Cephalometrics: a comparison of five analyses currently used in the diagnosis of dentofacial deformities

Wylie/Fish/Epker

There are presently a number of cephalometric analyses that are used in the assessment of dentofacial deformities. This paper compares five such analyses in ten individuals with dentofacial deformities who underwent variable surgical corrections. Pretreatment cephalometric radiographs of these ten patients were specifically selected to illustrate different dentofacial deformities, each of which was corrected by a different type of surgical procedure. Teh pretreatment cephalometric radiographs were blindly assessed by one investigator, who used the criteria for each of the five analyses. The results of these analyses(diagnoses) were then compared to on another and with the actual surgery that was performed, on a blind basis by a second investigator. When compared against one another with regard to the specificity of the diagnosis for each patient, the analyses showed considerable inconsistency. Seldom did all analyses result in the same diagnosis. When the diagnosis of the various analyses were then compared with the surgery performed, no single analysis agreed with the actual treatment performed more than 60% of the time. This information is consistent with the contention that cephalometrics cannot be considered as the primary diagnostic tool in the correction of dentofacial deformities.
