  Fig. 1. Surgical procedure of transoral sialodochoplasty. (A) The stenotic portion and accompanying megaduct (asterisk) are pulled into the oral cavity after circumferential incision around the papilla and dissection along the parotid duct. (B) The stenotic lesion (arrow) is exposed with an incision onto the ductal wall. (C) Excised distal duct with stenotic lesion. (D) Creation of a neo-orifice by suturing the wall of the megaduct onto the buccal mucosa.

  Fig. 2. Preoperative and postoperative magnetic resonance (MR) sialographic findings of parotid duct stenosis with secondary dilated megaducts, before and after transoral sialodochoplasty. (A) Preoperative MR sialographic image depicts a parotid duct stricture with an accompanying megaduct (asterisk). (B) Arrow indicates visualization of the distal duct after surgery, suggesting improvement in saliva excretion through the previous stricture site.
