Background and Objectives : Proximal submandibular stone is not a rare disease. The aimof this study is to evaluate the surgical outcomes of 3 different ways to treat proximal submandibularstone: intraoral removal of stone (IORS) with sublingual gland (SLG) resection, IORSwithout SLG resection and submandibular gland (SMG) resection.
Subjects and Method : We prospectively reviewed the surgical outcomes of IORS with SLGresection group (22 patients), IORS without SLG resection group (35 patients) and SMG resectiongroup (22 patients). To evaluate the surgical outcomes, we analyzed the location and size ofstones, mean operation time, mean hospital stay, mean postoperative degree of pain based ona visual analog scale (0?10), and incidence of complications.
Results : There were no significant differences between the mean diameter of stones and lengthfrom the hilum to stones. The mean operation time was shorter in the IORS without SLG resectiongroup than that in IORS without SLG resection group, and was significantly shorter thanthat of the SMG resection group. The mean hospital stay of the IORS without SLG resectiongroup was also shorter than that of IORS with SLG resection group, and was significantly shorterthan the SMG resection group. IORS without SLG resection group felt less pain than IORSwith SLG resection group and SMG resection group. Four patients who underwent IORS withoutSLG resection experienced transient and mild SMG swelling, and mild paresthesia wasnoted on the same side. All patients recovered within 3 months. Intraoral removal of proximalSMG stones exhibited several advantages over SMG resection in terms of hospital stay, meanoperation, time and postoperative pain.
Conclusion : Based on our results, we suggest that IORS without SLG resection be selected asthe primary procedure for the removal of proximal submandibular stones rather than SMG resection.
