Chulalongkorn Medical Journal


Foreign bodies in the sinus are uncommon and transorbital foreign bodies in the maxillary sinus are veryrare. We hereby described a case of a glass marble ball about 1.6 cm in diameter that penetrated into the rightmaxillary sinus through the orbital floor without globe rupture. The foreign body in the sinus should be removedto prevent further infection and other complications. In this case, the glass marble ball was removed by a transnasalendoscopic technique with a widened maxillary antrum after guarding of orbital ball upward in order to preventthe orbital injury. There were no immediate and long term postoperative complications.
