title: Rhinolithiasis: an unusual cause of nasal obstruction.
abstract: Rhinoliths are foreign bodies of the nose, which may be encountered during the course of a routine examination. If undetected for a long time, they may grow large enough to cause symptoms of nasal obstruction, mimicking sinusitis. We report four patients with rhinoliths presenting with diverse clinical findings. Removal was easy and uneventful in all cases.
