| Objective: The aim of this study was to evaluate the therapeutic efficiency of sialendoscopy-assisted operations in the treatment of submandibular gland stones.Methods: The data from twelve patients with sialolithiasis who were treated with sialendoscopy from August 2015 to May 2017 at the Department of Oral and Maxillofacial Surgery,School of Stomatology,China Medical University(Shenyang,China)were retrospectively reviewed.All of the patients underwent preoperative Emission Computed Tomography(ECT).The results revealed that the salivary glands exhibited normal or slightly reduced uptake and excretion dysfunction.Computed tomography(CT)examinations revealed stones located in the intraductal area near the glands or in the branches that could not be removed due to their deep locations within the mouth.All patients were under general anesthesia,endoscope was inserted,the stones were located intraductally using sialendoscopy,and a transcervical incision was made to remove the stones while preserving the submandibular gland.The postoperative healing and salivary gland function were observed at 1,3,6,and 12 months after surgery.Results: The stones were completely removed,and the submandibular gland was preserved in all twelve cases.The excretion function of glands were restored to normal(P<0.05).In 11 patients recovered well postoperatively,and there were no complications.However,a mucous cyst occurred in one patient at one months after surgery,after resection of the mucous cyst under local anesthesia,no other symptoms were reported.All patients in this study completely healed and had no recurrence of infection during the 6 to 15 months(mean 10.4 months)of follow-up.Conclusions: Our results suggest that sialendoscopy-assisted sialolithectomy is an effective and safe surgical technique for the removal of proximal and intraglandular submandibular gland stones. |
