OBJECTIVES: To study the accuracy of intraoperative frozen section diagnosis in assessing margins in oral cancer resection and to evaluate the role of frozen section diagnosis as a guide in resection of oral cancer lesions. PATIENTS AND METHODS: The fresh tissue samples from the margins of lesions of patient with preoperative diagnosis of oral squamous cell carcinoma were used. The frozen sections are prepared immediately and examined by oral pathologist for the study. The results of these sections were compared with the results of histologic findings obtained by routine paraffin embedded Haemotoxylin and eosin method. RESULTS: The total of 184 margins, from 47 patients were examined. 178 margins showed concordance with the permanent section of the same tissue sample (seven false negative and one false positive), an accuracy rate of 96.74%. CONCLUSION: Frozen section is a helpful tool in intraoperative decision making in indicated situation. The results are highly specific but only moderately sensitive. The surgeon and the pathologist must understand the limitations of frozen sections.
