Sialendoscopy is a modern, gland-sparing way to treat problems inside the salivary glands. Instead of removing a gland that swells or gets blocked, a very fine scope is passed into the duct to find and treat the cause directly. This keeps the gland working and usually leaves no scar. At THANC Hospital in Chennai, Dr. Vidhyadharan Sivakumar uses sialendoscopy to treat salivary stones, narrowed ducts and unexplained swelling. This page sits within our wider sialendoscopy and salivary care.
What Is Sialendoscopy?
Sialendoscopy uses a tiny scope, finer than a strand of spaghetti, to look inside the salivary ducts. The scope enters through the natural duct opening inside the mouth, so there is usually no skin incision. Through it, the surgeon can see the inside of the duct, find a blockage, and treat it in the same sitting.
It can be used in two ways. As a diagnostic tool, it shows exactly what is causing the swelling. As a treatment, it allows stones to be removed and narrowed ducts to be opened.
How It Compares With Older Treatment
Before sialendoscopy, a salivary gland that kept blocking or swelling was often removed through a neck incision. That worked, but it meant losing the gland, a neck scar, and a small risk to the nerves nearby. Removing stones near the surface through the mouth was possible, but deeper stones and narrowed ducts were hard to treat without taking the gland.
Sialendoscopy changed this picture. By working through the natural duct opening with a fine scope, the surgeon can reach problems deep inside the gland that were once out of reach, and treat them without removing the gland. For most patients with stones, narrowing, or repeated swelling, this means a gentler day-case procedure instead of an operation, while keeping the gland and its saliva. Gland removal is now reserved for the few glands that are too badly damaged to save.
What It Treats
Sialendoscopy is used for:
- Salivary stones, which block the duct and cause mealtime swelling. See our salivary stone removal page.
- Narrowed or scarred ducts (strictures), which slow the flow of saliva. See our salivary duct stricture page.
- Repeated swelling or infection of a gland with no obvious cause.
When It Is Recommended
Sialendoscopy is a good option when a gland swells, blocks or gets infected, but the gland itself is otherwise healthy and worth keeping. It is the first choice before considering removal of the gland, which is reserved for badly damaged glands. Keeping the gland matters, because each salivary gland contributes to a comfortable, moist mouth.
Why Keep the Gland?
In the past, a gland that kept swelling or getting blocked was often removed through a neck incision. Sialendoscopy changed this. By treating the blockage from the inside, it lets the surgeon solve the problem while leaving the gland in place. This avoids a neck scar, protects the nerves that run close to the gland, and keeps the gland's contribution to your saliva. For most patients with stones or a narrowed duct, this gland-sparing approach is both gentler and more effective.
How It Is Done
The procedure is done under general or local anaesthetic, depending on what is planned. Dr. Vidhyadharan gently opens the natural duct opening inside the mouth and passes the fine scope into the duct. Viewing the inside of the duct directly, he can see exactly what is causing the blockage and treat it in the same sitting.
Depending on what is found, he can:
- Remove a stone, often by catching it in a tiny basket and drawing it out. See our salivary stone removal page.
- Open a narrowed segment of the duct by gently stretching it with a small balloon or dilator. See our salivary duct stricture page.
- Wash out the duct and treat inflammation, sometimes with medication delivered through the scope.
A tiny tube, called a stent, may be left in the duct for a short time to keep it open while it heals. In most cases there is no skin incision at all.
What to Expect
Before the procedure. Examination and an ultrasound scan to plan the approach. A diagnostic sialendoscopy is sometimes done first to see inside the duct. Dr. Vidhyadharan explains what is likely to be found and treated.
The procedure. A short, minimally invasive procedure, usually a day case, taking under an hour in most cases.
Recovery. Most patients go home the same day. Mild swelling of the gland can occur for a short while and settles quickly.
Recovery and Aftercare
Recovery is quick, and a few simple habits help the gland settle and keep working well:
- Stay well hydrated to keep saliva flowing and the duct clear.
- Massage the gland gently, if advised, to help move saliva through.
- Use sour sweets or citrus if suggested, since these encourage saliva flow.
- Keep good oral hygiene to support healing and reduce infection.
- Report any return of swelling so it can be treated early before it builds up.
Outcomes
Sialendoscopy clears most blockages while keeping the gland and avoiding a neck operation. Patients keep normal saliva and return to daily life quickly. Because the gland is preserved, the long-term result is usually very good. Some problems, such as a stricture, can return and may need a repeat treatment, but the gland-sparing approach can simply be used again.
Why Choose Dr. Vidhyadharan at THANC Hospital
- Head and neck surgical training. MCh (Head & Neck Surgery) and European Board certification (FEB-ORL HNS), with expertise in gland-sparing salivary surgery.
- Minimally invasive technique that keeps the gland and avoids a scar.
- 3000+ head and neck operations, the volume linked to better outcomes.
- In-house imaging at THANC Hospital for accurate planning.
Treatment Cost and Insurance
The cost depends on what is treated, whether it is a day case or needs admission, and the room category. Most major health insurers in India cover medically indicated salivary procedures, including cashless treatment at empanelled hospitals. Eligible patients may also use government schemes such as Ayushman Bharat (AB-PMJAY) or the Tamil Nadu CMCHIS.
