	Treatment of Parosmia
		There is some evidence that parosmia may, at least in some patients, be caused by dysfunction of olfactory neurons whose axons run from the olfactory mucosa (high in the nasal cavity) to and through the cribriform plate (into the brain).
		The subjects of the study were 8 patients with parosmia for whom blocking the affected nostril(s) would stop the unpleasant odor (some individuals with parosmia/phantosmia experience the unpleasant odor whether or not there is air flowing through their nostrils).
		Although the surgery was intended to relieve parosmia by eliminating all possibility of olfactory reception within the affected nostril, these patients recovered their ability to smell things -- apparently either some of the olfactory neurons were spared or there was regeneration of olfactory nerves.

	Parosmia and Phantosmia
		Parosmia involves a distortion of the sense of smell -- the affected person reports smelling something other than the scent which is present -- for example, the person sniffs a banana but it smells like rotting flesh instead of a banana.
		Among the unpleasant scents often reported by those suffering from parosmia or phantosmia are the smells of death (rotting flesh), feces, vomit, garbage, and smoke.
		Although I got hundreds of hits when I searched for "parosmia," most of these were pages describing various mediations (including two that I take daily) for which parosmia is listed as a possible side effect.

	Smell (Site not responding. Last check: )
		Olfactory disorders consist of temporary or permanent: complete or partial smell loss (anosmia or hyposmia) and parosmias (perverted smells dysosmia or phantom smells phantosmia) (Mott and Leopold 1991; Mott, Grushka and Sessle 1993).
		Parosmias developing as the patient recovers from injury may indicate regrowth of olfactory tissue and herald return of some normal smell function.
		Parosmias occurring at the time of injury or shortly thereafter are more likely due to brain tissue damage.

		We investigated the frequency and prognostic significance of qualitative olfactory dysfunction (parosmia, phantosmia) in a retrospective patient based study.
		Parosmia was most frequent in patients with postinfectious olfactory loss (56%), and less frequent in idiopathic, posttraumatic, sinunasal disease with frequencies of 10, 14, and 28%, respectively.
		Regarding qualitative olfactory dysfunction, 29% of those patients reporting parosmia reported relief of this symptom after an average of 12 months, whereas 53% of phantosmic patients lost phantosmia during the observation period.

	You Smell!: A Look into Olfactory Hallucinations
		Parosmia is a distortion of the olfactory sense.
		People with parosmia report smelling scents that are incongruent with the olfactory stimuli presented.
		For phantom limbs this is a simple matter, there are no sensory inputs from the amputated limb and the brain thinks there should be, but for parosmia and phantosmia there is no reason for the signal to be incongruent.
