Abstract		We tested the reliability of ultrasound combined with ultrasound guided aspiration biopsy (USGAB) and the usefulness of lymph node size parameters for the detection of subclinical neck metastases. In 77 patients with squamous cell carcinomas of the head and neck, 121 neck sides with no palpable regional metastases were examined by ultrasound. Depending of the results obtained, ultrasound-guided aspiration biopsy was performed on 64 neck sides. Following surgery, the overal results of ultrasound - ultrasoundguided aspiration biopsy were compared with the histological findings of the dissected lymph nodes. The study showed a 77 % sensitivity, 100 % specificity and 95 % accuracy of ultrasound and ultrasound-guided aspiration biopsy. The negative predictive value was 94 %, and the, positive 100 %; the most reliable lymph node size parameter was the ratio of transversal to longitudinal diameter. The results of this study showed that ultrasoundguided aspiration biopsy is an appropriate method for the detection of subclinical regional neck metastases.
