Ultrasound Parotid Gland, in Visit Clinic

Parotid ultrasound evaluates gland size, shape and internal architecture, detecting focal lesions such as cysts, stones, abscesses and solid masses (benign or malignant). It identifies inflammation or chronic sialadenitis, ductal dilation, calcifications and enlarged regional lymph nodes. Doppler assesses vascularity. Ultrasound guides needle biopsy or drainage and helps distinguish cystic from solid lesions, though deep-lobe or small lesions may need CT/MRI.

Ultrasound is the first-line imaging for parotid gland lumps—quick, noninvasive, and good for superficial lesions. For deep-lobe masses, complex anatomy, or suspected malignancy, MRI is preferred for superior soft-tissue characterization. Contrast CT helps assess bone involvement, calcifications, or when MRI is contraindicated. Ultrasound‑guided fine‑needle aspiration provides cytology to guide management.

Yes—ultrasound is a first-line test and can usually detect salivary gland enlargement, duct dilation, and many stones (especially in the submandibular gland). Small, deeply located or intraductal stones can be missed, so a normal ultrasound doesn’t entirely rule out obstruction. If suspicion persists, CT, MRI/sialography or ENT referral may be recommended for further evaluation.

Use a high-frequency linear transducer (7–15 MHz). Position the patient supine with neck slightly extended and head turned away. Scan longitudinal and transverse planes from the preauricular area over the parotid to the angle of the mandible and inferior border, imaging superficial and deep lobes. Apply graded compression, use color Doppler for vascularity, measure lesions and nodes, compare the opposite side, and save images.

Seek medical attention for parotid problems if you have sudden, severe swelling with pain, fever, redness or foul discharge from Stensen’s duct; recurrent painful swelling (especially during meals); difficulty opening the mouth, swallowing or breathing; new facial weakness or numbness; or a painless lump that persists or grows for over two weeks. Urgent care is needed for rapid progression or systemic symptoms.

If you have a firm lump near the jaw in front of the ear that persists or grows, you may have a parotid gland tumor. Most are painless and benign, but warning signs include rapid growth, pain, skin changes, numbness or facial weakness. Diagnosis requires clinical exam and imaging (ultrasound/CT/MRI) plus needle biopsy. See an ENT promptly for evaluation.
