Swelling during meals: Often suggests obstruction from a sialolith or duct stenosis
Persistent pain or tenderness: Can reflect infection (sialadenitis) or deep obstruction
Dry mouth (xerostomia): Medication side effects, dehydration, or autoimmune disease
Recurrent cheek or jaw swelling: Think parotid duct obstruction or submandibular blockage
Lump or mass: Requires careful assessment to rule out tumours
Step 1 - History and examination
We document symptom timing, triggers, hydration, medications (anticholinergics, antihistamines), prior infections, dental issues, and autoimmune features (dry eyes, joint pain). Examination includes gland palpation, duct orifice inspection under the tongue/cheek, and glandular massage to assess saliva quality and flow.
Step 2 - First-line imaging: ultrasound
Ultrasound is quick, radiation-free, and excellent for detecting stones and ductal dilation. It also helps identify cysts (ranula), abscesses, or masses requiring further work-up. In experienced hands, ultrasound guides care on the first visit.
Step 3 - Cross-sectional imaging when needed
CT scan: Best for calcified stones (tiny saliva crystals/parotid calcifications), mapping complex stones, and surgical planning (parotid duct stone CT when indicated).
MRI / MR sialography: Superior for soft tissue, inflammation, autoimmune disease, and characterising masses.
Step 4 - Diagnostic sialendoscopy
If obstruction is suspected, sialendoscopy gives a definitive look inside the duct. We can remove stones, dilate stenosis, and irrigate debris in the same sitting. This avoids delays and often resolves the problem without open surgery.
Step 5 - Laboratory tests (when indicated)
Autoimmune panel (e.g., for suspected Sjögren's), inflammatory markers, cultures if pus is expressed, and baseline bloods for surgical planning.
Differential diagnosis: not every swelling is a stone
We provide a clear plan and transparent estimate. Sialendoscopy cost in India varies with complexity; ultrasound is often performed in-house to speed diagnosis.
If you have persistent symptoms of a blocked salivary duct, book a comprehensive evaluation. Early, accurate diagnosis prevents complications and preserves gland function.
Frequently asked questions
What tests diagnose salivary gland stones?
High-resolution neck ultrasound is first-line. MRI sialography or CT sialography maps duct anatomy. Diagnostic sialendoscopy confirms stones, strictures, or mucus plugs directly and allows same-session treatment.
When is imaging needed before sialendoscopy?
Imaging helps locate stone size and position, assess gland viability, and plan scope selection. It is especially valuable for recurrent sialadenitis, deep intraglandular stones, or prior failed procedures.
