These features suggest that anosmia could possibly be the consequence of a localized impairment of airflow conduction or of a sensorineural damage. Given that, to date, studies investigating olfaction disorders largely outnumber those focusing on other chemical senses, we will discuss the former with particular attention and provide a brief overview of the current literature on the latter. However, other inflammation-mediated mechanisms, involving focal mucosal swelling and airflow obstruction could also possibly occur, and the hypothesis of a direct infection of olfactory sensory neurons deserves additional investigations.
