Abstract
Several procedures have been described for correction of orthognathic deformities of the mandible. Currently, the bilateral sagittal split osteotomy (BSSO) maintains its popularity because of its versatility and its amenability to rigid fixation techniques. The distal segment of the mandible can be repositioned in all planes of space, and the bony interface along the osteotomy results in predictable healing. However, there are well-known disadvantages to the procedure, which include neurosensory disturbance, 1 Pratt CA Labial sensory function following sagittal split osteotomy.
