Morphologic characteristics of the mandibular ramus in patients with prognathism undergoing sagittal split ramus osteotomy / 中国组织工程研究

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:Total y 26 articles related to the sagittal split ramus osteotomy were enrol ed. The keys to avoiding complications due to the sagittal split ramus osteotomy are as fol owsdistribution of cancel ous bone in the mandibular uvula area, distribution of cancel ous bone between the mandibular canal and buccal cortical bone during splitting progress, as wel 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 clinical y to a greater extent.
