Fine needle aspiration cytology of thyroid nodules: Review of 36 months experience

Studies suggest that fine needle aspiration of thyroid nodules is a sensitive and specific tool for the detection of thyroid cancers thus preventing unnecessary operations. This technique was introduced in our institution in 1987 and performed where indicated under strictly defined criteria. We reviewed the aspirates performed over a 36 month period to critically evaluate the role of this procedure. Review was limited to F.N.A.S of nodules considered to be potentially malignant by conventional criteria and hence all the following criteria needed to be fulfilled: (1) solitary or dominant nodules in a multinodular goitre, (2) cold on isotope scanning, (3) solid or complex cystic nodule on ultrasonography.
