Key-points:
- COVID-19 affects both gustatory and olfactory functions.
- SARS-coronavirus affects more than one cranial nerves, namely the
chorda tympani, the glossopharyngeal and the trigeminal nerves.
- It seems to disturb not only the peripheral receptors related to the
chemical senses, but also the regeneration of their peripheral nerve
fibers.
- The majority of the patients reports an improvement of taste and
odour-disturbances within 4 weeks.
- The functional improvement of taste acuity does not correlate directly
to the morphology (including the vascularization) of fPap.
