Abstract
Two cases of rhinolithiasis are herein reported. In the first case, a Yellow-brown mass in the left nasal cavity of a 28-year-old female was removed in a piecemealy fashion under a local anesthesia while the uncleus could not be found. In the second case, an operation revealed a bad smelling black-brown mass in the right maxillary sinus of a 80-year-old male. A histopathological examination of the calculi revealed that the problem was caused by a fungus ball. We analyzed 153 similar cases of rhinoliths previously reported in the Japanese literature and also discussed the origin of these rhinoliths.
