Smell training for olfactory loss of all types is a well-recognised treatment, and the typical regimen of rose, clove, lemon and eucalyptus is frequently used. This study looks to compare using eight essences rather than four to see if this could improve the recovery from olfactory dysfunction. In the advanced olfactory training of set, the patients used the classical odours but additionally citronella, mint, vanilla and cedar wood. This is an ambitious multicentre study, with 80 patients ultimately enrolled into the trial. It is also the first to evaluate an alternative method of olfactory training for patients with post COVID-19 smell loss. Overall, the authors found an improvement in olfactory function in both groups, but no statistically significant difference between the classical or the advanced olfactory training groups. Whilst perhaps disappointing not to demonstrate a faster or more superior response with the enhanced smell training, this is a welcome study adding more ideas to the field of olfactory recovery.
A new idea for olfactory recovery, but not the evidence to support it
