What is anosmia

Loss of the Sense of Smell
Anosmia (/ænˈɒzmiə/) is the inability to perceive odor or a lack of functioning olfaction—the loss of the sense of smell.

Anosmia may be temporary, but some anosmia (including traumatic anosmia) can be permanent.

Anosmia is due to a number of factors, including an inflammation of the nasal mucosa, blockage of nasal passages or a destruction of one temporal lobe.

Inflammation is due to chronic mucosa changes in the paranasal sinus lining and the middle and superior turbinates.
