Rhinolithiasis: the importance of flat panel detector-based cone beam computed tomography in diagnosis and treatment.

Rhinolithiasis is a disease caused by deposition of organic and inorganic compounds in the nasal cavity. A nidus may be endogenous or exogenous. Rhinoliths are uncommon and often an asymptomatic condition diagnosed accidentally during a routine examination; but sometimes they may cause complications such as unilateral nasal obstruction, fetid rhinorrhea, or epistaxis. This article describes a case of rhinolith involving a 21-year-old female. The flat panel detector-based cone beam computed tomography (FPD-CBCT) findings, differential diagnosis, and treatment in a case of rhinolith are presented.
