Abstract：
OBJECTIVE: The purpose of this study is to analyze cranial width and length growth curves in the early postoperative period of patients by undergoing endoscopic sagittal strip craniectomy (ESC) to determine the timing of the maximal growth curve change. By analyzing the complex interplay of cephalic length and width measurements, we hope to better understand the cephalic index (CI) growth curve during this early period. This is the first of a multistep process to elucidate the ideal cranial remolding orthosis (CRO) treatment duration.
METHODS: Retrospective review.
METHODS: Tertiary academic institution.
METHODS: Children with isolated sagittal craniosynostosis.
METHODS: ESC and postoperative CRO treatment (2015-2019).
METHODS: One cranial orthotist obtained preoperative and postoperative measurements. The maximal rate of change of width, length, and CI were compared against the postoperative week these occurred.
RESULTS: Thirteen children (mean age: 3.3 months, average preoperative CI: 73.4) underwent this intervention. CI reached its highest growth rate by 4.9 average weeks postoperatively, which correlated with the maximal width growth rate (5.2 weeks). Length curves reached their maximal growth rate by 15.5 weeks. CI peaked (81.3) by 22.7 weeks postoperatively, a significant increase from baseline.
CONCLUSIONS: Following ESC, in the early postoperative period, the CI growth curve has 4 phases: initial rapid expansion, early and late slowed expansion, and plateau, followed by possible regression phases. This highlights the importance of early postoperative CRO initiation, CRO compliance, and properly fitting CROs, especially in the first 2 phases. This data sets the stage for investigating the ideal treatment length.

摘要：
目的：本研究的目的是通过内窥镜矢状面骨瓣开颅术（ESC）分析患者术后早期的颅骨宽度和长度生长曲线，以确定最大生长曲线变化的时机。通过分析头长和宽度测量的复杂相互作用，我们希望在这个早期更好地了解头部指数（CI）增长曲线。这是阐明理想的颅骨重塑矫形器（CRO）治疗持续时间的多步骤过程中的第一个。
方法：回顾性回顾。
方法：高等教育机构。
方法：孤立性矢状颅骨融合症患儿。
方法：ESC和术后CRO治疗（2015-2019）。
方法：一名头颅矫形师获得了术前和术后测量结果。宽度的最大变化率，长度,将和CI与这些发生的术后一周进行比较。
结果：13名儿童（平均年龄：3.3个月，平均术前CI：73.4）接受了这项干预。CI在术后平均4.9周达到最高增长率，与最大宽度增长率（5.2周）相关。长度曲线在15.5周时达到其最大生长速率。CI在术后22.7周达到峰值（81.3），从基线显著增加。
结论：在ESC之后，在术后早期，CI增长曲线有4个阶段：初始快速扩张，早期和晚期减缓扩张，高原,其次是可能的回归阶段。这突出了术后早期开始CRO的重要性，CRO合规性,并正确安装CRO，特别是在前两个阶段。该数据为研究理想的治疗长度奠定了基础。
