In two cases of chronic sinusitis, a thumb-sized concretion was noticed in the maxillary sinus. The clinical feature and course of these cases were reported. The main symptoms of the first case were muco-purulent nasal discharge and nasal obstruction, and of the second case nasal obstruction and tenderness on the buccal region. X-ray examinations of these cases revealed a well-defined shadow in the affected maxillary sinus. In each case the concretion was removed with a procedure of maxillotomy and the postoperative course was uneventful. The chemical examination of these concretions revealed that one of these was mainly composed of calcium carbonate, and phosphorus, and the other of calcium carbonate and seconderycalcium phosphate.
