When using an osteotome (as opposed to a technique using a spreader) for bilateral
sagittal split osteotomy, it is important to separate the buccal cortex from the intramedullary
bone (involving the inferior alveolar neurovascular bundle) before the split by twisting
the osteotome).

A thin sharp osteotome is usually malleted into the groove created on the buccal
shelf, and the junction is separated in advance. During malleting, particular care
should be taken not to damage or transect the neurovascular bundle because it is close
to this junction, and the buccal shelf is narrow. Braces on the buccal side of the
teeth will occasionally obstruct the desirable insertion of the blade. To deal with
such situations, I have introduced a modified osteotome and have obtained satisfactory
outcomes.Keywords
