Abstract
In order to evaluate the advantage of the cytological diagnosis of tumors in the head and neck, the author examined one hundred and eight composed of fifty-eight benign lesions and fifty malignant lesions. Cytological diagnosis was found to correlate with histopathological diagnosis in 85.2% of the cases examined. The accuracy rate was 78% in malignant cases and 91.4% in benign cases. In aspiration smear, the accuracy rate was 91.7% and 90% in direct imprint of the surface of the lesions. It was confirmed that the cytological diagnostic method is clinically significant and useful for the diagnosis of tumors in the head and neck.
