Abstract
The maxillary excretory function test attributable to the preoperative determination of pathological changes in maxillary mucosa and to the determination of therapy has been studied from the points of view of the selection of contrast medium, of the administration technique of it, of the excretory time of it, and of the method of photography.
From the discussion on some problems of maxillary excretory function test such as a classification of photograms etc., it is recognized that Daito's method using the highly concentrated contrast media is most valuable in clinical practise.
Moreover, by the detailed investigation of the diagnostic and the therapeutic significance, the author has known that this method which has a direct relation to the ciliary function of impaired sinus mucosa and to the pathological mucous thickness has a further qualitative and quantitative significance on the sinusitis of which diagnosis has not been reliable and precise.
