摘要:

背景:下颌支矢状骨劈开是矫治下颌骨畸形应用最为广泛的一种方法,最初提出的改进方法大多是依据临床的观察和经验,可用于下颌支矢状骨劈开借鉴的解剖数据非常有限,近20年来,此类解剖学研究日渐增多。
目的:全面了解与下颌支矢状骨劈开相关的下颌支的形态学研究的方法,明确目前下颌支矢状骨劈开术相关研究的进展。
方法:电子检索中国生物医学文献数据库和计算机Medline数据库1991至2011年收录相关综述和论文报告,并分析下颌支矢状骨劈开相关研究的进展。
结果与结论:共纳入下颌支矢状骨劈开相关文章共计26篇。与下颌支矢状骨劈开骨切开位置密切相关的下颌小舌区域骨松质的分布情况、与劈开过程相关的下颌管与颊侧骨皮质之间骨松质的分布以及与固定过程相关的下颌管在角部及角前部的定位和走向,是下颌支矢状骨劈开避免并发症的关键问题。针对下颌支矢状骨劈开手术过程,制定出术前CT检查的具体项目,依据所测量的数值指导临床操作,有助于手术的顺利进行并减少并发症的发生,使解剖学测量的基础研究能更大程度地应用于临床。

Abstract:

BACKGROUND: Sagittal split ramus osteotomy is one of the most popular surgical procedures for correcting various mandibular deformities. There have been numerous modifications to this technique on the basis of clinical experiences and observation, but relevant anatomical data are very limited. A lot of anatomic studies on the mandible have been performed during the recent 20 years.
OBJECTIVE: To entirely understanding the morphology of the mandibular ramus in the sagittal split ramus osteotomy and to explore the research progress in the sagittal split ramus osteotomy.
METHODS: An electronic search of CMB and Medline was performed for relevant reviews and papers published from 1991 to 2011. Progress in the sagittal split ramus osteotomy was also analyzed.
RESULTS AND CONCLUSION: Totally 26 articles related to the sagittal split ramus osteotomy were enrolled. The keys to avoiding complications due to the sagittal split ramus osteotomy are as follows: distribution of cancellous bone in the mandibular uvula area, distribution of cancellous bone between the mandibular canal and buccal cortical bone during splitting progress, as well as location and trend of the mandibular canal. Pre-operative CT test contributes to a successful sagittal split ramus osteotomy and a reduction in complications, and the anatomical measurement can be applied clinically to a greater extent.
