研究目的:

通过多中心随机对照试验,比较局麻下腭中缝全层劈开术联合种植钉辅助扩弓(试验组)与全麻下上颌Lefort I型截骨正中劈开术辅助扩弓(对照组)的上颌骨性扩弓效率,以评价局麻下腭中缝劈开术联合种植钉的骨性扩弓疗效,及其替代传统全麻Lefort I型截骨正中劈开术辅助扩弓用于治疗成人上颌骨宽度发育不足的可行性。  

Objectives of Study:

A multicenter randomized controlled trial was conducted to compare the efficacy of maxillary expansion assisted by full-thickness midpalatal suture splitting under local anesthesia (trial group) with that assisted by median split under Lefort I osteotomy (control group), and to evaluate the efficacy of maxillary expansion assisted by full-thickness midpalatal suture splitting under local anesthesia (control group). The aim of this study was to evaluate the feasibility of maxillary expansion as an alternative to traditional Lefort I osteotomy combined with median split general anesthesia in the treatment of adult maxillary deficiency.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

整个试验过程严格执行临床试验质量管理规范,所有纸质CRF记录完整、真实、清晰、客观后将试验数据输入计算机,锁定数据后储存。 病例报告表填写与移交 病例报告表(CRF)由研究者填写,每位入选病例必须完成病例报告表。完成的病例报告表由监查员审查后,第一联移交数据管理员,进行数据录入与管理工作,第一联移交后,病例报告表的内容不再做修改。记录员收集存储所有受试者术前设计方案及术后影像数据,完成模型匹配。所有修改过的数据和原数据及修改人、修改日期和修改原因等都将作记录保存。记录员完成所有受试者次要评价指标记录。 数据录入与修改 数据管理员釆用软件编制数据录入程序,进行数据录入与管理。为保证数据准确性,应由两位数据输入员独立进行双份录入并校对。对病例报告表中存在的疑问,数据管理员将通过产生疑问解答表(QF, Query Form)向研究人员发出询问,并通过监查员联系研究人员在24h内解答并返回:数据管理员根据研究人员的回答进行数据修改、确认与录入,必要时可以再次发出QF。对数据核查中发现的任何疑问,由数据管理员汇总,并产生疑问解答表(DRQ),及时交给临床监查员,由监查员向研究者进行质询,对问题限期纠正,并提交改正后的资料。临床研究者在接到数据疑问后1周内就疑问表的问题进行答疑并反馈数据管理员。若超出时限,则将疑问反馈到上一级课题负责人。数据库管理人员在收到数据疑问表答疑后,对数据进行确认与录入,在2日内对数据库数据进行修改。 数据库锁定 在数据审核并确认建立的数据库正确后,由数据管理人员、主要研究者、统计分析人员、申办者和监查管理人员共同对数据进行审核,并完成分析人群的最后定义及判断,之后由数据管理员对数据库进行锁定。锁定后的数据库或文件一般情况下不得再做改动。 数据处理 数据库锁定后提交统计分析人员进行统计分析。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

The whole trial process strictly implemented the good clinical practice quality management, all paper CRF records were complete, true, clear and objective, the trial data were input into the computer, and the data were stored after locking. Case report form completion and handover The case report form (CRF) was completed by the investigators and was mandatory for each enrolled patient. After the completed case report form was reviewed by the monitor, the first link was transferred to the data manager for data entry and management. After the first link was handed over, the content of the case report form was not to be modified. The recorder collected and stored the preoperative design scheme and postoperative image data of all subjects to complete the model matching. All the modified data and original data, as well as the modified person, the date of modification and the reason for modification, will be kept for record. The recorder completed all the secondary evaluation indicators of the subjects. Data entry and modification The data manager used software to compile the data entry program for data entry and management. To ensure the accuracy of the data, two data entry staff should enter and proofread the data in duplicate independently. If there are any questions in the case report Form, the data manager will send questions to the researchers through the Query Form (QF), and the monitor will contact the researchers to answer and return them within 24 hours. The data manager will modify, confirm and enter the data according to the answers of the researchers, and the QF can be issued again if necessary. Any questions found in the data audit were summarized by the data manager, and a question answer form (DRQ) was generated. The DRQ was sent to the clinical monitor in time, who questioned the researchers, corrected the problems, and submitted the corrected data. Clinical investigators answered questions on the query form and provided feedback to the data manager within 1 week after receiving data queries. If the time limit was exceeded, the question would be fed back to the next level project leader. After receiving the data query form and answering questions, the database management personnel confirmed and entered the data, and modified the database data within 2 days. Database locking After data review and confirmation that the established database was correct, data managers, the principal investigators, statistical analysts, the sponsor, and monitoring managers reviewed the data and made the final definition and judgment of the analysis population, after which database locks were made by data managers. A locked database or file should generally not be changed. Data processing The database was locked and submitted to the statistical analyst for statistical analysis.
