Patients who have had more than basic dilation of the papilla may benefit from short-term intubation to allow for drainage of the saliva duct. The stent can be placed into the salivary duct via the papilla after an incision or a papilotomy of the Wharton's or Stenson's duct. The stent can be placed via a sialodochotomy.
The Walvekar Salivary Duct Irrigating Stent™ has the additonal feature of a Luer-lock attachment on either end to facilitate the infusion of medication or the irrigation of saline after stent is inserted.
