I measured with a planimeter X-ray images of Pneumatic cells of temporal bones which were taken by Sonnenkalbs method before the endoaural operation of the middle ear on 20 cases at the Department of Oto-Rhino-Laryngology, Yokohama University School of Medicine from May, 1952 to the end of December, 1956. Then I analysed the relations between the results of the above measurement and the epit-helisation of the middle ear cavity after the operation, and found that so far as my cases are concerned, the endoaural operation of the middle ear can be successfully applied when the area of pneumatic cells is less than 9 cm2.
