涎腺肿块的细针吸取细胞学诊断研究

目的 通过对细针吸取细胞学(fine needle aspiration cytology,FNAC)与病理诊断的比较,评价本组细针吸取细胞学在涎腺肿块术前诊断的价值.方法 采用"友谊式"细针穿刺器,对81例涎腺肿块进行FNAC检查,将其结果与术后组织病理结果对照,得出FNAC诊断准确率,同时计算微小组织病理学诊断的准确率.结果 本组FNAC定性诊断准确率达92.59%,误诊率7.41%;组织学分类完全符合率达67.90%,基本符合率24.69%,不符合率7.41%;微小组织病理学诊断准确率达85.71%,误诊率14.29%.结论 FNAC对涎腺肿块的定性诊断的准确性较高,对术前诊断有重要的参考意义.由于FNAC诊断不同类型涎腺肿块的完全符合率不同,其临床可参考性也不同.

Diagnostic study of fine-needle aspiration cytology of salivary gland masses

Objective To evaluate the fore-operative diagnose of salivary gland masses by fine-needle aspiration cytology(FNAC).MethodsFine-needle aspiration of salivary gland masses was performed in 81 cases with fine-needle aspirator of "friendship type".The results were compared with corresponding post-operative histopathological diagnosis(HPD),and the accuracy of histopathology of mini-tissue was studied.ResultsThe qualitative diagnostic accuracy of FNAC was 92.59% while the misdiagnostic rate was 7.41%;the accurate rate of defining mass type was 67.90% while misdiagnostic rate was 7.41%;the accurate and error rate of histopathology for diagnosis of mini-tissue was 85.71% and 14.29%,respectively.ConclusionFine-needle aspiration has a high qualitative diagnostic accuracy of salivary gland masses and can serve as an important reference for fore-operative diagnosis.The FNAC's value varies in different type of lesions.
