OBJECTIVES/HYPOTHESIS The aim of this study was to evaluate the effects of olfactory training (OT) on olfactory function in patients with persistent postinfectious olfactory dysfunction (PIOD). [...] Key MethodSTUDY DESIGN Randomized, single-blind, controlled, multicenter crossover study. METHODS Twelve tertiary university medical centers participated. Investigations were performed at three visits (baseline, after 18 weeks, and after 36 weeks), including only subjects with PIOD of <24-months duration.Expand

Efficacy of olfactory training in patients with olfactory loss: a systematic review and meta‐analysis
TLDR
Olfactory loss is a challenging clinical problem with few proven therapeutic options, and early experimental results suggest that this novel therapy may be an effective intervention for olfactory dysfunction of multiple etiologies. Expand
Postinfectious olfactory loss: A retrospective study on 791 patients
TLDR
This work aimed to assess the prognostic factors for recovery in a large sample of 791 patients with postinfectious olfactory disorders, and found no smoking, alcohol, or drug abuse habits were associated with recovery. Expand
Rehabilitación olfatoria en pacientes con anosmia
TLDR
To observe the effects of olfactory training in patients with anosmia, evidence that repeated exposure to odorants produces relieve of some Olfactory disorders is studied. Expand
Modified olfactory training in patients with postinfectious olfactory loss
TLDR
This prospective study investigated whether the effect of OT might increase through the use of more odors and extension of the training period. Expand
Effectiveness of olfactory training on different severities of posttraumatic loss of smell
TLDR
The focus of this work was to assess effects of olfactory training (OT) in posttraumaticOlfactory loss patients through several metrics including psychophysical, Olfactory bulb volume, and functional magnetic resonance imaging. Expand
Examination of olfactory training effectiveness in relation to its complexity and the cause of olfactory loss
TLDR
This work examined whether the complexity of OT, namely alteration of odor quantity and quality, increases its effectiveness and found that it does. Expand

TLDR
A comprehensive review of PVOD treatment options is provided and evidence‐based recommendations for their use are provided. Expand
The use of platelet‐rich plasma in treatment of olfactory dysfunction: A pilot study
TLDR
This novel pilot study evaluated the role of PRP on olfactory neuroregeneration in patients with hyposmia and found its anti‐inflammatory and neuroprotective effects were beneficial. Expand
Is Olfactory Training Effective Treatment for Postinfectious Smell Loss?
TLDR
Olfactory training has shown promise with improvement of olfactory function in select patients who undergo repeated exposures to various odors in a structured paradigm, and this review summarizes pertinent studies assessing the effectiveness of OT in PISL. Expand

TLDR
Treatment with the antibiotic minocycline, which has been shown to act as an antiapoptotic agent, is thought to accelerate improvement of olfactory function. Expand
Effects of olfactory training in patients with olfactory loss
TLDR
The aim of this investigation was to determine whether patients with olfactory loss would benefit from “Training” with odors in terms of an improvement of their general Olfactory function and to produce both an improved sensitivity towards the odors used in the Training process and an overall increase of o aroma function.

TLDR
The χ2 test revealed a significantly better outcome in olfactory function in patients undergoing acupuncture compared with patients receiving vitamin B complex, suggesting TCA possibly offers a new therapeutic regimen for post-viral dysosmia. Expand
Recovery of olfactory function following closed head injury or infections of the upper respiratory tract.

It showed that the rate of improvement of olfactory function was significantly higher in patients with post-URTI dysosmia compared with Patients with posttraumatic dysosia and the factor "sex" had no significant effect on recovery of smell function. Expand
Long-term follow-up of olfactory loss secondary to head trauma and upper respiratory tract infection.
TLDR
These findings for patients with head trauma are consistent with other reports of recovery of (or improvement in) olfactory function after trauma-induced loss, and indicate that improvement in o aroma function occurs, but the improvement may take several years. Expand

Investigation of the potential therapeutic effects of α‐lipoic acid in olfactory loss following infections of the upper respiratory tract found possible mechanisms of actions include the release of nerve growth factor and antioxidative effects, both of which may be helpful in the regeneration of Olfactory receptor neurons.
