Self-assessment of Olfactory Disorders for French Speaking Patients

Sense of smell disorders are common and are said to affect up to 20% of the general population. They are often disabling and have a real impact on the quality of life. Smell disorders are most often assessed using a visual analogue scale and more rarely with objective tests (Sniffing Stick Test). Many ENT units do not have these objective tests because they are time-consuming and are not covered by health insurance.

Some teams, such as that of Dr Thomas Hummel of the Carl Gustav Carus University Clinic in Dresden Germany, have developed self-assessment questionnaires for the sense of smell in order to improve the overall care of patients with olfactory disorders. Two of these self-questionnaires seem to us to be particularly relevant for use in everyday practice.

Since then, these questionnaires have already been validated in different languages (English, Chinese, Korean...), but have never been translated and validated in French. Translating and validating these questionnaires into French would make it possible to improve the management and follow-up of French patients with olfactory disorders and to assess the impact of loss of smell on their quality of life.

Behavioral

Assessment of sense of smell or loss of smell using an Analogue Visual Scale
Carrying out the objective smell test (Sniffin' sticks test) (gold standard)
Information from two self-questionnaires translated into French: a quality of life questionnaire (The Questionnaire Olfactory Disorders (QOD)) and a self-assessment questionnaire of his olfactory capacities (Self-Mini Olfactory Questionnaire (Self-MOQ))

Primary outcomes
