Conclusions
This study adds to the current literature in three important ways.
First, parosmia was associated with clinically relevant recovery of
suprathreshold olfactory function after OT, which highlights the need to
further raise awareness for symptoms of qualitative OD in patients with
smell loss. Secondly, it provides valuable insights into factors that
modulate clinically relevant recovery of olfactory function after OT.
These variables can further be used in counselling of patients to
calibrate expectations and outcomes more appropriately. Thirdly, it adds
evidence to the idea that the comprehensive analysis of different
olfactory components, such as threshold and suprathreshold functions
during psychophysical testing are indispensable when evaluating the
human sense of smell.
