Abstract

<abstract abstract-type="author" id="abs0005"> <title id="sect0005">Abstract</title> <sec> <title id="sect0010">Objective</title> <p id="spar0005">The aim of this study is to compare preoperative fine needle aspiration cytology (FNAC) and intraoperative frozen section (FS) for the correct identification of malignancy, histological grade, and histological type.</p> </sec> <sec> <title id="sect0015">Methods</title> <p id="spar0010">FNAC was performed on all 105 patients and FS on 71 patients with parotid carcinoma.</p> </sec> <sec> <title id="sect0020">Results</title> <p id="spar0015">The rate of correctly determining the histological grade by FNAC and FS was 32% and 73%, respectively. The correct diagnosis rate for both the histological type and grade by FNAC and FS was 20% and 48%, respectively.</p> </sec> <sec> <title id="sect0025">Conclusions</title> <p id="spar0020">The correct grading of both high and low/intermediate grade carcinoma is possible in 70–80% of patients by FS. If the histological grade is identified correctly, the extent of resection can usually be decided appropriately. Therefore, we should put emphasis on determining the histological grade.</p> </sec> </abstract>
