Stenoses of the salivary ducts-sialendoscopy based diagnosis and treatment

Published:August 31, 2012DOI:


      Our aim was to analyse the nature of a sialendoscopy-based classification and present its use in the treatment of stenoses of Wharton's and Stensen's ducts. The classification of stenoses of Wharton's duct has not been published before. We did 133 sialendoscopies in 114 patients who presented with possible obstruction of the ducts to the tertiary centre for ENT at the University Department in Poznań. Twenty-seven patients had their parotid ducts treated, and 24 their submandibular ducts. Suspicion of stenotic changes of the ductal system was suggested during ultrasound examination. They were examined with semirigid endoscopes that enabled direct visualisation of the stenotic areas. A total of 69 stenoses were diagnosed in 51 patients. Stenoses were divided into three groups according to their site. Patients with stenosis of the salivary ducts were treated by dilatation of the stenotic area, intraductal steroid injections, and insertion of a stent for 14–21 days. Forty of the 51 reported considerable improvement, and 7 partial improvement. Four patients had no improvement.
      Sialendoscopy is a safe way to treat obstruction of the salivary glands. Short and medium term follow up show that it is extremely successful.
