Incidence of delayed intracranial hypertension in children with isolated sagittal synostosis following open calvarial vault reconstruction

Academic Article


  • Purpose: Delayed intracranial hypertension (DIH) occurs most frequently in children with syndromic or multi-suture synostosis after surgical correction. The rarity of DIH in children with isolated non-syndromic sagittal synostosis (ISS) warrants follow-up evaluation by large craniofacial centers until skeletal maturity. This study reports the incidence of DIH in children following open repair for ISS by our center’s craniofacial team. Methods: A single-center retrospective study of patients who underwent open calvarial vault remodeling (CVR) for ISS at our institution between November 2000 and November 2012 was performed. Syndromic and multi-suture synostosis patients were excluded. Demographic and follow-up data were extracted from the medical record for analysis until July 2017. Results: One hundred five patients with ISS were identified who had undergone CVR in the aforementioned timeframe. Average age at initial surgery was 11.7 ± 15.32 months. Mean follow-up in our craniofacial clinic was 4.94 ± 3.53 years, with 69 patients (65.7%) having follow-up in craniofacial clinic ≥ 3 years and 74 (70.5%) having follow-up ≥ 3 years in any clinic at our institution. Four patients (3.8%) had intracranial pressure (ICP) monitors placed for symptoms concerning for DIH, one of which (0.95%) had confirmed DIH and underwent a second surgical procedure at 7.4 years of age. The patient presented late initially, having his first operation at 1.56 years of age. Conclusion: One patient out of 105 (0.95%) developed DIH, confirmed by ICP monitoring, and required reoperation. The occurrence of DIH, albeit rare, remains an important topic to include in parental discussions and mandates long-term follow-up in this population.
