Abstract: FIELD: medicine. 
     SUBSTANCE: joint sealing of the nasal cavity, nasopharynx and paranasal sinuses is performed. Periodically, the pressure in the nasal cavity is measured with creation of negative and positive pressure. Drugs are introduced into the nasal cavity after creation of negative pressure. At that, the damaged sinus is saturated with a drug solution after creation of negative pressure through the opposite half of the nose in nasal sinus position opposite the drain one, when its fistula plane is in the uppermost position in relation to the opposite wall or to the place of front and back walls joint, for the maxillary sinuses. Evacuation is performed in drain situation, when the sinus fistula plane is in the lowest position towards the opposite wall or to the place of front and back walls joint, for the maxillary sinuses. After the damaged sinus is filled with a drug solution, a mechanical effect is provided on the biofilms located on its walls, due to disturbance of the liquid in it by means of an air-hydraulic impact, which is carried out by injecting air into the affected half of the nose before opening of the auditory tubes, which is accompanied by a sensation of a "push" in the ears, with the closed vestibule of the opposite half of the nose pressing the wing of the nose to the nasal septum and raising the soft palate in the drain position of the sinus, and also due to the liquid movement in the sinuses, resulting from the use of liquid inertia forces in the paranasal sinuses by mechanical movements of the head with a sudden stop not directed towards the affected sinus fistula. Then the liquid is evacuated from the sinuses using the negative pressure created in the nasal cavity in the drain position of the affected sinus along with biofilms pieces and bacterial plankton. The method is implemented by a device that includes a tripod, movable locking bar, cylinder for solutions or air injection into the nasal cavity, embodied in the tripod between the movable locking bar and the fixed left side wall of the tripod. The cylinder for vacuum creation in the nasal cavity, fixed on the tripod between the movable locking bar and the fixed right-side wall of the tripod and olives with channels that are attached by tubes to the said cylinders. At that, the movable locking bar is made with a possibility of movement in two directions to the fixed right and left side walls of the tripod through the upper and lower guides placed in slots for guides in the upper and lower lids of the tripod, and implementation of alternated compression of these cylinders. In the second embodiment, the device comprises a tripod with holes in the side walls, a syringe for vacuum creation in the nasal cavity. A syringe for solutions or air injection into the nasal cavity and olives with channels, attached by tubes to the said syringes. At that fixation of the syringe cylinders in the holes of the side walls of the tripod, impeding their displacement during operation is provided by cylinder stops, so that the cylinder stops of the syringe for vacuum creation in the nasal cavity are located on the inner surface the left side of the tripod, and the cylinder stops of the syringe for solutions or air injection into the nasal cavity are located on the outer surface of the right-side wall of the tripod. And the syringe cylinders are located in opposite directions to be controlled by both hands. 
     EFFECT: method allows to increase the effectiveness of treatment of paranasal sinuses due to mechanical influence on drug solution biofilms and evacuation of biofilm particles, microbial plankton from the sinuses with the used solutions.
