[Sialoendoscopically-assisted sialolithectomy for the hilar stones of the Wharton's duct].
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.
