Growth of Interorbital Distance and Skull Thickness as Observed in Roentgenographic Measurements

Abstract

Percentile standards for the measurements of interorbital distance and thickness of the skull based upon roentgenograms of the skull and paranasal sinuses in a group of healthy subjects are presented. The deviation of the pattern of growth is analyzed. Two applications of the standards are demonstrated: Down''s syndrome in a 35-year-old woman; and a benign form of osteopetrosis in a 37-year-old man presented with data concerning his brother and offspring. The age ranges for the closure of cranial sutures are discussed.
