Abstract：
This study describes a modified technique addressing bony defects and incomplete ossification after endoscopic strip craniectomy (ESC) for SC followed by postoperative helmet therapy (PHT). The study aims to delineate quantitative and qualitative outcomes of this modified ESC technique followed by PHT and discern the optimal duration of PHT following ESC. A secondary aim is to address the effects of the technique on bony defects.
Patients undergoing ESC followed by PHT between 2017 and 2021 were included. Patient sex, age at surgery, duration of surgery, red blood cell transfusion, length of hospital stay, PHT duration, cephalic index (CI) at multiple time points, and bony defect information were collected. Descriptive and correlative analysis was done.
Thirty-one patients (25 male, 6 female) were operated in study period. Mean age at surgery was 12.81 weeks, mean duration of surgery was 57.50 min, average transfused RBC volume was 32 cc, mean length of hospital stay was 1.84 days, mean PHT duration was 33.16 weeks, and mean follow-up time was 63.42 weeks. Mean preoperative CI was 70.6, and mean CI at the end of PHT was significantly higher, being 77.1. Maximum improvement in CI (CImax) took place at week 22.97. PHT duration did not have a correlation with CI at last follow up. There were no bony defects.
Modified ESC technique is effective in successful correction of sagittal craniosynostosis. CImax already takes place, while PHT is continuing, but there is no certain time point for dishelmeting. The technique avoided bony defects and incomplete ossification.

摘要：
这项研究描述了一种改进的技术，该技术可解决SC的内窥镜带状颅骨切除术（ESC），然后进行术后头盔治疗（PHT）后的骨缺损和不完全骨化。该研究旨在描述这种改良的ESC技术随后进行PHT的定量和定性结果，并辨别ESC后PHT的最佳持续时间。次要目的是解决该技术对骨缺陷的影响。
包括在2017年至2021年间接受ESC和PHT的患者。病人性，手术年龄，手术持续时间,红细胞输血,住院时间,PHT持续时间,多个时间点的头颅指数（CI），并收集骨缺损信息。进行了描述性和相关分析。
31名患者（25名男性，6名女性）在研究期间进行手术。手术时的平均年龄为12.81周，平均手术时间为57.50分钟，平均输注红细胞体积为32cc，平均住院时间为1.84天,平均PHT持续时间为33.16周，平均随访时间为63.42周。平均术前CI为70.6，PHT结束时的平均CI明显更高，是77.1在22.97周，CI（CImax）出现最大改善。在最后一次随访时，PHT持续时间与CI无相关性。没有骨骼缺陷。
改良的ESC技术在成功矫正矢状颅骨融合中是有效的。CImax已经发生了，虽然PHT仍在继续，但是dishelmeting没有确定的时间点。该技术避免了骨缺损和不完全骨化。
