Traditionally, orthodontists used posteroanterior cephalogram to diagnose transverse deficiency. This method presents a major inconvenience because of the superimposition of very distinct anatomical structures and the lack of precision in landmark identification. Because of the aforementioned problems, we decided to use intersection points between structures. The drawback in using the latter is that there can be projection errors if there is an inclination or head roll. Aim: The study’s purpose was to identify craniometrical points in order to perform a reliable transverse diagnosis. Methodology: We performed a systematic review of the existing literature (between 2000-2017) in four databases: PubMed, Embase, Cochrane and Scopus using the following key words: “Cone Beam Computed Tomography” AND “Jaw” Mesh terms. Results: After removing duplicates, we obtained 1,322 papers, of which we chose just 43 abstracts for analysis. Finally, using inclusion criteria, there were no published articles meeting the aforementioned parameters. Conclusion: It is very difficult to strictly define craniometrical points.  (Rev Esp Ortod. 2017;47(2):073-078)
