Radiophotoscanners are relatively new diagnostic tools. They provide visual images as well as quantitative information about the behavior in the human body of special substances called radionuclides. This paper is a preliminary report about the use of a radioactive gas, 133 Xenon, to study the ventilation of the middle ear and sinuses. This technique has so far rendered intriguing, and at the same time, fascinating results. At this point in time these results cannot be considered definitive or conclusive. It is conceivable, however, that if standardization and control of variables is achieved, this technique may play an important role in the physiological and pathological assessment of these cavities.
