Insights
Early posterior vault distraction osteogenesis in children with syndromic craniosynostosis safely remodels the skull. This reduces the need for and delays initial fronto-orbital advancement procedures, improving outcomes.
Area of Science:
- Craniofacial Surgery
- Pediatric Neurosurgery
- Plastic Surgery
Background:
- Syndromic craniosynostosis presents complex challenges in cranial vault remodeling.
- Current treatment paradigms often involve multiple surgical interventions.
- The timing and necessity of fronto-orbital advancement are critical considerations.
Purpose of the Study:
- To evaluate the efficacy of early posterior vault distraction osteogenesis (PVD) in managing syndromic craniosynostosis.
- To determine if PVD can delay or obviate the need for fronto-orbital advancement (FOA).
- To assess the impact of PVD on the total number of major craniofacial procedures.
Main Methods:
- Retrospective cohort study comparing patients treated before and after PVD implementation.
- Inclusion criteria focused on care continuity and complete medical records.
- Kaplan-Meier survival analysis was used to compare the timing of FOA.
Main Results:
- Fewer patients undergoing PVD required subsequent FOA (11/18) compared to the pre-PVD group (22/22).
- Significant delay in the first FOA was observed in the PVD cohort (p = 0.011).
- Patients receiving PVD had fewer FOA procedures in the first five years of life (0.6 vs 1.5 per patient, p = 0.023).
Conclusions:
- Early PVD is a safe and effective method for cranial vault remodeling in syndromic craniosynostosis.
- PVD significantly reduces the number and delays the timing of FOA procedures.
- This approach is likely to decrease the overall number of major craniofacial surgeries required.
Background:
The authors hypothesize that early posterior vault distraction osteogenesis safely confers considerable cranial vault remodeling, sufficient to enable fronto-orbital advancement to be delayed to a later age, with improved outcomes.
Methods:
The authors conducted a retrospective cohort study of children with syndromic craniosynostosis treated before (2003 to 2008) or after (2009 to 2014) implementation of posterior vault distraction osteogenesis.
Results:
Sixty children with syndromic craniosynostosis presented during the study period. Forty met inclusion criteria with care continuity and complete records: 22 before and 18 after implementation of posterior vault distraction osteogenesis. Only 11 patients (61 percent) who underwent initial posterior vault distraction osteogenesis required frontal advancement, at a mean follow-up of 4.0 years of age, compared with 22 patients (100 percent) before implementation of posterior vault distraction osteogenesis. Kaplan-Meier survival analysis indicated significant delay of first fronto-orbital advancement in the posterior vault distraction osteogenesis cohort compared with the pre-posterior vault distraction osteogenesis cohort (p = 0.011). Comparing treatment in the first 5 years of life among posterior vault distraction osteogenesis versus non-posterior vault distraction osteogenesis subcohorts of patients older than 5 years, there were significantly fewer fronto-orbital advancements performed (0.6 versus 1.5 per patient; p = 0.023).
Conclusion:
Using early posterior vault distraction osteogenesis for patients with syndromic craniosynostosis significantly reduces the average number of fronto-orbital advancement procedures in the first 5 years of life, delays initial fronto-orbital advancement, and is likely to reduce the total number of major craniofacial procedures.
