Abstract An instrument for treating sinusitis enabling the introduction of one end of a plastic tube into a maxillary sinus and anchoring it there for successive irrigations distributed over a period oftime. Said end of the plastic tube (4) is provided with an arcuate bend for securing after introduction. Introduction is made by entering the tube into the lumen of a cannula (1), whereby the arcuate bend is elastically straightened. The sharp end (3) of the cannula (1) is introduced into the sinus, and the tube is then slid out with its said end into the sinus and regains its arcuate bend for securing, and the cannula is removed, the plastic tube securely remaining until purposely removed.
