Purpose: Posterior vault distraction (PVD) has become increasingly accepted as the gold-standard treatment for multisutural and bicoronal craniosynostosis. It provides a significant increase in intracranial volume and improves morphology of the craniosynostosis. We conducted an analysis of the outcomes of PVD at our centre. Method: Patients at Starship Children’s Hospital who underwent PVD from January 2014 to June 2023 had their clinical notes and photography reviewed retrospectively. Data was gathered regarding the indication for the procedure, success in addressing this indication, improvement in appearance and associated complications. Results: During this review period, we performed 25 PVDs in 24 patients. In 23 patients, there was bicoronal or multisutural craniosynostosis and five patients had raised intracranial pressure (ICP) at the time of surgery. Of the patients with raised ICP, one required a second PVD but no others have required further procedures related to ICP. Of the patients with an initially normal ICP, three required further surgery for concerns of raised ICP. Complications included pin site infections that were managed with antibiotics, four episodes of metalware complications in three patients requiring return to theatre, soft spots that did not require treatment in three patients, dural tears and a small extradural haematoma. Conclusion: Our outcomes with PVD show it is a successful and safe procedure for addressing craniosynostosis.
