Defining the burden of olfactory dysfunction in COVID-19 patients.

The sense of smell has a high impact on the quality of life. The aim of the present study was to investigate olfactory dysfunction in patients with obstructive sleep apnoea syndrome (OSAS) and correlate the severity of disease with olfactory dysfunction. The relationships between nasal obstruction, nasal mucociliary cleareance and olfactory tests were also evaluated. Sixty patients with a diagnosis of OSAS were enrolled and underwent olfactory function evaluation. In all patients olfactory performance was tested with the Sniffin’ Sticks method.

Objective: To evaluate olfactory function and clinical–neurological characteristics in a group of patients
with mild head trauma.
Methods: A total of 352 patients with MTBI underwent olfactory function evaluation. The site of head trauma,
loss of consciousness <20 min, memory loss, subjective presence or absence of olfaction and other clinical,
neurological and radiological aspects were evaluated and compared with the olfactory dysfunction.
Results: A total of 33.5% patients enrolled in the study had an olfactory dysfunction. Eighty-seven
