[Diagnosis of olfactory disorders].

Alongside a structured case history, the measurement of olfactory function and diagnosis of olfactory dysfunction is of great clinical importance. Validated and established methods have been developed to this aim. The "Sniffin' Sticks" test battery is an easy-to-use tool for assessing olfactory function. Recording of olfactory event-related potentials is a more objective approach, which is particularly important in medicolegal cases. Imaging techniques such as MRI and CT provide additional information in the diagnosis of olfactory disorders. The latter techniques enable the anatomical structures of the skull and brain with the areas relevant to olfactory function to be evaluated.
