“…The establishment of a universal list of repeatable landmarks could help to determine and evaluate linear, angular and proportional measurements. This list could also enable the inclusion of volumetric and surface measurements in 3D cephalometry, which could be helpful in airway or orbital volume analysis for syndromic or post-injury deformities (Imai et al, 2013;Kwon et al, 2009;Nout et al, 2012), as well as in soft tissue surface analysis for orthognathic surgery (Meller et al, 2005;Xia et al, 2000). The theoretical considerations could further include a combination of 3D cephalometry and finite element analysis, which could allow for more accurate prediction of the effects of surgical distraction or orthodontic expansion (Araugio et al, 2013;Remmler et al, 1998).…”
