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.
