Why consider interventional radiology (IR)?
In select complex cases—deep stones, tight strictures, or altered anatomy—interventional radiology adds precision. Using ultrasound and fluoroscopy, IR specialists can access the duct, define strictures, and assist stone removal. This partnership expands minimally invasive options and reduces the need for open surgery.
Common IR techniques
- Ultrasound-Guided Duct Cannulation: Helps in difficult anatomy, allowing safe catheter placement.
- Fluoroscopic Sialography: Contrast outlines the duct tree, revealing parotid duct obstruction or submandibular duct calculus.
- Balloon Dilation: Under imaging, strictures are dilated; a stent may be placed.
- Wire-Guided Basket Retrieval: Selected stones can be mobilised or captured.
- Rendezvous Procedures: IR access from outside meets sialendoscopy from the mouth, improving success in challenging cases.
Benefits and safety
Benefits include accurate mapping, improved access in scarred ducts, and higher success for complex parotid sialolith or submandibular sialolith scenarios. Radiation doses are kept as low as reasonably achievable, and ultrasound is used whenever possible. Complications (infection, duct injury) are uncommon with experienced teams.
Recovery and follow-up
Most IR-assisted procedures are day-care. Aftercare mirrors endoscopic protocols: hydration, warm compresses, sialogogues, and massage swollen salivary glands. When stents are placed, they're removed in clinic within days to weeks.
Costs and access in India
Costs depend on imaging time, disposables (balloons/stents), and the need for combined procedures. Our centre in New Delhi coordinates ENT/Head & Neck surgery and IR teams to deliver streamlined, cost-effective care.
If you've had multiple flares despite prior treatments, ask whether an IR–sialendoscopy combined plan is right for you.
