DIAGNOSTIC TECHNIQUE FOR MAXILLARY SINUSITIS IN PREGNANT PATIENTS Russian patent published in 2024 - IPC A61B1/233 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly to otorhinolaryngology, and can be used for diagnosing acute maxillary sinusitis (AMS) in pregnant patients. If observing signs of developing acute maxillary sinusitis, the females are examined using a digital diaphanoscope. Light-emitting diode applicator is placed in the patient’s oral cavity. Following parameters are set: optical power 35-40 mW for 650 nm and 25-60 mW for 850 nm, camera exposure time 40 ms. Light scattering patterns are recorded with a CMOS camera at wavelengths of 650 nm and 850 nm and an intensity parameter (IP) is calculated for the left and right sides of the face separately. If the IP value is 50% and less, AMS is diagnosed.

EFFECT: method provides fast, safe diagnostics of AMS for patients at any stage of pregnancy due to application of digital diaphanoscope and further analysis of light scattering pattern with CMOS camera at wavelengths 650 nm and 850 nm.
