In this study, we aimed at comparing the adequacy of conventional spread and liquid-based cytology (SBS) methods in thyroid thin injection aspiration biopsy (IAB) samples taken without a sitopathologist accompanied during the process. We also intended to investigate whether the samples obtained by both techniques have a significant difference between the results according to the Bethesda category. A total of 625 nodes of 572 patients suitable for biopsy were included in this retrospective study. IABs were performed by initiative radiologists without a sitopathologist accompanying during the processes. The samples were prepared using either conventional broadcasting or SBS preparation methods. The cytopathological diagnosis adequacy and cytopathological results of the samples were assessed according to the Bethesda category and the relationship between the morphological findings was assessed as retrospective. 338 of all biopsy samples (54.1%) were prepared using the SBS spread method, 287 (45.9%) were prepared as conventional smar. The malignity rates of biopsy samples were found similar in both SBS and conventional spread methods. Considering the nodes classified as categories II, III, IV, V, VI in Bethesda, there was no statistical difference between the results of both methods. The non-diagnostic biopsy rate was higher in samples prepared by conventional spread method (p<0,001). The result: In this study, the IIB qualification rate in the SBS method was significantly high compared to the conventional smear method. SBS was more practical and faster than the conventional transmission method. We think that the SBS method can be preferred in the IAB of the thyroid nodes. (SETB-2021-11-335)
