Abstract

Introduction: Craniosynostosis is a group of diseases whose main characteristic is the premature fusion of one or more cranial sutures. They can be subdivided into non-syndromic and syndromic. The posterior vault distraction osteogenesis (PVDO) has become the standard procedure for managing the intracranial hypertension of these patients. The objective of this paper is to report the experience of the Sobrapar Hospital (Campinas, Brazil) in treating and following up on syndromic craniosynostosis patients subjected to PVDO and highlight the lessons learned throughout this process.

Methods: The medical records of the patients treated at the Sobrapar Hospital between 2013 and 2023 were reviewed.

Results: The total of patients initially candidates to PVDO was 79, and 75 of them proceeded to the surgery. The mean age of surgery was 8,16 months old (ranging from 4 months to 12 years old). The length of stay ranged from 2 to 14 days, with a mean of 3,29 days. The distraction achieved ranged from 13 mm to 30 mm, with a mean distance of 23 mm. The postoperative complications were mostly cutaneous. CSF leak occurred in 3 patients.

Conclusion: PVDO provides a progressive formation of a vascularized bone, its intracranial volume expansion is greater than the FOA, increasing the posterior fossa’s size (even when the craniotomy is supratorcular) and it improves Chiari’s symptoms, even when the radiologic abnormalities are not necessarily solved. A specialized and multidisciplinary team is essential to improving the success rates of the surgery.
