Cephalometrics is no panacea, alone or in conjunction with other records. An appraisal of cephalometrics and its limitations is probably the need of the hour. The deficiency of cephalometrics starts at the very beginning that is in the head positioning. Landmark definition is the biggest Achilles heel of cephalometrics. With the lack of clarity in landmark definition, identification and error in location having not been fully addressed, the actual problem arises since it these same landmarks which are used to construct planes and angles. The problem compounds with the description of some of the planes used for analysis being, at best, vague. In our view, however, the biggest disadvantage of cephalometrics is the limited acceptance of the racial variation in various measurements and how this has not been duly factored into the clinical diagnosis. The less said about the myriad of cephalometric analyses available and their contradictions. This begs the questions which of these analyses are more reliable. Thus, in conclusion, inspite of these limitations listed and noted for more than 50 years, cephalometrics, particularly lateral cephalometric radiography, though strictly not an essential diagnostic aid, continues to be popular and serves the clinical orthodontist with additional and what appears to be as essential and invaluable data.
