Objectives: Rhinolithiasis is the presence of mineralized and calcareous formations located in the nasal cavity. They have rare occurrence and can be easily confused with infection or obstruction of tipper airways. If they are undetected for a long time, they may grow large enough to cause of nasal obstruction, mimicking sinusitis. Seven cases of rhinolithiasis were presented, and their diagnosis was made by rigid endoscopic nasal examination. Also computerized tomography scan was used to describe the size and site of the rhinoliths accurately. Our purpose was to determine the role of rigid nasal endoscopy in the diagnosis and the treatment of rhinolithiasis.
