Transposition of Stensen’s duct in severe salivary duct stenosis – a case report

This case report presents interventional sialendoscopy treatment in a patient with chronic parotitis based on sialolithiasis and later Stensen's duct stenosis. After sialendoscopic sialolith removal, stricture of Stensen's duct in the distal part developed, with megaduct formation. On MRI, the parotid gland parenchyma was without present pathology. A transoral approach was chosen. Stensen's duct dissection, transposition, sialendoscopy of the proximal duct, and stenting were performed. After surgery, the patient's state improved, no more episodes of swelling were experienced. The stent was removed after 3 weeks. Six weeks after surgery, the neostoma stays functional with clear saliva secretion.
