[Fine-needle aspiration biopsy in the diagnostics of nodular thyroid lesions].

The use of the improved puncture needle was evaluated on the basis of 126 biopsies of thyroid nodular lesions. Benign lesions were diagnosed in 114 (90,5%) patients, malignant tumors - in 10 (7,9%) cases. The method proved to be highly effective and provided correct preoperative diagnosis in 96,8% of patients with nodular goiter. Sensitivity of thin-needle aspiration thyroid biopsy was 100%, specificity - 99,95%.
