Abstract

Background: Surgical treatment for submandibular gland stones varies depending upon the site and size of the submandibular gland. With the transoral method, nerve damage and intraoperative bleeding in the direct incision over the hilar stones are possible. We used the lateral oral floor approach and report our procedure and the associated complications. Methods: Surgery was performed under general anesthesia. A 2–3 cm longitudinal mucosal incision was approximately parallel and outside of the Wharton’s duct. The surrounding tissues were peeled away and the incision was made just above the stone and the stone was extracted. Results: 2 males and 5 females enrolled in this study, all stones were removed without leaving residual stone fragments. One patient had slight hypoesthesia on one side of the tongue, which resolved in 1 month Conclusions: Hilar stone excision from the submandibular gland was performed using the lateral oral floor approach. There were few complications and the technique seemed to be effective for relatively large hilar stones.
