The effects of comorbidities on the change of taste and smell in COVID-19 patients

[The sound and musical preferences of tympanic chord]

The tympanic chord is a part of the 7th cranial nerve (facial nerve), from which it branches off, runs through the middle ear and then joins the lingual nerve, a part of the 5th cranial nerve (mandibular nerve/trigeminal nerve). Despite its course through the ear, the tympanic chord does not carry auditory fibers, but rather sensory and parasympathetic fibers to the front part of the tongue and to the salivary glands.The cranial nerves V and VII have a common phylogenetic origin, establishing a close relationship between auditory and gustative sense.In German language "Geschmack" means both gustative sense and the preference for different ways of thinking or styles in music, art or fashion. "Musikgeschmack" is the preference for special music styles or composers. "Musikgeschmack" therefore forms an interface between the anatomy of the tympanic chord and music preferences.The effect of parallel processing of music and taste is used, for example, in music therapy or as part of marketing strategies. But it could also be used to treat Covid-19 patients who suffer from a loss of sense of smell and taste. However, there are still no studies on this specific question.
