Abstract

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.
