This book describes a method of cephalometric evaluation of the craniofacial complex. Although the cephalometric analysis is inspired by the counterpart principle of Enlow, certain parameters in the vertical evaluation of the craniofacial complex as described in this book are different and cannot be found in many books on cephalometrics or orthodontics. Also, several additional ratios have been established for sagittal evaluation. All the measurements in this book are expressed as ratios. The inclination of cranial base is the only angular measurement evaluated. The sagittal and vertical segments, the facial heights, the facial depth are some of the parameters described and measured in this book. The book also elaborates on the segments of the craniofacial complex that are in dimensional balance and those that are in imbalance.
