METHODS: Seven hundred sixty-three adults were recruited from 8 Smell & Taste clinics Germany, Switzerland, Austria. Olfactory-related QOL was assessed by Questionnaire Olfactory Disorders (QOD). function “Sniffin’ Sticks” test; self-assessment performed visual analog scales. RESULTS: Patients post-infectious post-traumatic OD showed poorer than sinonasal idiopathic OD. The positively Sniffin’ Sticks test score, self-assessed function, disease duration, age, younger showing lower QOL. Female presented In addition, results that explained more variance evaluated test. CONCLUSIONS: addition psychophysical testing results, several such as cause, sex, or self- should be taken into account when assessing individual severity smell loss.
