RHINOLITHS, or nasal calculi, are comparatively rare. Thompson1 mentioned that 300 cases were reported in the literature up to 1921. Probably not over 25 cases have been reported since that time. It is believed, therefore, that the occurrence is steadily diminishing. They are divided into true and false types. The false type has as a nucleus some type of foreign body such as beads, nut shells, or buttons. The true type has a nucleus of dried mucus, blood, crusts, leucocytes, or bacteria.
Chemically2 these stones consist of the inorganic salts of calcium, magnesium, and sodium, chiefly phosphates, carbonates, and chlorides. They are usually a reddish gray to dark brown or black. They may be hard and brittle, or soft and friable. They vary from a calculus the size of a small pebble to one weighing 116 gm.3
