Olsen and colleagues investigated the accuracy of frozen section pathologic analysis of parotid lesions by comparing it with the final pathologic diagnosis to help determine the value of this intraoperative tool in surgical decision making. The main outcome was a change in diagnosis in parotidectomy reports from 2000 through 2009 for 1339 specimens representing 693 benign and 268 parotid primary and metastatic lesions. Only a few of the diagnosis adjustments would have affected intraoperative decision making, so the authors concluded that frozen section pathologic analysis was highly accurate and useful intraoperatively.
