Abstract: Objective To investigate the clinical effects of sialoendoscopically-assisted sialolithectomy for the sialolithiasis in the hilum of the submandibular glands.Methods Between December 2005 and March 2011, treated 80 cases of radiography-verified sialiolithiasis in the hilum of the submandibular glands,The patients included 42 males and 38 females aged from 13 to 68 years.All these patients underwent sialoendoscopic observation and sialoendoscopically-assisted sialolithectomy and were followed up periodically for 3-6 months after operation. The success rate of stone removal,postoperative complications and clinical effects were analysed.Results The stones were completely removed in 71 cases,and almost completely removed in 5 cases,with a successful rate of 95% (76/80).Among 76 successful cases,8 were treated by basket entrapment,59 by intraoral open surgery and 9 by both of these two techniques.Within 3-6 months' follow-up,1 case suffered temporary lingual nerve parenthesis and two suffered ranula formation.Conclusions Sialoendoscopically-assisted sialolithectomy is a safe and effective gland-preservation technique for the patients with the hilum of the submandibular glands.
