Rhinoliths, also known as nasal calculi, are uncommon lesions that results from a chronic inflammatory response to complete or partial mineralised encrustation of intranasal foreign bodies. They are most commonly seen in children and cognitively impaired adults who accidentally insert foreign bodies into their nose. Less frequently, trauma, surgery and dental work, nasal packing material, and plugs of ointment may also promote the development of a rhinolith.
These lesions appear as a densely calcified mass in the nasal cavity, with displacement and expansion or destruction of the adjacent bony landmarks.
Some of the remote complications include perforation of the hard palate bony destruction, and expansion of the stone into the maxillary sinus, facial tetanus, or septal perforation.
History and etymology
The first published report of a calcified foreign body in the nose appeared in 1654, in which Bartholini described a stone-hard foreign body that had grown around a cherry stone.The term rhinolith was first coined in 1845 to describe a partially or completely encrusted foreign body in the nose.
