Purpose:
This paper describes the technique for balloon dilatation of salivary duct strictures and evaluates the clinical and radiographic findings in a consecutive series of 36 affected glands.
Methods:
Thirty-four patients (36 glands) had balloon dilatation of their salivary duct strictures performed under fluoroscopic control. They were evaluated immediately afterwards and at review by sialography.
Results:
In 36 cases attempted, 33 (92%) strictures were dilated. The immediate post-treatment sialogram was available in 28 cases, of which 23 (82%) demonstrated complete and four (14%) partial elimination of stricture. In one case the appearance was unchanged (4%). Review data (mean 6.8 months) were available on 25 glands: 12 were asymptomatic (48%), 12 (48%) had reduced symptoms and one (4%) failed to improve. Sialographic data were available on 21 glands: in 10 (48%) the duct remained patent, in one (5%) the stricture was partially eliminated, in seven (33%) the strictures had returned and in the remaining three (14%) cases there was complete obstruction.
Conclusions:
Balloon dilatation is an effective treatment of salivary duct stenosis. In half the cases the stricture recurred but symptomatic improvement was achieved and maintained in the majority of cases.
