Despite the fact that otorhinolaryngologists are already very busy finding a solution to the problem of chronic tonsillitis, it remains unresolved. The prevalence of chronic tonsillitis does not decrease, but rather increases. Diseases of the tonsils are characteristic primarily of the child and adult working population. Chronic tonsillitis attracts attention not only as an independent disease, but as a cause of frequent local and especially systemic complications, which number more than 100. All these facts speak about the unresolved and urgency of the problem of chronic tonsil disease. In the diagnosis of neck diseases, one of the most common methods is ultrasound. It has a number of significant advantages over other methods, such as high sensitivity and specificity, the ability to detect minor changes in the organs, non-invasiveness of the study, painlessness, accessibility, and the absence of ionizing radiation. The aim of the literature review is to identify, analyze, and systematize literature data on the application of the ultrasonic research method in neck organ pathology. Ultrasound diagnostics in the neck is widely used and is actively studied in acute inflammatory-purulent pathology (paratonsillar abscesses, phlegmon), in the pathology of the larynx and trachea, salivary and thyroid glands, as well as in the metastasis of malignant neoplasms to the lymph nodes. There are several methods for diagnosing lymph nodes, such as: puncture and excision biopsy, lymphography, scintigraphy, thermography and ultrasound ultrasound. Despite such a variety of diagnostic methods, ultrasound is the method of choice for imaging cervical lymph nodes. One of the most modern methods in ultrasound diagnostics is elastography. This method is most informative in cases when changes in tissues are small in size and cannot be detected using standard ultrasound modes.

ель исследования. Изучение критериев ультразвукового исследования с контрастным усилением у пациентов с патологией лимфатических узлов шеи, в сопоставлении с результатами морфологической верификации. Материалы и методы. Ультразвуковое исследование с контрастным усилением (КУУЗИ) проведено 32 пациентам с патологией лимфатических узлов (ЛУ) шеи, с последующей морфологической верификацией. Результаты и обсуждение. Качественные показатели КУУЗИ отличаются при исследовании ЛУ шеи с доброкачественным и злокачественным поражением. Статистически значимыми оказались количественные критерии: нулевое время-T0, пик интенсивности-PI. Злокачественное поражение ЛУ шеи выявляется при превышении пограничных значений PI=8,6 дБ (чувствительность=77,0%, специфичность=92,0%), при меньших значениях T0=6,4 с (чувствительность=81,0%, специфичность=85,7%). Графическое представление ROC-кривых показывает хорошее качество модели, площадь под кривой (AUC) T0 составила 0,861; PI-0,876. Заключение. КУУЗИ с качественным и количественным анализом возможно использовать в дифференциальной диагностике при патологии лимфоузлов шеи. Ключевые слова: ультразвуковое исследование, ультразвуковое исследование с контрастным усилением, ультразвуковой контрастный препарат, лимфатический узел, метастазы.

Purpose of the study. To assess ultrasound features and patterns of features for metastatic papillary thyroid cancer (PTC) in soft tissues of the neck.Materials and methods. The study included 335 histologically confirmed metastases and 102 benign lymph nodes (LN). Statistical processing was carried out in the SPSS program. The reliability between the groups was assessed by criterion t with a significance level of p < 0.05. The informative value of ultrasound signs and patterns of signs, and the probability of the presence of metastasis using binary logistic regression are calculated.Results. The 14 criteria for metastasis have been studied. There are 33 signs, i.e. types of criteria. During the statistical analysis, six most informative criteria were established: calcifications, contours, shape, depth-to-width ratio in the transverse scanning plane, state (differentiation) of the cortical and cerebral layers, echostructure. To create complexes (patterns) of ultrasonic signs, a combination of these signs was used among themselves, and five patterns were established. The first pattern, including the depth-to-width ratio in the transverse scanning plane and the echo structure, has a sensitivity (Se) of 97 %, diagnostic accuracy (Ac) of 96.5 %, area under the curve (AUC) of 96 %, the probability ranges from 95 to 99 %. The Se of the second pattern, including the ratio of depth to width in the transverse scanning plane, echostructure and shape, was 97.2 %, Ac – 96.8 %, AUC – 97.3 %, probability – 95–100 %. The third pattern, including the ratio of depth to width in the transverse scanning plane, nature, shape and contours, and the fourth pattern, including the following criteria, the ratio of depth to width in the transverse scanning plane, echostructure, shape, contours and differentiation into cortical and cerebral layers, have Se 96.9 %, Ac – 97.1 %, AUC – 98.7 %, probability – 88–100 %. The fifth pattern, including the ratio of depth to width in the transverse scanning plane, echostructure, shape; contours; state (differentiation) of the cortical and cerebral layers; calcinates, has Se – 99.6 %, Ac – 99.5 %, AUC – 99.9 %, probability – 94–100 %.Conclusion. Five patterns of metastatic involvement of lymph nodes in PTC were found. The informative value of US increased from the first to the fifth pattern achieving a Se of 99.6 %, Ac of 99.5 %, AUC of 99.9 %. The probability ranged from 94 % to 100 %.
