Participants
Patients who underwent salivary ductal surgery (sialendoscopy with
sialodochoplasty) from March 2017 to March 2019 were retrospectively
identified from our database. Stenosis of salivary gland ducts was
objectively confirmed by either ultrasonography or magnetic resonance
(MR) sialography. Patients with type 2 stenosis in the Stensen duct,
which indicates a focal stricture and accompanying megaduct on
preoperative radiologic evaluations, were then selected. Patients who
did not respond to conservative care, including gland massage, pain
medications, and sialagogues, received salivary ductal surgery. Among
them, patients with accompanying sialolithiasis or any other underlying
causes, such as Sjogren’s or previous radioiodine therapy, were
excluded; only cases of idiopathic salivary duct stenosis were finally
enrolled in this study. Patients who underwent sialendoscopy or any
other salivary gland surgery within the past 1 year were also excluded.
