[Semiology and etiology of anosmia: apropos of 306 patients].
Chemosensory dysfunction is relatively common. This article describes a series of 306 patients who presented with anosmia. We divided olfactory disorders into those associated with interruption of the transport of stimulus and those associated with damage to either peripheral or central nervous system structures. ⋯ They are generally older, with a mean age of 58 years and are predominantly female (78%). The loss of smell is sudden and anosmia is often accompanied by troublesome parosmias (50%). CT-scan is necessary for the evaluation of a smell dysfunction.
