PP165: Advantages of intraoral removal over submandibular gland (SMG) resection for proximal submandibular stones

Abstract

Purpose The purpose of our study is to compare surgical outcomes of proximal submandibular stones between intraoral removal and traditional SMG resection. Materials and methods Forty-four patients were diagnosed with proximal submandibular stones by Neck CT. They are randomly assigned to either the intraoral removal of stone (IORS) group or the conventional SMG resection (SMGR) group. A single surgeon performed all of the operations. Results Means stone size was significantly smaller in IORS group than SMGR group by 5.2–9.0 mm.Means distance from hilum of both groups showed no significant difference. Means distance from hilum of both groups showed no significant difference. Mean operation time was significantly shorter in IORS group than that of SMGR group by 51.1 versus 83.2 min. Mean hospital stay was also significantly shorter in IORS group by 2.6–5.3 days. Mean postoperative pain estimated by VAS was significantly lower in IORS group by 3.0 versus 4.3. Conclusions Intraoral removal of proximal submandibular stones has several advantages over SMG resection in terms of hospital stay, mean operation time, and postoperative pain. Also there were no reported complications after the operations. We therefore recommend that our intraoral removal method replace SMG resection as the primary procedure for the removal of proximal submandibular stones.
