Objective/hypothesis: To determine the need for intraoperative frozen section to guide the extent of thyroid surgery in the presence of an adequate preoperative fine-needle aspiration (FNA) finding.Methods: Charts of patients who presented from 1995 to 1998 to the two senior authors were reviewed. A total of 82 patients were found who satisfied the inclusion criteria of having both an adequate FNA and frozen section. The extent of surgery was based on the frozen section finding for all the patients in this study. The authors looked at the number of cases in which the surgical management would be changed if the frozen section was not obtained and the surgical decision was based only on preoperative FNA and intraoperative findings.Results: FNA revealed papillary carcinoma in 18 patients that was confirmed by intraoperative frozen section and final pathology. In the remaining 64 patients, the FNA diagnosis was either benign or suspicious. When routine frozen section was done, 61 of these 64 patients were found to have either benign pathology or pathological diagnosis that was deferred to permanent section. Only three patients were found to have malignancy on frozen section that was missed by FNA. Of these three patients, two had obvious findings of malignancy at the time of surgery. This leaves only one patient with carcinoma that was missed by FNA and intraoperative findings but detected by the intraoperative frozen section.Conclusion: Of the 82 patients in this study, only one extra case of malignancy would be missed by elimination of the routine use of intraoperative frozen section. The authors conclude that the routine use of intraoperative frozen section may be unnecessary. The use of an adequate preoperative FNA together with sound clinical judgment at time of surgery can adequately guide the extent of surgical resection. [ABSTRACT FROM AUTHOR] |
