Posterior Cranial Retraction Combined With Bilateral Parietal Distraction for Children With Nonsyndromic Craniosynostosis

Background The nonsyndromic craniosynostosis is the most common of craniosynostoses in childhood. There are many treatments. We aim to treat 12 cases of nonsyndromic craniosynostosis via posterior cranial vault distraction osteogenesis combined with bilateral parietal distraction. Methods Data of a total of 12 patients (7 boys and 5 girls) with nonsyndromic sagittal synostosis who underwent distraction osteogenesis between January 2015 and August 2020 were retrospectively analyzed. Bilateral parietal bone flaps and posterior occipital flaps were designed and cut. Then, distraction device was placed, which was distracted at 5 days after surgery (twice per day, 0.4–0.6 mm/d, and lasting for 10–15 days). After 6 months of fixation, the secondary surgery was performed to remove the device. Results The scaphocephaly was corrected, and the appearance was satisfactory. Postoperative follow-up time was 6 to 14 months, with an average of 10 months, and the mean CI was 63.2 and 78.25 before and after surgery, respectively; the mean anterior-posterior skull diameter was shortened (12.63 ± 3.47) mm, the transverse diameter of both temporal regions was lengthened (15.4 ± 4.18) mm, and the scaphocephalic deformity was significantly improved. There was no detachment or rupture of the extender postoperatively. No severe complications, such as radiation necrosis or intracranial infection, were observed. Conclusion Posterior cranial retraction combined with bilateral parietal distraction in children with nonsyndromic craniosynostosis, in which the proposed technique did not exhibit severe complications, and it is worthy of further promotion and application in clinical practice.
