Novel Suturectomy Using Absorbable Plates in Early Surgery for Craniosynostosis
2020
Background In craniosynostosis patients under 3 months of age, suturectomy is a valuable early treatment improving their outcomes. However, conventional suturectomy might not be in severe patients. The efficacy of our developed suturectomy using absorbable plates was examined. Methods Our method was indicated for craniosynostosis patients under 3 months old who had severe intracranial hypertension, scaphocephaly, plagiocephaly, or trigonocephaly between September 2011 and March 2018. All patients underwent suturectomy, and the bone edges on both sides of the cuts were covered with absorbable plates. Evaluation was conducted with 3-dimensional computed tomography and photographs, and cephalic index, distance from dorsum sellae to forehead on computed tomography were analyzed. Results Twenty-one of the 25 patients were evaluated. The preoperative cranial shapes were 4 brachycephaly, 6 scaphocephaly, 5 oxycephaly, 2 clover-leaf deformity, and 4 plagiocephaly. There were 9 syndromic and 12 nonsyndromic patients. The mean age at the time of surgery was 52.3 days (7-89), and the mean follow-up period was 3.5 years (1-8).The cephalic index and cranial definition improved in 18 patients. The secondary surgery was not required in four syndromic and none of the 12 nonsyndromic patients. There were no major complications. Conclusion Placement of absorbable plates was able to prevent bone formation during the early postoperative period, and yet also promote bone formation after plate absorption. The authors believe syndromic craniosynostosis patients with severe deformities and nonsyndromic ones with scaphocephaly or plagiocephaly, successfully avoided secondary surgeries. This approach is less invasive for craniosynostosis and is expected to be highly effective.
