Abstract

Background.

This study evaluates the role of frozen section (FS) in surgical decisions for nodular thyroid disease when a preoperative fine‐needle aspiration cytology (FNAC) is available.

Material and Method.

The charts of 113 patients who underwent thyroidectomy for nodular goiter were reviewed. Each patient underwent FNAC, FS, or both. Results were compared with the final pathologic examination to evaluate their effectiveness in predicting malignancy.

Results.

The sensitivity and specificity of FNAC alone (49 patients) were 73% and 93.5%, respectively, and of FS (111 patients) 68% and 99%, respectively. The result of fine‐needle aspiration cytology was: benign (n = 8), malignant (n = 13), indeterminate (n = 25), and nondiagnostic (n = 3). All cases diagnosed as benign on FNAC were benign on final pathology, but of the six FS performed in these cases, four were benign and two were suspect. Of the 13 FNAC that were interpreted as malignant, 11 and 10 proved to be malignant on final pathology and FS, respectively. The 25 indeterminate cases on FNAC were on final pathology benign (n = 21) and malignant (n = 4) and on frozen section were benign (n = 12), malignant (n = 2), and suspect (n = 11).

Conclusion.

When results of FNAC are interpreted as benign or malignant, FS is of little value, because it does not change the extension of thyroidectomy. FS proved useful in determining the extent of thyroidectomy only when results of the FNAC were suspect or atypical. © 2002 Wiley Periodicals, Inc. Head Neck 24: 000–000, 2002
