Management involves identification of the same, removal of any foreign body from the maxillary sinus, if present, followed by appropriate flap for closer. A case is presented when a gutta percha (GP) point was accidentally dislodged into the right maxillary sinus during preliminary diagnosis of the oro-antral fistula. The surgical management of the case is described and is the appropriate treatment plan.展开更多
