abstract
- Over 500 fine (no. 22) needle aspiration biopsies were done on head and neck lesions. The total accuracy for the series was 94.5 percent. The accuracy rates for thyroid, salivary and metastatic or benign lymph node lesions were similar: approximately 95 percent. Only lymphomatous lesions gave a lower accuracy rate: 75 percent. This method of evaluating masses in the head and neck is simple, rapid, inexpensive, well-tolerated and harmless, and is very accurate when there is close cooperation between the clinician and the cytopathologist.
