3D CBCT reconstruction as an adjunct in the management of sialectasis of Stensen’s duct: a case report and review of literature

Sialectasis of Parotid gland is an infrequent condition, and characterized as dilatation of a segment of Stensen’s duct which generally occurs as a consequence of intra-ductal distal obstruction caused by sialoliths, intra-ductal papillomas or partial strictures of the duct. Current imaging technologies including sialendoscopy, sialography, magnetic resonance imaging (MRI), or computed tomography (CT) have their unique diagnostic profile and offer several advantages including cost-effectiveness, availability, and lower radiation dosages. However, despite these advantages, 3-Dimensional Cone Beam Computed Tomography (3D CBCT) has been in favor for the diagnosis of salivary calculus because of its superior diagnostic performance and favorable information-to-radiation-dose ratio. Herein, we presented a case of a patient with sialectasis of the Stensen’s duct in whom the cause of the dilatation was not clear. The case was reported for its uncertain etiology and the use of 3D CBCT reconstruction as an adjunct in the diagnosis and management of a relatively rare lesion. In the following case report, a 46-year-old male patient diagnosed with sialectasis of Stensen’s duct was treated with integrated 3D CBCT software and conservative surgical approach. Comprehensive treatment planning resulted in restoration of normal facial symmetry and smile form with no signs of relapse. In conclusion, 3D CBCT images allow proper visualization and localization of the lesion and may help in selecting the best approach for surgical intervention, which can altogether influence the management of the patient substantially.
