研究目的:

本研究由两个相对独立又相互关联的部分构成,旨在从临床观察到基础机制,系统探讨 Lefort I型截骨术后的愈合问题。 第一部分:单中心、回顾性队列研究 目的: 分析 LeFort I 型截骨患者术后骨愈合及稳定性与上颌骨游离骨块移动方向、距离、术中是否植骨及植骨方式等因素的相关性。 第二部分:单中心、前瞻性、观察性研究 目的:定期拍摄 CBCT 观察行清创术后的患者上颌骨软硬组织的改建情况;利用单细胞测序技术,描绘骨愈合不良区域炎性增生组织的细胞图谱与基因表达特征,阐明其对骨愈合微环境的潜在影响机制。  

Objectives of Study:

This study consists of two relatively independent yet interrelated parts, designed to systematically investigate the healing process following LeFort I osteotomy, transitioning from clinical observation to underlying mechanisms. Part 1: A Single-Center, Retrospective Cohort Study Objective: To analyze the correlation between postoperative bone healing/stability in patients undergoing LeFort I osteotomy and factors such as the direction and distance of maxillary free segment movement, the use of intraoperative bone grafting, and the specific grafting techniques employed. Part 2: A Single-Center, Prospective, Observational Study Objective: To periodically assess the remodeling of both hard and soft tissues in the maxilla post-debridement using CBCT imaging. Furthermore, to utilize single-cell RNA sequencing to characterize the cellular composition and gene expression profiles of inflammatory hyperplastic tissue in areas of compromised bone healing, thereby elucidating their potential mechanistic impact on the bone healing microenvironment.
