AIMS: This study was conducted to see whether thehilar echogenicity aloneis a good criteria for detection ofcervicallymph node metastasis in patients with oral squamous cell carcinoma(OSCC). MATERIALS AND METHODS: Twenty patientswithOSCC ( 14 males and 6 females) , theirage 40- 90years, were examined sonographically,and the number of cervical lymph nodes studied was 112. Hilar echogenicity alone was used as a criteria to differentiate between benign and malignant cervical lymph nodes. Lymph nodes were evaluated for their echogenic hilus,number, size, site, shape, as well as for necrosis. The results ofUS evaluation were compared with histopathologic outcomeusingunpaired t-test and Fisher’s exactprobabilitytest.RESULTS:Ultrasound examination yielded a sensitivity as84.09%, specificity 95.59%, accuracy 91.07%, positive predictive value (PPV) 92.5%, and negative predictive value (NPV) 90.28%. CONCLUSIONS. Sonographic examination have a high accuracy in detecting cervical lymph node metastasis in patients with oral squamous cell carcinoma,depending on hilar echogenicity as a diagnostic criteria .
