Olfactory dysfunction can result in substantial reductions in quality of life if left untreated. The presence of phantom smells, or phantosmia, is a clinically distinct olfactory dysfunction where patients sense odors when no odor source is present.1 The cause of phantosmia is not completely understood and has been most commonly associated with head trauma, psychiatric conditions, chronic rhinosinusitis, epilepsy, and a number of neurologic and neurodegenerative disorders.2
