title: Incidental 'ethmoid sinolith'--an unusual cause of frontal recess obstruction.
abstract: We report a case of a middle aged, hypertensive man who presented with nasal obstruction, sneezing spells, headache and nasal discharge of long duration. On evaluation, he was diagnosed to have a deviated nasal septum with allergic rhinosinusitis with sinonasal polyposis. CT of the paranasal sinuses revealed a hyperdense, oval structure suggestive of a sinolith in the right anterior ethmoid sinus. The patient underwent septoplasty with right Draf 2B procedure and extraction of the sinolith from the ethmoid sinus.
