Sialodochoplasty in the treatment of salivary-duct stricture in chronic sialoadenitis: technique and results.
OBJECTIVE
This study was undertaken to investigate peroral balloon angioplasty of salivary-duct strictures (sialodochoplasty) in chronic sialadenitis, analysing the technique, results and limitations.


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.
