OBJECT

The authors’ aim was perform a systematic review on the incidence of intracranial hypertension (IH) after surgery for craniosynostosis.

METHODS

A systematic literature review was conducted using PubMed to assess the rate of postoperative IH in studies published between 1985 and 2014. Inclusion criteria were 1) English-language literature; 2) human subjects; 3) pediatric cases; and 4) postoperative IH confirmed with invasive intracranial pressure monitoring.

RESULTS

Seven studies met inclusion criteria. IH was reported to be present in 5% of patients postoperatively with sagittal synostosis and 4% of patients with all forms of nonsyndromic craniosynostosis. Inadequate numbers were available to determine the incidence of postoperative IH for syndromic and individual nonsyndromic sutural synostosis based on the inclusion criteria. Surgical groups were subdivided into cranial remodeling procedures without orbital advancement and craniofacial procedures with orbital advancement. IH was reported to be present in 5% of patients with all forms of nonsyndromic sutural stenosis after cranial remodeling procedures and 1% after craniofacial advancement.

CONCLUSIONS

Postoperative development of elevated intracranial pressure has been described by multiple institutions, but the variation in how IH is determined and the multiple surgical procedures to correct craniosynostosis has limited the number of studies subject to a meta-analysis. Nonetheless, this entity deserves special attention, and further studies are required to determine the true incidence of postoperative IH, including the role of various surgical procedures on its incidence. The long-term consequences of chronic IH in this group of patients also need to be evaluated.

OBJECTIVE

The authors created a collaborative network, the Synostosis Research Group (SynRG), to facilitate multicenter clinical research on craniosynostosis. To identify common and differing practice patterns within the network, they assessed the SynRG surgeons’ management preferences for sagittal synostosis. These results will be incorporated into planning cooperative studies.

METHODS

The SynRG consists of 12 surgeons at 5 clinical sites. An email survey was distributed to SynRG surgeons in late 2016, and responses were collected through early 2017. Responses were collated and analyzed descriptively.

RESULTS

All of the surgeons—7 plastic/craniofacial surgeons and 5 neurosurgeons—completed the survey. They varied in both experience (1–24 years) and sagittal synostosis case volume in the preceding year (5–45 cases). Three sites routinely perform preoperative CT scans. The preferred surgical technique for children younger than 3 months is strip craniectomy (10/12 surgeons), whereas children older than 6 months are all treated with open cranial vault surgery. Pre-incision cefazolin, preoperative complete blood count panels, and an arterial line were used by most surgeons, but tranexamic acid was used routinely at 3 sites and never at the other 2 sites. Among surgeons performing endoscopic strip craniectomy surgery (SCS), most create a 5-cm-wide craniectomy, whereas 2 surgeons create a 2-cm strip. Four surgeons routinely send endoscopic SCS patients to the intensive care unit after surgery. Two of the 5 sites routinely obtain a CT scan within the 1st year after surgery.

CONCLUSIONS

The SynRG surgeons vary substantially in the use of imaging, the choice of surgical procedure and technique, and follow-up. A collaborative network will provide the opportunity to study different practice patterns, reduce variation, and contribute multicenter data on the management of children with craniosynostosis.
