Parotid / Submandibular
Your parotid and submandibular glands are two of three major salivary glands that make saliva and release it into the mouth. Parotid glands are located in the upper part of each cheek, close to the ear. The duct of each parotid gland empties onto the inside of the cheek, near the molars (back teeth) of the upper jaw. Submandibular glands, in the floor of the mouth, have ducts that empty behind the lower front teeth.
You will not be required to change for this ultrasound examination. You will lie on your back during the study, with the neck turned to either the right or left. A small quantity of clear gel will be applied to your skin in the area being examined, this is to enable the ultrasound to penetrate the skin layer.
Ultrasound is a painless and effective wave to examine both the parotid or submandibular glands, with the sonographer using high frequency sound waves to image the tissue and Doppler ultrasound to assess the blood flow within the gland. During the ultrasound, the size of the gland on the right and left side is measured, the blood flow assessed and any focal area, such as dilated ducts, calcifications (stones), soft tissue masses, and cysts detailed.
