细针穿刺细胞学检查历(FNAC）已作为甲状腺结节病人的标准诊断方法应用，因而术中活组织采取冰冻切片检查的必要性成为讨论的课题。作者对5年期间收治的甲状腺结节病例。同时作术前细针穿刺和术中活检的170例连续性病人进行对比研究。此组病人平均年龄41岁（9～78岁）。男性154例，女性16例。FNAC细胞学判断，术中活检均分为良性、恶性和可疑三类，并提出各自的诊断标准。切除标本的组 Fine needle aspiration cytology (FNAC) has been used as the standard diagnostic method for patients with thyroid nodules. Therefore, the necessity of frozen biopsy of intraoperative biopsy has become the subject of discussion. The authors documented cases of thyroid nodules treated during the five-year period. At the same time, 170 consecutive patients undergoing preoperative fine needle aspiration and intraoperative biopsy were compared. The average age of this group of patients was 41 years (9 to 78 years). There were 154 males and 16 females. FNAC cytology judged that intraoperative biopsy was divided into benign, malignant and suspicious categories, and put forward their own diagnostic criteria. Resection specimen group
