摘要: Abstract Transoral removal of stones for the treatment submandibular sialolithiasis has been popularised, even in hilum. Without sialodochoplasty after surgical retrieval, affected glands seem to recover well functionally, without sialodochoplasty. However, anatomical changes structural recovery have not fully studied. We investigated outcomes and salivary duct system transoral hilar using postoperative sialography. enrolled 28 patients (29 sides) who had sialodochoplasty, prospectively analysed 3 months 12 postoperatively found 23 ducts (79%) recovered with a normal size, while 4 (14%) developed saccular dilatation one (3%) partially stenosed. Saccular larger than 10 mm diameter, but no recurrent symptoms. By months’ follow up, stone formed severe adhesions that caused stenosis, this patient is an effective good restoration flow.
