Treatment of Olfactory Disorders After SARS - CoViD 2 Virus Infection.

Objective: The benefit of a nasal corticosteroid in the treatment of persistent post-infectious smell disorders is not as clear in previous studies as is assumed for olfactory training. This study would therefore like to describe the treatment strategies using the example of a persistent olfactory dysfunction as a result of a proven infection with SARS-CoViD-2-virus.

Methods: Twenty patients (average age of 33.

A New Method for Assessment of Retronasal Olfactory Function.

Objectives/hypothesis: The aim of the study was to develop a test for the assessment of retronasal olfaction in healthy participants and patients with olfactory disorders using "tasteless" powders.

Study Design: Prospective case-control series.

Methods: A total of 150 participants (110 women, 40 men, mean age = 40 ± 16 years) were recruited for this study; 100 were healthy controls and 50 were patients with olfactory loss due to infections of the upper respiratory tract (n = 25), idiopathic causes (n = 12), sinonasal disease (n = 7), and head trauma (n = 6).

Tract-based spatial statistics of the olfactory brain in patients with multiple sclerosis.

Purpose: To investigate diffusion tensor abnormalities, e.g. fractional anisotropy (FA), mean diffusivity (MD), and radial diffusivity (RD), in olfactory structures of multiple sclerosis (MS) patients using diffusion tensor imaging (DTI).

Treatment of chronic rhinosinusitis with pressure-pulsed corticosteroid inhalation.

Chronic rhinosinusitis may cause olfactory dysfunction and affects quality of life in patients. In a prospective study we investigated the effect of topical application of corticosteroids through pressure-pulsed inhalation as treatment option of chronic rhinosinusitis with olfactory disorder. Patients with sinonasal olfactory disorder according to the European Position Paper on Rhinosinusitis and Nasal Polyps (EP3OS) were allocated to the new nasal inhalation therapy or a systemic corticosteroid therapy, each receiving a corticosteroid course of 12 days.

Olfactory dysfunction in patients with idiopathic intracranial hypertension.

Objective: Although accumulating evidence suggests that a malfunction of the CSF system in idiopathic intracranial hypertension (IIH) may give rise to olfactory dysfunction, little objective knowledge is available at present about the olfactory capacity of patients with this condition.

Methods: Seventeen patients with IIH and 17 age- and sex-matched controls were included. The extended Sniffin' Sticks procedure was used to test odor threshold, discrimination, and identification (TDI).
