[18] Diagnostics for nerve damage consist of: brush-stroke directional discrimination (BSD), touch detection threshold (TD), warm/cold (W/C) and sharp/blunt discrimination (S/B), electrophysiological tests (mental nerve blink reflex (BR), nerve conduction study (NCS), and cold (CDT) and warm (WDT) detection thresholds.

The stability and predictability of orthognathic surgical procedures varies by the direction of surgical movement, the type of fixation, and the surgical technique employed, largely in that order of importance. The jawbones are repositioned to a more “normal” position; bone may be added, removed, or reshaped. The most stable orthognathic procedure is superior repositioning of the maxilla, closely followed by mandibular advancement in patients in whom anterior facial height is maintained or increased.
