We set out to determine the psychometric validation of a disease-specific health related quality of life instrument for use in chronic rhinosinusitis, the 22 item Sinonasal Outcome Test (SNOT-22), a modification of a pre-existing instrument, the SNOT-20. ⋯ We have found the SNOT-22 to be valid and easy to use. It can be used to facilitate routine clinical practice to highlight the impact of chronic rhinosinusitis on the patient's quality of life, and may also be used to measure the outcome of surgical intervention. The minimally important difference allows us to interpret scores in a clinical context, and may help to improve patient selection for surgery.
