Long-Term Outcomes of Pediatric Cranial Reconstruction Using Resorbable Plating Systems for the Treatment of Craniosynostosis.
BACKGROUND
Resorbable plating in cranial reconstruction for craniosynostosis has fewer reported complications than rigid hardware. Few long-term outcome studies exist for pediatric patients treated with this technology for cranial vault reconstruction.


METHODS
A retrospective review was performed on pediatric patients undergoing cranial vault reconstruction for craniosynostosis by 3 surgeons over a 15-year period. MacroPore (Cytori Therapeutics, San Diego, CA) or Lactosorb (Walter Lorenz Surgical Inc, Jacksonville, FL), composed of polyglycolic and polylactic acids, was used for resorbable plate fixation.


RESULTS
A total of 203 patients underwent resorbable plate fixation with a mean age of 15.8 months at surgery. Mean length of follow-up was 6.4 years. Lactosorb plating system was used in the majority of patients (74%) compared with MacroPore plating system (26%). Overall, unplanned reoperations were required in 5.4% of patients. Palpable hardware was noticed in 10.3% of patients. Only 3 patients (1.5%) developed exposure of the resorbable hardware requiring removal, all MacroPore plates. Four patients (2%) developed surgical site infection and 3 patients (1.5%) developed a seroma. There were 15.8% requiring later surgical revision with cranial vault expansion or cranioplasty with grafts for residual cranial defects. The majority of revisional reoperations (81%) occurred in the first half of the study before the addition of Allogenix.


CONCLUSIONS
Resorbable plating systems, specifically Lactosorb, for cranial reconstruction are a safe, reproducible, inexpensive modality with very low complication rates. They have 3-dimensional stability, rigid fixation without causing growth restriction, and lower likelihood of need for removal.
