Figure 8. Examples of yaw in mandibular asymmetry.

Figure 8

Inferior view of mandibular models for 6 patients with the blue line marking the midsagittal plane location. Note the various degrees and direction of rotational asymmetry in the yaw of the mandible. If the asymmetric yaw of the mandible is not taken into account and virtually corrected prior to the use of mirroring techniques, mirroring techniques will yield misleading diagnosis of asymmetry. Asymmetry in the yaw orientation of the mandible would lead to undesirable results if surgical correction corrects chin position with genioplasty but does not properly correct asymmetry in the mandibular corpus and rami.
