PurposeIntraoral removal of submandibular sialoliths is a surgical technique for the treatment of sialolithiasis and is reported to have excellent outcomes. In this study, we sought to determine the risk factors leading to complications of this procedure.Patients and MethodsThe medical records of 200 patients who had undergone intraoral removal of sialoliths between January 2006 and June 2015 were retrospectively reviewed. We used a telephone survey to check the postoperative symptoms. Dry mouth, wound infection, lingual nerve dysfunction, and recurrence were considered to be complications. Computed tomography (CT) scans of the neck were reviewed for location, shape, number, and size of the stone.ResultsThe number of patients who complained of a complication was 44. The incidence of complications was significantly higher in patients in whom the stone was located in the proximal region of the salivary duct (proximal group) than in those with middle or distally located stones (middle/distal group) (p < 0.05). The average stone size was larger in the proximal group; the operation time and length of admission were also longer in the proximal group, with a statistically significant difference (p < 0.05). Complaints of lingual nerve dysfunction were significantly higher in the proximal group than in the middle/distal group (p < 0.05).ConclusionPatients with proximally located stones had more complications, especially lingual nerve dysfunction, than those with middle/distally located stones. The former group also required a longer operation time and hospital stay.
