Abstract
Two cases of antrorhinolitiasis are reported. Case 1. A 55 year old man, who was suffering from a blowout fracture, had a white antrorhinolith in his right ethmoid sinus (10×7×5 mm, 0.3g) Case 2. A 51 year old woman, complaining of right cheek swelling and nasal discharge had an antrorhinolith in her right maxiallary sinus (13×15×15mm. 1.3g). Rhinoliths in the ethmoid sinus are rare, and we had found only three other cases in the literature in Japan. Radiography, especially conventional and computer aided tomography are very useful in diagnosing antrorhinoliths.
