title: Surgeon-performed ultrasound and transfacial sialoendoscopy for complete parotid duct stenosis.
abstract: A 57-year-old man presented with a 16-month history of right parotid swelling since undergoing a transoral sialolithotomy of the parotid duct. An ultrasound and a computed tomography scan showed a 6 cm-long dilated parotid duct without evidence of sialolithiasis or tumor mass. The complete Stensen's duct stenosis that was found was managed by a surgeon-performed ultrasound-guided transfacial needle catheterization of the dilated parotid duct, anterograde sialoendoscopy, recanalization of the duct, and stent placement. At 15 month follow-up, the patient reported no recurrent facial swelling or discomfort. Surgeon-performed ultrasound, combined with sialoendoscopy, can provide unique advantages for managing parotid duct stenosis and obstructive sialadenitis.
