Parotid sialolithiasis—stones in the parotid gland or Stensen's duct—is less common than submandibular stones but causes significant cheek swelling and pain during meals. Parotid sialendoscopy offers a minimally invasive alternative to parotidectomy for suitable ductal stones.

Why parotid stones need careful assessment

The parotid gland sits in front of the ear and drains saliva through Stensen's duct, which opens inside the cheek near the upper molars. Because the facial nerve branches pass through the parotid gland, open surgery around this area needs careful planning. For many ductal stones, sialendoscopy allows the surgeon to work inside the duct rather than through a facial incision.

Parotid gland stone symptoms

  • Swelling in the cheek in front of the ear, often meal-triggered
  • Pain or tightness along the parotid duct toward the upper molar area
  • Visible stone or debris at Stensen's duct papilla on the buccal mucosa
  • Recurrent parotid sialadenitis with pus or foul-tasting discharge

Diagnosis before treatment

Ultrasound is commonly used first to look for stones, duct dilation, abscess, or chronic gland changes. If the stone is small, non-calcified, or deep within the duct, MRI sialography or CT may be useful. Diagnostic sialendoscopy gives direct visual confirmation and may allow the same-session removal of ductal stones, mucus plugs, or debris.

How parotid sialendoscopy works

A specialised sialendoscope is introduced through Stensen's duct opening. The endoscope visualises the duct lumen, identifies parotid duct calculus, and allows stone extraction with micro-instruments or laser fragmentation. Because the facial nerve runs within the parotid gland, duct-first endoscopic approaches avoid nerve risk associated with open parotid surgery.

Treatment options for stones in the parotid gland

Small mobile stones may be removed with micro-baskets or forceps. Larger or impacted stones may need laser lithotripsy to break the calculus into smaller fragments before removal. If inflammation or narrowing is present, the duct can also be irrigated or gently dilated. Antibiotics may be required first if there is acute infection, but antibiotics alone do not remove a persistent blockage.

When parotid gland removal is considered

Parotidectomy is not first-line for stones. It may be needed when stones are deeply intraglandular, endoscopic access is impossible due to severe duct scarring, or malignancy must be excluded. Most parotid duct stones seen at experienced centres are treatable with sialendoscopy.

At the Sialendoscopy Centre at Sir Ganga Ram Hospital, Dr Varun Rai manages parotid and submandibular stones with the same gland-preserving philosophy that has guided over 2,000 procedures. If your swelling is under the jaw rather than near the ear, read the guide to submandibular gland stone treatment. Schedule an evaluation if you have recurrent cheek swelling or suspected parotid sialolithiasis.

Frequently asked questions

What are symptoms of a parotid gland stone?

Cheek swelling in front of the ear during meals, pain near the parotid duct, dry mouth on one side, and sometimes visible stone at Stensen's duct papilla near the upper molar buccal mucosa.

Is parotid sialendoscopy different from submandibular?

The principles are the same, but parotid ducts are shorter and access may require specialised scopes. Parotid sialendoscopy demands careful technique due to proximity to facial nerve branches within the gland.

When is parotid gland removal needed for stones?

Parotidectomy is considered only when endoscopic removal fails repeatedly, stones are deeply intraglandular, or malignancy must be excluded—not as first-line treatment for uncomplicated parotid sialolithiasis.

Can stones in the parotid gland cause cheek swelling?

Yes. A parotid or Stensen's duct stone can block saliva flow and cause cheek swelling near the ear, typically worsening around meals and easing gradually afterward.
