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.
