Wound Healing Complications After Cranial Vault Reconstruction for Craniosynostosis.

Abstract

Craniosynostosis is a congenital cranial malformation involving premature fusion of cranial sutures. Indications for surgical repair of craniosynostosis include elevation of intracranial pressure, which can result in impaired vision and mental disability, as well as correction of abnormal skull shape. Resorbable plating systems have become the preferred technique for bony fixation in the repair of craniosynostosis. Multiple studies demonstrate the safety and low complication rate of resorbable plating systems.However, there is no consensus on which plating system is superior for patient outcomes. This study aims to investigate how the polymer composition of resorbable plating systems utilized in cranial vault reconstruction contributes to wound healing complications. A retrospective chart review was performed at the institution between January 1, 2005 and December 31, 2015. About 202 patients who underwent surgical repair of craniosynostosis were identified. The results showed that patients receiving the Biomet Lactosorb plating system were over twice as likely to have a wound complication within a year of surgery compared to other plating systems used at the institution. Wound complications continued to occur in the Biomet Lactosorb group at ≥180 days after surgery, whereas complications among the other plating systems occurred ≤80 days postoperatively. Half of all patients with wound complications had to undergo reoperation. These data demonstrate the effect of unique polymer compositions on wound healing, and will help to guide future clinical practice and industry development of resorbable plating systems.
