Abstract The sense of smell provides people with valuable input from the chemical environment around them. The human sense of smell generally fails in three ways; one is an intensity reduction and the other two are the quality of changes. Smell disorders can be classified into central or peripheral depending on their origin. Central causes can be related to an area of hyper-functioning brain cells generating this odor perception, thus olfactory distortions have also been observed with epilepsy… 
Hidden consequences of olfactory dysfunction: a patient report series
TLDR
Olfactory dysfunction is a serious condition for those affected by it and it deserves more attention from doctors who treat affected patients as well as from scientist who research treatment options.
Induction of smell through transethmoid electrical stimulation of the olfactory bulb
TLDR
A pilot study was performed to determine the feasibility of inducing smell through artificial electrical stimulation of the olfactory bulbs in humans, and found it to be feasible.
Posttraumatic olfactory dysfunction.
Anosmia: Differential Diagnosis, Evaluation, and Management
TLDR
The differential diagnosis, workup, and current treatment strategies of anosmia and smell disorders are reviewed, with a focus on improving both the diagnosis and reporting of treatment outcomes of olfactory training.
Consequences of gaining olfactory function after lifelong anosmia
TLDR
A rare case in which a patient has gained her smell after lifelong anosmia is presented, which shows an electrophysiological signal for two unimodal odorants.
The role of surgery in the management of phantosmia
TLDR
The diagnostic features of peripheral and central phantosmia are presented, as well as the surgical technique utilized in this institution and the outcomes of the patients after such treatment are described.
Diseases of the nasal cavity
Olfactory cocainization is not an effective long-term treatment for phantosmia.
TLDR
Following topical cocainization, a remarkable delay of hours to days in the return of olfactory ability is observed, and the possibility that phantosmia is related to a central processing problem is suggested.
Parosmia and Neurological Disorders: A Neglected Association
TLDR
These clinical cases show how the correct diagnosis of parosmia can represent the tip of the iceberg of important underlying neurological disorders and be a good prognostic indicator of their progression or recovery.

Diagnosis and Treatment of Distorted Olfactory Perception
TLDR
Although patients with troposmia, phantosia, and hallucinations may have decreased ability to perceive odorants, their main concern is that perceived odors are distorted or different from what they remember.
Distortion of olfactory perception: diagnosis and treatment.
TLDR
Treatment for phantosmia includes assurance with no active therapy, topical medications, systemic medications, anesthesia to parts of the nose and, rarely, referral for surgical excision of olfactory neurons.
Fish-odor syndrome presenting as dysosmia.
TLDR
A patient who had perceived an unpleasant odor or taste for at least 20 years was described, and testing at the Monell-Jefferson Chemosensory Clinical Research Center, Philadelphia, Pa, confirmed that she had trimethylaminuria.
Patterns of non-conductive olfactory disorders in eastern Austria: a study of 120 patients from the Department of Otorhinolaryngology at the University of Vienna.
TLDR
With increasing age women seem to suffer more often from chemosensory dysfunction than men, which may be related to hormonal factors, and those older than 50 years seem to have a higher risk of developing olfactory disorders.
Fluctuating olfactory sensitivity and distorted odor perception in allergic rhinitis.
TLDR
There appears to be a continuum of duration and severity of olfactory loss in allergic rhinitis that parallels increasing severity of nasal-sinus disease.
Euosmia: A rare form of parosmia
TLDR
The case of a female with post-infectious hyposmia who reported a pleasant parosmia to selected odorants is reported, which is a rare clinical presentation called euosmia.
Distorted odorant perception: analysis of a series of 56 patients with parosmia.
TLDR
The series of patients with parosmia presented herein, the largest in the literature, permits a clinical description of this rare olfactory abnormality.
Correlation of olfactory function with changes in the volume of the human olfactory bulb.
TLDR
The human OB is a highly plastic structure that responds to individual changes in olfactory status and is demonstrated in a longitudinal study for the first time to the authors' knowledge.
A study on the prognostic significance of qualitative olfactory dysfunction
TLDR
The current data indicate that occurrence of parosmia or phantosmia has little prognostic value, and insights into qualitative olfactory dysfunction are regarded to be significant in the counseling of patients with Olfactory loss.
Impact of olfactory impairment on quality of life and disability.
TLDR
Patients reporting persistent olfactory impairment after previously documented olfatory loss indicate a higher level of disability and lower quality of life than those with perceived resolution of olfactic compromise.
