Bone thickness and split pattern in mandibular osteotomies

This paper looked at 63 sagittal split ramus osteotomy sites. The type of split was classified according to the Plooij paper and bone measurements were taken at four sites. Of these sites, the thickness of the bone in one point,...

Hierarchy of orthognathic surgical stability

This study was designed as ‘an overview’ of secondary studies and analysed 15 articles. Two procedures were considered highly unstable, a bilateral sagittal split osteotomy for clockwise rotation of the mandible with bi-cortical screw rigid internal fixation, and posterior maxillary...

Tranexamic acid and blood loss in bimaxillary surgery

This is a randomised, double blind, placebo-controlled trial from Thailand to clarify the most effective dose of Tranexamic acid in reducing blood loss during a bimaxillary osteotomy. They confirmed that the dose of 10mg per kg is the most efficacious...

Bad splits

This is a meta-analysis of reported risk factors of a ‘bad split’ in a sagittal split mandibular osteotomy. They identified 30 observational articles and therefore acknowledged it is based on low quality studies. It is compounded by the definition of...
