Abstract:
The article describes our exploration of a sialendoscopy-assisted transfacial sialolithotomy approach to intraparenchymal stones in the submandibular gland with gland preservation. Five patients with large intraparenchymal stones in the submandibular gland were included. Ultrasonography and computed tomograms (CT) were performed to locate the stones. As the large stones failed to be retrieved during endoscopy, patients were treated by a transfacial lithotomy approach with sialendoscopy. The glands were preserved in all cases. This approach can be considered an optional technique for the treatment of large intraparenchymal stones in the submandibular gland that fail to be removed during a transoral procedure.
