Diagnostic significance of puncture and trepan biopsy of salivary gland tumors under ultrasound control and its reliability in doubtful situations

Aim. To ascertain the diagnostic reliability of puncture and trepan biopsy of salivary gland tumors under ultrasound controlMaterials and Methods. The study included 26 patients diagnosed with benign tumors and 16 patients with malignant tumors of the salivary glands. To determine the final diagnosis, a cystology test was conducted using the Romanov Giemsa staining method on the materials. Histological examinations were stained using the hematoxylin-eosin technique.Results and Discussion. All 42 patients (100% of cases) with salivary gland tumors were divided into two groups based on the morphological features of their tumors: Group I comprised 20 patients (47.6% of cases) from a retrospective study conducted from 2013 to 2016, and Group II encompassed 22 patients (52.4% of cases) from a prospective study conducted from 2017 to 2020. Our uniquely developed method of puncture and trepan biopsy under ultrasound control demonstrated that the results derived from this approach closely aligned with those obtained from incisional and excisional biopsies. This correspondence underlines the successful diagnosis and treatment of patients with benign and malignant tumors of the salivary glands.Conclusion. The method of puncture and trepan-biopsy under ultrasound control exhibits high diagnostic reliability in confirming cells of benign and malignant tumors of the salivary glands, thereby eliminating the need for incisional and excisional biopsy of these tumors in subsequent treatment strategies. In Group I, the discrepancy between the investigative methods was 35%, while in Group II, which employed our method of puncture and trepan biopsy under ultrasound control, no inconsistency was observed.
