Quality of life in patients with chronic rhinosinusitis: a validation of the Czech version of SNOT-22 questionnaire
Abstract
Quality of life (QoL) is defined as the difference between expectations and experience. A part of the overall QoL is health-related quality of life (HRQoL), which is influenced by the health of patients and can be changed through treatment.
Since the 1990s, there have been increased efforts to evaluate QoL of patients in all medical fields. Tools used to evaluate QoL are either generic health instruments for assessing general conditions or iseasespecific questionnaires focused on symptoms of a disease.
Chronic rhinosinusitis (CRS) is a disease characterized by a high prevalence and significant reduction in QoL. Although today there are many diagnostic methods for evaluating sinonasal disease, it cannot be said that the results clearly correlate with QoL, as it is perceived by patients.
