Patients should now be informed of the benefits of the use of a piezoelectric saw before orthognathic bilateral sagittal split osteotomy

Since the Montgomery ruling1, surgeons have had to widen the scope of consent to include any information that could be of material interest to patients before a procedure. Orthognathic patients who have had bilateral sagittal split osteotomy have traditionally been warned about high rates of permanent change of sensation to the lower lip or chin, and recent multicentre data from the UK has identified a self-reported rate of change of sensation of 56%.2
