Questionnaire of Olfactory Disorders
The Questionnaire of Olfactory Disorders (QOD) is a self-report instrument assessing the subjective impact of olfactory dysfunction on quality of life and daily functioning. Derived from olfactory research standardized testing (Sniffin' Sticks) and adapted for clinical use, the QOD measures perceived smell loss, changes in taste (retronasal olfaction), and emotional consequences of anosmia or hyposmia. It is increasingly used in otolaryngology, post-viral olfactory loss assessment, and chronic rhinosinusitis programs to quantify disease burden and monitor treatment response.
