Self-tubotympanic instillation according to Niosi-Laskiewicz (STTI) is an original technique by means of which medicated drops are introduced into the middle ear cavity. Resort to the said technique was strictly limited for many years by its proposer himself due to the doubt of possible non physiologicity of the course of drops. But, in the long run, the uneventful use of such a device pushed it once more on the stage. The patient undergoing (and learning) STTI, lies supine, his head resting on a pillow whose swelling assures about 30° leaning on the plane of the bed. Head has to be inclined 45° on the side under treatment thus creating a slope along which medication will slide down into the tube. A blunt dropper, charged with 1 mL of drops, is introduced into the nostril corresponding to the ear under treatment. Before squeezing the dropper the physician asks his patient to open his mouth widely as for a yawn. “Yawn” has to be mantained all along instillation. Slowness of delivery is recommended. By means of STTI were given the following medications: steroids, fibrolytics and mucolytics as streptokinase and streptodornase, polyphosphoesters and antibiotics. Actual entrance of drops into the tube was proved by radioisotopic technique. Thus the first scintigraphic image of middle ear cavity was recorded by the medical literature.
