SNOT-22 score

Sinonasal symptoms

The 22-item Sino-Nasal Outcome Test (SNOT-22) measures the symptoms and impact of rhinosinusitis. It is used notably in the evaluation and monitoring of chronic rhinosinusitis. Its total score does not, on its own, establish a diagnosis of sinusitis.

QuestionnaireSNOT-22

SELF-QUESTIONNAIRE

Each item is scored from 0 to 5 based on the discomfort experienced over the past two weeks. The questionnaire assesses nasal, ear, and facial symptoms, sleep, as well as functional and psychological impact.

Are you patient?

You can complete the SNOT-22 yourself, taking the last two weeks into account. Your answers will help you discuss your symptoms and their impact with your healthcare professional.

Terms of contract

Keeping detailed answers helps you understand what has changed between two assessments. An overall decrease can hide a persistent difficulty that is significant for the patient.

Score interpretationSNOT-22

The sum of the 22 scores ranges from 0 to 110. A higher score reflects a greater impact.

Total score

First reading

  • 0 to 0

    No discomfort reported for any items on the scale (score of 0).

  • 1 to 110

    The impact is all the more significant the higher the total (1 to 110). This is a continuous measurement: the score alone does not provide a diagnosis.

The 2009 validation suggested a minimal important change of around 8.9 points in the context of surgical evaluation. This benchmark should not become a universal rule.

The questionnaire dimensions may be influenced by associated disorders. The total score does not locate the cause of the symptoms, does not replace an ENT examination, and is not sufficient to establish an indication for intervention. Comparisons require a consistent version and time period.
