The treatment of nasal sinusitis has been considerably enhanced by the introduction of displacement irrigation by Arthur W. Proetz, of St. Louis.1 In like fashion, valuable diagnostic details have been made available by displacement filling of the sinuses with radiopaque fluids.

The dropper and the suction tip are alternately applied to the nostrils until the procedure is completed.
