Figure 1. Surgical procedure of transoral sialodochoplasty. A. 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. Stenotic lesion (arrow) is exposed with an incision onto the ductal wall. C. Excised distal duct with stenotic lesion. D. Creation of neo-orifice by suturing the wall of the megaduct onto the buccal mucosa.
Figure 2. Post-operative changes in a neo-orifice after transoral sialodochoplasty. A. Immediately after operation. B. Post-operative 1 month. C. Post-operative 3 months. Arrow indicates formation of neo-papilla.
Figure 3. Pre- and postoperative magnetic resonance (MR) sialographic findings of parotid duct stenosis with secondary dilated megaducts between pre- and post-transoral sialodochoplasty. A. Pre-operative MR sialographic image depicts parotid duct stricture with an accompanying megaduct (asterisk). B. Arrow indicates visualization of the distal duct after operation, suggesting improvement in saliva excretion through the previous stricture site.
