Two cases of rhinoliths in a male aged 18 years and a female aged 52 years who complained of nasal obstruction with mucopurulent and sometimes, bloodstained discharge were reported. The fresh specimens of nasal calculi removed in the former case weighed 4.5 grammes and 3.0 grammes in the latter.<BR>In the scanning electron micrographs the core like as nucleus with furrow and polous structure were found.<BR>Electron probe X-rays microanalysis showed that S element was concentrically detected in the core and furrow, while Ca, P, Mg, Si, Al and Na levels were recognized much more highly in the surrounding polous or solid parts compared with that of the nuclei.<BR>From these ultrastructural characteristics and chemical composition, the genesis of rhinoliths were discussed.
