Background: Patients undergoing any type of nasal surgery may experience degrees of postoperative olfactory dysfunction. We sought to investigate "when" the olfactory function recovers to its preoperative levels. Methods: In this cohort design, 40 of 65 esthetic open rhinoplasty candidates with equal gender distribution, who met the inclusion criteria, were assessed for their olfactory function...

The first tier of the test battery is an olfactory screening test consisting of a 12-odor identification test. This test discriminates anosmia from hyposmia and normosmia. As a second tier, the Threshold–Discrimination–Identification Test offers a more extensive analysis of olfactory deficits (TDI score, Sniffin’ Sticks). A growing pool of normative data (Kobal et al., 2000) is now available an...

BACKGROUND The factors affecting the correlation between Parkinson disease (PD) and depression have remained unclear. OBJECTIVES We assessed the prevalence of depression among patients with PD and the association between PD-related variables and depression severity. PATIENTS AND METHODS This is a cross-sectional study performed in Kermanshah Province of Iran. Sampling was based on recruitme...

OBJECTIVE Kallmann syndrome (KS) is a genetic disorder with the distinctive features of hyposmia or anosmia and hypogonadotropic hypogonadism. Though hyposmia/anosmia can be evaluated by both objective and subjective smell tests, there is no study comparing these two methods in KS. The aim of the present case series was to discuss the results of objective and subjective smell tests and compare ...

Background: Isotretinoin is a synthetic analog of vitamin A. Recent studies support a role for retinoic acid in the recovery of olfactory function following injury in mice. Objective: This study aimed at determining the effect of isotretinoin on olfactory function in patients who have acne and are otherwise healthy. Methods: Forty-five patients (aged 25-40 years) with acne were included in ...

In the clinical diagnosis of olfactory function, 2 quantitative extremes of either lost or normal olfactory function are in the focus while no particular attention is directed at the interval between the 2 main diagnoses of "anosmia" or "normosmia", respectively. We analyzed the modal distribution of olfactory scores with the intention to describe a complex human olfactory pathology in a unifyi...

The objective of this study was to assess a cohort of Gaucher disease patients and their heterozygous carrier relatives for potential clinical signs of early neurodegeneration. Gaucher disease patients (n = 30), heterozygous glucocerebrosidase mutation carriers (n = 30), and mutation-negative controls matched by age, sex, and ethnicity (n = 30) were recruited. Assessment was done for olfactory ...
