Summary
Panfacial fractures are challenging for craniofacial surgeons. Aside from involving
multiple subunits, they also lack the reliability of a useful landmark of the facial
skeleton. Properly, reducing and fixing palatal fracture to re-establish the premorbid
maxillary dental arch is important. This was a retrospective study conducted from
2015 to 2020. All patients underwent computed tomography (CT) scan for surgical planning
of orthognathic surgery due to either esthetic or occlusion concerns. The classification
of occlusion was recorded as class I, II, and III. The parameters measured on CT were
the distance between the midpoint of the supra-orbital foramen/notch (IS), mesio-buccal
cusp tips (IB), central fossa (IC), palatal cusp tips (IP), and the midpoint of the
palatal marginal gingiva (IM) of the bilateral maxillary first molars. The IS was
compared with the IB, IC, IP, and IM. The results were analyzed by using one-way repeated
measurement analysis of variance.
Eighty-seven patients (36 men and 51 women) were included in the study. There were
13 patients of class I malocclusion, 8 of class II malocclusion, and 66 of class III
malocclusion. The IS was comparable to the IC in all three groups. The IS can predict
the IC, regardless of the patient's occlusion, and can be subsequently used to decide
the width of maxillary dental arch in panfacial fracture management. Further studies
are necessary to obtain more definite results.
