目的：　探讨细针吸取细胞学 (FNAC)检查对儿童甲状腺炎的诊断价值。方法：　采用FNAC检查法诊断儿童甲状腺。结果：　经细胞学诊断为甲状腺炎共计 10 0例,经临床治疗及其它实验室检查结果相符的98例(98%),只有2例(2%)在分类上出现误差,而血清学(T3 ,T4 ,TG ,TM ,TSH)检查敏感性则相对较低,桥本氏甲状腺炎为63.1%～73.6%,淋巴细胞性甲状腺炎为26.0%～84.7%,其它血清学检查均无意义。结论：　FNAC检查法吸出细胞成分充足,几乎不含血液成分,有利于甲状腺炎的诊断及分类。

OBJECTIVE: To study the value of the fine needle aspirationin cytological examination for child thyroiditis. METHODS: The fine needle aspiration was performed in cytological examination for 100 patients with child thyroiditis. RESULTS: In 98 patients (98%) the clinical treatment coincided with other laboratory examinations. Two patients (2%) were misdiagnosed by typing. The sensitivity of serology (T 3, T 4, TG, TM, TSH) examination was lower. The hashimoto's thyroiditis diagnostic rate was 63.1% ～ 73.6% , lymphocytic thyroiditis was 26.0% ～ 84.7% , and other serological examinations showed no significance. CONCLUSIONS: The fine needle aspiration can obtain enough tissues for diagnosis.
