CHAPTER VI Treatment of Focal Infection of the Throat by X-Ray Compared with Surgical Removal of Tonsils and Adenoids The x-ray method of treating chronic focal infec-tion of the throat, namely, tonsils and adenoids, isnot only safe and permanent, but will more thor-oughly and completely remove this focal infectionthan any other method yet devised, surgical orotherwise, and furthermore, the contraindicationsfor operation in no way interfere with this pro-cedure. The technic is comparatively simple. In theaverage case we use a seven-inch spark gap, fivemilliamperes, four minutes time, ten-inch distance,and three mm. of aluminum as filter.

A special tableand board have been devised for the treatmentof children. The principle upon which this method is basedmight be stated as follows: Both lymphatic andembryonic tissues are more easily destroyed bythe x-ray than any other living cell. The tonsilconsists mainly of lymph tissue. The small fibroidtonsil so commonly associated with rheumatismcontains lymph follicles, the greater part of whichis embryonic tissue as evidenced by the mitoticfigures. The embryonic tissue in the follicles ofthe large lymph tonsil is considerably less than isfound in the fibroid tonsil. The rem
