[Computer tomographic volume determinations of the pneumatised portions of the ear (author's transl)].
A method for the volumetric measurement of the pneumatized parts of the ear by computer tomography is described. The boneair boundaries are determined by density measurements. The appropriate slices produce values which are automatically added under optical control. Thirty-four normal and abnormal ears have been examined in this way. The greatest air volume observed was 12.9 ml., the smallest 0.0 ml. The volumes are related to age and provide information concerning various types of disease.
