Because of the existing interest in the treatment of sinus infections by means of the short wave current, we made observations of the changes of temperature occurring in the paranasal sinuses as a result of the application of this current.
The technic we employed consisted in the use of a condenser electrode cut out in the shape of a butterfly so as to cover the region of the frontal sinuses, nose and maxillary antrums and another condenser electrode applied to the upper part of the back or else placed on a wooden chair, permitting the patient to sit on it. We also employed a solid oblong condenser electrode placed over the area of the forehead, nose, eyes and cheeks. These electrodes were separated from the skin by means of felt pads and towels. The machines which we used produced oscillations of 50,000,000, 20,000,000 and 18,750,000 cycles (wavelengths of 6, 15
