A method for 3-D cephalometric analysis of a patient to plan treatment and to track patient progress at different stages of ongoing treatment, the method executed at least in part on a computer processor and comprising: displaying reconstructed volume image data from a computed tomographic scan of a patient's head from at least a first 2-D view or a 3-D view; accepting (S200, S210, S220, S230, S240, S250) an operator instruction that positions and displays at least one reference mark on at least the first displayed 2-D view or the 3-D view; segmenting one or more dentition elements within the mouth of the patient; computing (S106, S108) and displaying a plurality of cephalometric parameters and a plurality of derived cephalometric parameters for the patient according to data from the at least one reference mark and the one or more segmented dentition elements; computing, using the computed cephalometric parameters, one or more results indicative of maxillofacial asymmetry; and energizing a graphical or text display to show the computed results indicative of maxillofacial asymmetry, wherein the display includes: a first plurality of entries representing different selected maxillofacial asymmetric anterior posterior relations, maxillofacial asymmetry vertical relations and maxillofacial asymmetry transverse relations, a second plurality of entries representing synthesized maxillofacial asymmetric cumulative anterior posterior condition, synthesized maxillofacial cumulative asymmetric cumulative vertical condition, and synthesized maxillofacial asymmetric cumulative transverse condition, which are generated using the first plurality of entries, and based on the second plurality of entries, a third entry representing a combination of the synthesized maxillofacial asymmetric cumulative anterior posterior condition, the synthesized maxillofacial asymmetric cumulative vertical condition, and the synthesized maxillofacial asymmetric cumulative transverse condition. displaying reconstructed volume image data from a computed tomographic scan of a patient's head from at least a first 2-D view or a 3-D view; accepting (S200, S210, S220, S230, S240, S250) an operator instruction that positions and displays at least one reference mark on at least the first displayed 2-D view or the 3-D view; segmenting one or more dentition elements within the mouth of the patient; computing (S106, S108) and displaying a plurality of cephalometric parameters and a plurality of derived cephalometric parameters for the patient according to data from the at least one reference mark and the one or more segmented dentition elements; computing, using the computed cephalometric parameters, one or more results indicative of maxillofacial asymmetry; and energizing a graphical or text display to show the computed results indicative of maxillofacial asymmetry, wherein the display includes: a first plurality of entries representing different selected maxillofacial asymmetric anterior posterior relations, maxillofacial asymmetry vertical relations and maxillofacial asymmetry transverse relations, a second plurality of entries representing synthesized maxillofacial asymmetric cumulative anterior posterior condition, synthesized maxillofacial cumulative asymmetric cumulative vertical condition, and synthesized maxillofacial asymmetric cumulative transverse condition, which are generated using the first plurality of entries, and based on the second plurality of entries, a third entry representing a combination of the synthesized maxillofacial asymmetric cumulative anterior posterior condition, the synthesized maxillofacial asymmetric cumulative vertical condition, and the synthesized maxillofacial asymmetric cumulative transverse condition. a first plurality of entries representing different selected maxillofacial asymmetric anterior posterior relations, maxillofacial asymmetry vertical relations and maxillofacial asymmetry transverse relations, a second plurality of entries representing synthesized maxillofacial asymmetric cumulative anterior posterior condition, synthesized maxillofacial cumulative asymmetric cumulative vertical condition, and synthesized maxillofacial asymmetric cumulative transverse condition, which are generated using the first plurality of entries, and based on the second plurality of entries, a third entry representing a combination of the synthesized maxillofacial asymmetric cumulative anterior posterior condition, the synthesized maxillofacial asymmetric cumulative vertical condition, and the synthesized maxillofacial asymmetric cumulative transverse condition.
