Objectives:
The objective of the present study was to test the hypothesis that acute submaxillitis involves salivary duct obstruction. Obstacle characteristics and treatment were analyzed.
Material And Methods:
Patients presenting with an episode of acute submaxillitis between 2009 and 2015 were retrospectively included. All underwent salivary duct imaging and/or sialendoscopy, with pathologic examination if the salivary gland was removed for etiologic diagnosis. For etiological treatment, if the causal lesion could not be treated by isolated sialendoscopy, surgery used a direct approach assisted by sialendoscope. In case of failure of these procedures, submaxillectomy was indicated.
Results:
Twenty-nine patients were included, 28 of whom showed salivary duct abnormality. At least 1 calculus was found in 27 patients; calculi were usually single (n=20), situated in the mid-third (n=21), and large (mean 7.7mm). Ten patients showed stenosis, associated with salivary calculus in 9 cases. Twenty-five patients with salivary duct obstruction underwent sialendoscopy. Isolated sialendoscopy was used in 5 cases, and a combined approach in 13 cases.
Conclusion:
An episode of submaxillitis requires salivary duct exploration by sialendoscopy, to enable early treatment given the prevalence of associated calculi and high success rate of conservative management by sialendoscopy.
