We have applied morphometry on formaldehyde-fixed, H & E-stained diagnostic laryngeal biopsies from 7 patients with mild dysplasia and 7 with severe dysplasia/carcinoma in situ, in search of objective parameters required for reproducible histopathological grading of epithelial dysplasias. Special emphasis has been put upon the individual nuclear polarity as a spatial variable. Also included were 4 specimens with normal epithelium. By means of a semiautomatic digitizing tablet, the nuclear and epithelial area, formfactor and the polarity variation between the longitudinal axes of adjacent nuclei were measured in the basal, parabasal, middle and luminal layers of the epithelium. N:C-ratio, mean values of nuclear area, formfactor or their coefficient of variation could not distinguish between mild and severe dysplasia. The variations in neighboring nuclear polarity, however, revealed a highly significant distinction between mild and severe dysplasia (p less than 0.001). This parameter may therefore have diagnostic potential.
