You have hundreds of salivary glands in and around your mouth that create saliva, which helps to keep your mouth moist and aids in swallowing, speaking and eating. The aim of the study is to define the utility of ultrasound (US) in differentiating benign from malignant parotid tumors as well as pleomorphic adenomas (PA) from monomorphic adenoma (MA). Most parotid tumors are benign with malignancy only comprising approximately 15% to 32%. There are many other salivary glands in the lips, cheeks, mouth and throat. A fibrous capsule surrounds the gland, formed by the superficial (investing) layer of the deep cervical fascia, creating the parotid space. Zengel P, Notter F, Clevert DA.
