“…By considering ultrasonographic features given by Shimizu et al, 6 in this study most of the inflammatory swellings had relatively clear boundaries, irregular shapes, hypoechoic echo intensity and homogeneous ultrasound architecture of lesion. The posterior echoes appeared enhanced and ultrasound characteristics of tissues were cystic or solid in nature ( Table 2, Figures 1 and 2).…”

Objective: The aim of this study was to evaluate the efficacy of ultrasonography in the diagnosis of swellings in the head and neck regions. Methods: For this study, 70 cases with clinically obvious swellings in head and neck regions were selected randomly. The ultrasonographic features considered were shape, boundary, echo intensity, ultrasound architecture of lesion, posterior echoes and ultrasound characteristic of tissues. Intergroup comparisons were made between four different types of swellings: inflammatory; cystic; benign; and malignant. Results: A comparison was made between benign and malignant neoplasms, and the criteria of boundary, echo intensity and ultrasound architecture of lesions are statistically significant as the P-value is ,0.05. The comparison of inflammatory swellings and malignant neoplasms shows that criteria of boundary and ultrasound architecture of lesions are statistically significant. The comparison of cystic swellings and benign neoplasms concluded that only the criterion of ultrasound characteristics of tissues is statistically significant. The comparison of inflammatory swellings and benign neoplasms shows that the criteria of boundary and echo intensity are statistically significant. The comparison of inflammatory swellings and cystic swellings concluded that the criteria of boundary, shape, echo intensity, posterior echoes and ultrasound characteristics of tissues are statistically significant. The comparison of cystic swellings and malignant neoplasms concluded that the criteria of ultrasonography, boundary, shape, echo intensity, ultrasound architecture of lesion, posterior echoes and ultrasound characteristics of tissues are statistically significant as the P-value is ,0.05. Conclusion: It can be concluded that clinical diagnosis had a sensitivity and accuracy of 85.7% and ultrasonographic diagnosis had a sensitivity and accuracy of 98.5%.

“…The sensitivity, specificity and accuracy of the tumour border for determining malignant tumours was 87.5%, 82.1% and 84%, respectively. Mazaher et al 16 reported a sensitivity of 77.8% and Shimizu et al 19 declared a sensitivity of 71.2%. Regarding the homogeneity of the SG mass, 50% of the malignant and 42.8% of the benign tumours were inhomogeneous.…”
