In Europe, ultrasound (US) is the preferred imaging method for observing parotid lesions. Although high-resolution conventional ultrasound can clearly show focal lesions in the parotid gland, it is less effective in identifying the tumor mass and broader lesions in the parotid gland. Ultrasound elastography is an emerging technology that can quantitatively assess changes in parotid tissue stiffness. In recent years, the application of parotid tissue has increased, and the pulse generated by it stimulates the local displacement of the tissue in the selected region of interest (ROI) and quantifies it. The indicator indicates its mechanical properties. Recent studies have shown that this technique can assess changes in tissue elasticity in different diseases of the parotid gland. This review article highlights the value of ultrasound elastography in diffuse and focal lesions of the parotid gland.
