[Analysis for diagnosis of developmental maxillofacial anomalies in Mexico city residents].

Most cephalometric analysis published to date are based on studies performed by orthodontists, focused on individuals in the growth and development stages, and based mainly on individuals with morphogenetic patterns different from those of the Latin prototype. Such studies concede little attention, if any, to the evaluation of the median (middle) third, which makes them insufficient to amply determine sites of structures found in this area of the face. In Mexico, the maxillofacial surgeon often needs to analyze individuals at the end of their growth stage, with very varied morphogenetic patterns, a result of wide ethnic interbreeding. This preliminary study aims to attain an analysis applicable to Latin individuals, whose morphogenic pattern tends toward the Caucasian prototype, and to establish standards from which to evaluate the middle third.
