Surgical Correction of Unicoronal Craniosynostosis with Frontal Bone Symmetrization and Staggered Osteotomies.

Abstract

Background: Craniosynostosis is the premature fusion of one or more cranial sutures that produce abnormal head shape. Plagiocephaly is a general term that describes unilateral flattening of the anterior or posterior quarter of the cranium. Anterior plagiocephaly is almost always due to unilateral coronal synostosis. Early surgical treatment is the best option for these patients. The aim of this study was to investigate the surgical correction results of unicoronal craniosynostosis with frontal bone symmetrization and staggered osteotomies.

Methods: All unicoronal craniosynostosis cases treated surgically from 2013 to 2016 at our hospital, with frontal bone symmetrization and staggered osteotomies and fronto-orbital advancement, were reviewed. The following variables were analyzed: sex, age, weight, hospital stay time, ICU stay time, per os (PO) starting time, anesthetic time, estimated blood loss volume (ml), estimated blood loss as percentage of total volume, surgical complication, follow-up time, and Whitaker grade. All data were analyzed with SPSS.

Results: The study consisted of 33 patients (19 females, 14 males). Average age was 10.24 months, average weight was 8.97 Kg, average hospital stay time was 7.84 days, average ICU stay time was 1.69 days, average PO starting time was 1.24 days after surgery, average anesthetic time was 397.72 minutes, average estimated blood loss was 213.78 ml, and estimated blood loss as percentage of total volume was 31.69%. One case (3.03%) needed reoperation and two cases had postoperative seizure. No mortality was seen.

Conclusion: It is supposed that surgical correction of unicoronal craniosynostosis with frontal bone symmetrization and staggered osteotomies results in lower blood loss, lower complication rate and reoperation, and more durable results.
