Sialendoscopy

What is Sialendoscopy?

Sialendoscopy is an advanced, minimally invasive technique used to diagnose and treat salivary gland disorders. Using a miniature endoscopes, specialists can navigate the salivary ducts, identify blockages, and perform targeted treatments preserving the natural gland. This procedure more often than nought, usually eliminates the need for traditional gland removal surgery, significantly reducing the risk of complications and preserving normal saliva flow.

Why Sialendoscopy Is a Better Choice Than Traditional Salivary Gland Surgery?

Sialendoscopy is a modern, minimally invasive procedure used to treat salivary gland problems such as stones, recurrent swelling, and infections. Unlike traditional salivary gland surgery, which often requires external cuts and sometimes removal of the entire gland, sialendoscopy treats the problem from inside the salivary duct using a tiny camera. This means there are no visible scars, less pain, and a much faster recovery.

One of the biggest advantages of sialendoscopy is that it preserves the salivary gland. Instead of removing the gland, doctors can remove stones, widen narrow ducts, and wash out inflammation while keeping the gland healthy and functioning. Studies show that more than 90% of salivary glands can be saved, and most patients experience significant relief from symptoms such as pain and swelling.

Because sialendoscopy avoids open surgery, the risk of nerve injury, facial weakness, and long hospital stays is much lower. The procedure is usually done as a day-care surgery, allowing patients to return to normal activities quickly. It is also safe for children and patients with recurrent salivary gland problems.

Overall, sialendoscopy offers a safer, effective, and gland-saving alternative to traditional salivary gland surgery.

Understanding the Salivary Glands

The human body contains three main pairs of salivary glands in the head and neck region, each contributing to saliva production for digestion, oral moisture, and tissue protection:

Sublingual glands: Positioned beneath the tongue, these produce a thinner, watery saliva.
Submandibular glands: Located under the jawbone, they secrete thicker saliva that is more susceptible to certain complications.
Parotid glands: Situated in front of the ears, these are the largest glands and generate a slightly mucous-like saliva.

Saliva travels from these glands into the mouth through narrow ducts. When blockages occur, normal flow is disrupted, leading to discomfort and potential complications.

Common Causes of Salivary Duct Blockage

Stone in the submandibular duct: Also termed Wharton's duct calculus.
Ductal stenosis or stricture: Often resulting from prior inflammation or injury.
Mucus plugs: These can obstruct the pathway.
Scarring: Secondary to recurrent infections or trauma.

Contributing factors may include dehydration, certain medications, or autoimmune conditions such as Sjögren’s syndrome, though stones remain the primary culprit.

Understanding and Managing Salivary Stones (Sialolithiasis)

Salivary stones, or sialoliths, are small mineral deposits that can block the flow of saliva from your glands into the mouth. This usually affects the submandibular gland (under the jaw) or the parotid gland (in front of the ear).

One of the most common clues is pain and swelling around mealtimes. This happens because your glands try to release more saliva when you eat, but the blockage prevents it from flowing normally. Pressure builds up, causing discomfort that often comes and goes.

You might notice:

Swelling and pain under the jaw or near the ear, depending on which gland is affected.
Tenderness that worsens before eating and eases a little afterward.
Dry mouth or less saliva, making chewing and swallowing harder.
Recurrent swelling or infections in the same area.
Occasionally, a bad taste or pus discharge inside the mouth if an infection sets in.

If these symptoms sound familiar, it's important to get them checked early. Delaying treatment can lead to ongoing inflammation, repeated infections, or long-term damage to the gland.

When to See a Specialist

If you’re experiencing pain, swelling, or repeated infections around your jaw or mouth, it’s best to see an ENT specialist experienced in sialendoscopy. Early evaluation can make all the difference.

Timely treatment can:

Relieve pain and swelling,
Prevent future infections, and
Protect your natural salivary function for the long term.

How Sialendoscopy Transforms Treatment

Sialendoscopy is a minimally invasive procedure that employs a micro-endoscope—thinner than a pencil—to visualize and treat the salivary ducts directly through their natural oral opening. This approach enables the specialist to:

Accurately locate stones, strictures, or mucus plugs.
Remove stones using miniature baskets, graspers, or laser fragmentation.
Dilate narrowed ducts to restore patency.
Irrigate debris and address underlying inflammation.

Unlike traditional open surgery, which historically involved submandibular gland excision (sialadenectomy), sialendoscopy preserves glandular tissue and function. For parotid gland stones, it significantly reduces the risk of facial nerve injury, preserving facial movement and expression.

Key Benefits of Sialendoscopy

This technique offers numerous advantages tailored to patient comfort and outcomes:

Scar-free: Performed entirely intraorally, with no external incisions.
Outpatient procedure: Most patients are discharged the same day.
Minimal discomfort: Conducted under local anesthesia or brief general anesthesia.
Rapid recovery: Return to normal activities typically within 1–2 days.
Lower complication rates compared to open surgery.
Repeatable: Suitable for recurrent stones, which occur in approximately 5–10% of cases.

Overall, sialendoscopy provides effective, gland-sparing relief for sialolithiasis.

Sialendoscopy Cost Considerations

The cost of sialendoscopy varies depending on the gland affected (parotid versus submandibular), stone size and quantity, need for adjunct procedures (e.g., duct dilation), and facility type. In many cases, it proves more economical than traditional gland removal due to shorter hospital stays, faster recovery, and fewer complications. Patients are encouraged to consult their insurance provider for coverage details.
