Anthropometric guidelines in cranio-orbital surgery

Surface measurements and proportions of the cranio-orbital region provide valuable information to the surgeon both before and after surgery. They supplement the data obtained from x-ray cephalometry. Preoperatively, the proportion indices help to identify the most deformed areas and reveal which measurements contribute to the disproportion. When surgery is being planned, the defective measurements help the surgeon to calculate the changes necessary. After surgery, the quality of proportionality achieved permits assessment of the degree of improvement.
