OBJECTIVE: Pilot study evaluation of the benefit of piezoosteotomy in cranioplasty of craniosynostoses, based on clinical data.
DESIGN: Retrospective case-control study.
SETTING: Universitarian institution.
PATIENTS: Craniosynostosis patients (n = 19) operated upon conventionally with a craniotome and microsaw versus 19 patients operated upon with a piezoosteotomy and a craniotome.
INTERVENTION: Piezoosteotomy of the supraorbital "bandeau" and osteotomies on part of the parietal and occipital regions versus conventional saw-and-chisel osteotomy.
MAIN OUTCOME MEASURES: Perioperative age, weight, laboratory parameters, transfusion and infusion requirements, operation time, and blood loss.
RESULTS: The intraoperative erythrocyte concentrate transfusion and noncolloidal infusions were comparable (P = .15; P = .56). The fresh frozen plasma transfusion was significantly higher (P = .03); possibly, the anesthesiologist's reaction was secondary to the higher irrigation-fluid accumulation in the aspiration bag during piezoosteotomy. The postoperative erythrocyte concentrate transfusion rate was significantly lower (P = .01) as a result of local hemostasis in piezoosteotomy. The fresh frozen plasma transfusion and noncolloidal infusion volumes were nonsignificantly lower (P = .27; P = .85). Operation time was slightly shorter with a smaller standard deviation (P = .09), due to a lower rate of dural lacerations and consecutive repair; patients in the study group were on the intensive care unit half a day less (P = .73) than those in the control group. C-reactive protein was significantly lower preoperatively (P = .00) and on the operation day (P = .01) and nonsignificant postoperatively (P = .81); hematocrit was postoperatively higher (P = .23). Thrombocytes were preoperatively lower and postoperatively higher, both nonsignificant (P = .29; P = .52).
CONCLUSIONS: Piezoosteotomy appears to be less traumatic than conventional saw-and-chisel osteotomy by the evaluated parameters. The main study limitation is its nonrandomized retrospective design; results should be confirmed by a randomized controlled trial.
