Abstract

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 stricture was successfully dilated in 7/9 patients. The stricture was unchanged after dilatation in one patient, and in another, it recurred after 13 months. In the patient with a double stricture of Stensen''s duct, one was resolved and the other was only partially dilated, with significant symptom improvement. One patient developed a new episode of sialadenitis after 3 months, which resolved with medical therapy. Five out of seven patients were asymptomatic at follow-up.CONCLUSIONS: Sialodochoplasty is an effective procedure in the treatment of salivary-duct strictures, improving symptoms in the majority of patients. The procedure is repeatable and can be proposed as a first-line treatment for symptomatic salivary-duct stricture.
