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 planocellular carcinomas of the head and neck, 121 neck sides with no palpable regional metastases were examined using US. Depending on the results, ultrasound-guided aspiration biopsy was performed on 64 neck sides. Following surgery, the results of ultrasound - ultrasound-guided aspiration biopsy were compared with the histological findings of the dissected lymph nodes. The study showed a 77% overall 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 ultrasound-guided aspiration biopsy is an appropriate method for the detection of subclinical regional neck metastases.
Summary		Ocenjevali smo skupno zanesljivost ultrazvoka in ultrazvočno vodene aspiracijske biopsije ter uporabnost parametrov velikosti bezgavk pri ugotavljanju prikritih zasevkov na vratu. Pri 77 bolnikih s ploščatoceličnimi karcinomi glave in vratu smo ultrazvočno pregledali 121 strani vratu brez tipnih področnih zasevkov. Glede na rezultate smo na 64 straneh vratu opravili še ultrazvočno vodeno aspiracijsko biopsijo. Po primerjavi s histološkim pregledom pri disekciji odstranjenih bezgavk je skupna občutljivost ultrazvočne preiskave z ultrazvočno vodeno aspiracijsko biopsijo v raziskavi bila 77%, specifičnost 100% in natančnost 95%. Negativna napovedna veljavnost je bila 94%, pozitivna 100%, najzanesljivejši parameter velikosti bezgavk pa razmerje med prečnim in vzdolžnim premerom. Menimo, da je ultrazvočno vodena aspiracijska biopsija primerna za diagnostiko prikritih področnih zasevkov na vratu.
