RESUMEN
Back ground: Fine needle cytology is a valuable adjunct to preoperative diagnosis of thyroid lesions and it can helps in assessment of benign and malignant condition.Aims and objectives: To compare the efficacy of fine needle non aspiration cytology (FNNAC) with that of fine needle aspiration cytology (FNAC) in thyroid lesions.Materials and methods:FNAC and FNNAC techniques were studied in 50 cases of thyroid lesions. All the needle-sampling procedures were done by a single operator.The samples were assessed cytologically and evaluated using Mair et al scoring systemResult: The degree of cellular trauma, degree of cellular degeneration, blood contamination were less and the retention of architecture and cellular yield was more in FNNAC compared to FNAC with significant statistical difference. More number of FNNAC smears are diagnostically superior. Conclusion: The FNNAC technique is the first and best choice for vascular organ like thyroid compared to FNAC.
