Comparison of Distraction Osteogenesis and Single-Stage Remodeling for Correction of Unilateral Coronal Craniosynostosis

Background: Unilateral coronal craniosynostosis is a challenging condition in craniofacial surgery. Frontoorbital advancement by single-stage resorbable remodeling and distraction osteogenesis (DO) techniques have known intraoperative differences, but their comparative outcomes are less well characterized. Methods: A systematic literature search of the MEDLINE, EMBASE, LILACS, and Web of Science databases was conducted. The search was performed using terms related to craniosynostosis and its operative management. The primary outcome of interest was the Whitaker classification. Secondary outcomes included cranial volume or cranial index change, and infection and reoperation rates. Results: A total of 6978 eligible articles were identified of which 26 met inclusion criteria. A total of 292 patients were included in the studies, with 223 undergoing a single-stage remodeling procedure (76.4%) and 69 DO procedures (23.6%). There was a trend toward patients with DO having better Whitaker aesthetic outcomes. Only 2 studies reported volumetric changes. There was a substantial difference in planned and unplanned reoperation rates but not in infection rates. Conclusion: The results of this systematic review suggest that the techniques have similar outcomes and complications, although there was a trend toward better Whitaker outcomes with DO procedures. Inherent to the DO technique is the need for multiple operations to both insert and remove internal hardware which may affect the overall cost effectiveness.
