“…Different studies have suggested that the smell training is promising (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21) . Olfactory improvement through olfactory training was investigated in patients with smell dysfunction (5)(6)(7)(8)(9)(10)(11)(12)(13)19) , as well as in older (17,20) , and younger healthy people (14,21) . However, given that not under all circumstances the training proved to lead to significant smell improvement (e.g.…”

The neural plasticity of the olfactory system o ers possibilities of treatment in terms of stimulation of the sense of smell, and different studies have suggested e ectiveness of smell training, i.e., daily exposition to certain odors. To obtain reliable and precise estimates of overall treatment bene t on the olfactory function, we meta-analyzed the e ects of smell training reported in 13 previous studies. We analyzed the smell training e ectiveness across three di erent olfactory abilities-smell identi cation, discrimination and threshold for odor detection. We found a signi cant, positive e ect of olfactory training for all olfactory abilities, with large e ects of training on identi cation, discrimination and TDI-score and small-to-moderate e ect in the case of threshold for odor detection. Interestingly, the pattern of results di ered across Sni n' Sticks subtests depending on the origin of participants' smell disorder, and the smell training duration in uenced its e ectiveness in the case of identi cation and the TDI score. Although the exact mechanism of olfactory recovery following the smell training still requires further investigation, our meta-analysis showed that such training should be considered an addition or alternative to existing smell treatment methods.

“…Recently, a number of papers point to new treatment options in olfactory loss giving hope to deprived patients. Olfactory training has been shown to be a promising therapeutic approach with which to improve olfactory skills in post-infectious anosmic patients but also in patients with neurogenerative diseases (22)(23)(24) . Insulin signalling has been implicated in olfactory function and nasally administered insulin can improve smell in post-infectious olfactory patients (21) .…”

Already for years we have ample evidence of the severe impact of allergic and non-allergic rhinitis and maybe even more rhinosinusitis on quality of life of our patients and the severe costs these diseases inflict on society. Despite this evidence we have difficulty convincing the politicians, health insurance companies and the public that more attention, research and money is needed to prevent these diseases to occur and to further prevent the sometimes serious sequalae of the disease.
