研究目的:

主要研究目的:明确同期重建神经的新方法在腓骨瓣移植重建下颌骨中恢复下唇感觉及预防移植骨术后吸收的效能(移植骨骨块CT所测HU值降低率),进而提高术后生活质量,为改进颌骨大型缺损的功能性重建提供依据。次要研究目的:术后超声明确骨瓣血供情况,通过生活质量问卷等评估术后康复。为改进下颌骨大型缺损的功能性重建提供临床试验依据。  

Objectives of Study:

Primary research objective: To clarify the efficacy of new methods for simultaneous nerve reconstruction in fibula flap transplantation for mandibular bone reconstruction in restoring lower lip sensation and preventing post-transplant bone resorption (as measured by the reduction rate of HU values of the transplanted bone block on CT), thereby improving postoperative quality of life and providing a basis for improving functional reconstruction of large mandibular bone defects. Secondary research objective: To clearly determine the blood supply of the bone flap via postoperative ultrasound, and to evaluate postoperative rehabilitation through quality of life questionnaires, providing clinical trial evidence for improving functional reconstruction of large mandibular bone defects.

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:

本研究将使用本中心现有云服务器与临床研究一体化平台Medpro-EDC系统管理数据,对入组病例的去标识化影像、电生理、生活质量量表等数据进行实时上传、清洗与标准化。北大口腔、空军口腔两分中心被授予只读账号,可实时查看本中心及汇总统计图表,但无法导出可识别个人信息;如需跨中心联合分析,须由 DMC 与伦理委员会二次审批; 依据临床研究数据采集要求,搭建电子版CRF(eCRF)并进行逻辑校验。在首例受试者入组前完成eCRF的测试并上线使用。

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

This study will use the existing cloud servers and the clinical research integrated platform Medpro-EDC system of this center to manage data, and perform real-time upload, cleaning, and standardization of de-identified data such as images, electrophysiological data, and quality of life scales of enrolled cases. Peking University Stomatology Hospital and Air Force Stomatology Hospital, the two sub-centers, have been granted read-only accounts, allowing them to view real-time data of this center and aggregated statistical charts but not export identifiable personal information; cross-center joint analysis requires secondary approval by the Data Monitoring Committee (DMC) and the ethics committee. In accordance with clinical research data collection requirements, an electronic Case Report Form (eCRF) will be developed and subjected to logical validation. The eCRF will be tested and put into use before the enrollment of the first subject.
