| abstract |
A method for using a surgical apparatus that permits invisible and permanent drainage and aeration of chronically affected sinus passages in children and adults is disclosed. The apparatus is made of flexible plastic material, preferably of silicon or polyethylene. T-shaped wings located at the two extremities of a tube permit the apparatus to be held in position after insertion and to be with- drawn by means of pliers. The size of the aerator, its length and its wings can vary according to the age of the patient, the respective illness and the requirements of endoscopic control. Positioning of the aerator is accomplished by means of a delivery device in which the aerator is inserted with its wings folded. The aerator is pushed by means of a mandrel into the sinus up to a stop, whereupon the internal wings deploy; at this point it is necessary only to withdraw the delivery device to have the aerator in place. |
