Definition: When there is a long-standing foreign body in the nose it is surrounded by granulation tissue and it acts as a nucleus for concretion to occur. It eventually gets coated with calcium and magnesium phosphate and carbonate to form a Rhinolith. Aetiology:
- Age: Can occur in any age group but is more common in children.
- Foreign bodies, blood clots, inspissated pus.
- Rhinorrhea: Unilateral, Purulent, foul smelling.
- Nasal obstruction: Unilateral.
- Rhinolith usually seen on anterior rhinoscopy.
Site: Rhinoliths are usually formed near the floor of the nose.
Treatment: Removal of nasal rhinolith usually done under general anesthesia. FESS may be required if there is any secondary sinusitis. Also, endoscopic clearance of the Rhinolith particles is necessary.
