed CM1 patients were identified from a pre-existing Edinburgh neurosurgical centres database spanning 10 years. Patients aged 16 years of age or older had their case notes reviewed retrospectively. Cross sectional imaging identified and classified craniosynostosis, tonsillar herniation and the presence of hydrocephalus or syrinxes.35 cases met inclusion criteria. Seven cases (20%) had craniosynostosis, all of which were sagittal synostosis. There was no significant association between the presence of craniosynostosis and the degree of tonsillar herniation, presence of hydrocephalus or syrinx formation.This is the first study to evaluate the prevalence of craniosynostosis in a cohort of surgically managed adult CM1 patients. Future studies should potentially investigate whether conservatively managed adult CM1 patients have similar rates of craniosynostosis and also lack significant associations to known CM1-related complications.
