A study of craniofacial asymmetry using computed tomography

: Cranio-facial dissymmetries especially concern orthodontics and orthognathic surgeons, but also all clinicians. A review of the conventional ways to study cranio-facial dissymmetries and their limits are presented. Progress of medical scanning allow to acceed to new methods of investigation and evaluation of cranio-facial morphology and dissymmetries. A cranio-facial dissymmetries analysis is suggested, based on CT, vestibular orientation, and an architectural and structural analysis, based on nervous indicators of the trigeminal nerve.
