Olfactory Training: Recommendation Frequency Amongst Rhinologists.

Despite the prevalence and health impact of olfactory dysfunction (OD), therapeutic options remain limited. One potential therapy is olfactory training (OT), where patients repeatedly sniff a small set of odors over several weeks with the goal of improving olfactory function. Although double-blinded, placebo-controlled clinical trials supporting the efficacy of OT are lacking, anecdotal evidence suggests that the procedure is widely recommended to patients with anosmia or other olfactory disorders.
