Key points
- Parosmia is associated with clinically relevant improvements in
discrimination and identification function in patients with smell loss
receiving olfactory training.
- Clinically relevant recovery of overall olfactory performance was more
likely in those that had lower baseline olfactory function at initial
visit and in postinfectious smell loss compared to posttraumatic or
idiopathic causes.
- Recovery of suprathreshold olfactory function discrimination and
identification was distinct from threshold improvements.
