Abstract

Olfactory disorders are fairly common in the general population. Exploration, on the other hand, is seldom performed by ENT specialists, even in reference centers. There may be three reasons for this: this particular sensory modality may seem unimportant to patients and/or physicians; available treatments may be underestimated, although admittedly much yet remains to be done; and olfactory exploration is not covered by the national health insurance scheme in France. Advances in research in recent decades have shed light on olfactory system functioning. At the same time, several techniques have been developed to allow maximally objective olfactory assessment, as olfactory disorder is sometimes the first sign of neurodegenerative pathology. Moreover, objective olfactory assessment may be needed in a medico-legal context. The present paper updates the techniques currently available for olfactory exploration.
