    Abstract:
    OBJECTIVE: To explore the feasibility and therapeutic effect of anterior and posterior vault distraction osteogenesis (A-PVDO) in the treatment of infantile syndromic craniosynostosis. METHODS: Between January 2017 and December 2019, 7 children with syndromic craniosynostosis underwent osteotomy with Piezo-surgery at our hospital. The first step was to harvest the frontal bone flap and the orbitofrontal bone flap. The second step was to separate the scalp and expose the posterior occipital. Osteotomy was performed on the occipital tubercle. Thereafter, 2 distractors were horizontally installed on the upper edge of the anterior cranial orbit, 2 distractors of 3 cm were installed on the posterior cranial bone. Meanwhile, lambdoidal sutures were fixed by titanium plates. Bone distraction was initiated on postoperative day 5 at the rate of 0.4 to 0.6 mm/day, twice per-day, for a total of 10 to 15 days. After 6 months, the distractors and the titanium plates were removed by secondary surgery. RESULTS: The intracranial volume and posterior cranial morphology were recorded during the follow-up of 6 to 14 months (average = 12 months). The posterior craniums of 7 cases with lambdoidal sutures fixation were completely extended. The anterior cranial morphology was normal. All the cranial deformities were significantly improved. There were no severe complications, such as death, cranial necrosis, and intracranial infection. CONCLUSIONS: A-PVDO is an ideal method for the treatment of severe syndromic craniosynostosis, which can achieve more natural appearance than anterior vault distraction osteogenesis or posterior vault distraction osteogenesis. Moreover, A-PVDO causes no severe complications and is suitable for the treatment of severe syndromic craniosynostosis.
