Sialodochoplasty in the treatment of salivary-duct stricture in chronic sialoadenitis: technique and results

PURPOSE: This study was undertaken to investigate peroral balloon angioplasty of salivary-duct strictures (sialodochoplasty) in chronic sialadenitis, analysing the technique, results and limitations. MATERIALS AND METHODS: Nine patients underwent sialodochoplasty: seven for Stensen''s-duct strictures and two for Wharton''s-duct strictures. One patient had a double stricture of Stensen''s duct and another a salivary stone associated with a Wharton''s-duct stricture. All patients were subjected to preliminary sialography to evaluate stricture site, length and grade. Sialodochoplasty was performed after local anaesthesia and progressive dilation of the salivary-duct orifice. RESULTS: The stric…
