METHOD FOR DIFFERENTIAL DIAGNOSIS OF VARIOUS STAGES OF MAXILLOFACIAL LYMPHEDEMA USING ULTRASOUND METHOD Russian patent published in 2022 - IPC A61B8/08 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely, oncology, functional diagnostics, and can be used in the differential diagnosis of various stages of lymphedema. To do this, an ultrasound examination of the tissues of the zone of the pathological focus of the maxillofacial region and the area of adjacent tissues in a radius of at least 30 mm is performed, and tissues are scanned in a similar zone on the contralateral “healthy” side. The following diagnostic parameters are determined: tissue thickness, the presence of tissue differentiation disorders in relation to the following layers: skin, subcutaneous fat, fascia, muscles; echogenicity of tissues; presence or absence of dilated lymphatic vessels; state of microcirculation by color Doppler mapping. The ultrasound data obtained is compared with the contralateral side and, based on the comparison, the stage of lymphedema is determined.

EFFECT: method provides an accurate differential diagnosis of lymphedema of the maxillofacial region through the use of ultrasound scanning in the area of lymphatic drainage disorders with the assessment of tissues by objective indicators, as well as comparative analysis with similar indicators determined on the contralateral “healthy” side.
