Abstract: To evaluate the influence of thyroid nodule size on the quality of ultrasound-guided fine-needle aspiration biopsy (US-FNAB) specimens. The data of 614 patients with US-FNAB independently completed by the same ultrasound doctor were retrospectively analyzed. According to the diameter of thyroid nodules, they were divided into group A (<5 mm), group B (5-10 mm) and group C (>10 mm), and the unsatisfaction rates among the groups were compared. There were 189 nodules in Group A, and the rate of unsatisfaction was 11.6% (22/189). In group B, there were 397 nodules, and the unsatisfaction rate was 10.8% (43/397). In group C, there were 147 nodules, and the unsatisfaction rate was 9.5% (14/147). There was no significant difference in the rate of unsatisfaction among the three groups (P>0.05). For a doctor with rich operating experience, the size of thyroid nodules does not affect the quality of US-FNAB specimens.
