AN APPARATUS FOR DISPLACEMENT IRRIGATION OF NASAL SINUSES

The treatment of nasal sinusitis has been considerably enhanced by the introduction of displacement irrigation by Arthur W. Proetz, of St. Louis.1In like fashion, valuable diagnostic details have been made available by displacement filling of the sinuses with radiopaque fluids. In performing displacement irrigation and filling by Proetz' technic, many operators employ a medicine dropper to introduce various solutions into the nose. The vacuum phase of the procedure is then carried out by applying the tip of a sinus suction bottle to the nostril, the bottle being connected to a suction pump or to some other device for producing negative pressure. The dropper and the suction tip are alternately applied to the nostrils until the procedure is completed. This method for the introduction of fluid and suction has its drawbacks.
