[Abstract]Objective：Toinvestigatetheefectofthyroidnodulessizeonthesatisfactionof specimens inultrasound-guided fine-needeaspiration（US-FNA）biopsy.Methods：Atotalof293patientswith293thyroidnoduleswhounderwent US-FNA biopsywereretrospectivelycollected.Accordingtothemaximumdiametershowedongrayscaleultrasound，allnoduleswere divided intogroupA（35nodules，lessthan5mm），groupB（118nodules，5-10mm），andgroupC（140nodules，morehan 10mm）.AccordingtothepathologicalBethesdasystem，thesatisfactionoftheneedlebiopsyspecimenwasdefinedascategory I（unsatisfactory specimens），and category I-M （satisfactory specimens）. The differences in specimen satisfaction among thethreegroupswerecompared，andthefactorsafectingthesatisfactionofthyroidnodulespecimenswereanalyzed.Results： The specimens satisfaction in groups A，B，andC were91.4%（32/35），92.4%（109/118），and 92.9%（130/140），respectively. There was no statistically significant diffrence among the three groups （ P >0.05），and pairwise comparisons among the three groups showed no statistically significant differences either （all P>0.05 ）.Conclusions：The size of thyroid nodules has no significanteffectonthespecimenssatisfactionofUS-FNAbiopsy.SatisfactoryspecimenscanstillbeobtainedbyUS-FNA biopsy of small thyroid nodules（the maximum diameter less than 5mm ）with clinical diagnosisand treatment needs，which were previously considered to have a low success rate of puncture.
