FIELD: medicine; medical engineering.
SUBSTANCE: method involves introducing operation end of the device into middle nasal passage, turning it in lateral direction, feeling deepening and compliant place in the lateral surface of middle nasal passage funnel and the operation end is introduced into the maxillary sinus through natural anastomosis. The device has S-shaped tube, pavilion for attaching syringe and pelot having mutually perpendicular surfaces. Distal end of the S-shaped tube is thickened and has cross-marks for denoting depth to which the device is introduced. Hemispheric mark is soldered to one of pelot surfaces, its direction being opposite to tube operation end direction. The tube operation end is soldered and has lateral openings.
EFFECT: reduced risk of traumatic complications.
