| Summary: | Chronic rhinosinusitis is an inflammatory process involving the sinonasal mucosa, lasting 12 weeks or longer. It is often characterized by a complex of debilitating symptoms usually classified into minor and major symptoms. Estimating symptom/ disease severity using structured questionnaires can be challenging. This is especially so in rural areas where a combination of low literacy levels and language barrier may present communication difficulties. In view of the aforementioned challenges, it has become imperative to explore the correlation between the 22- item sino-nasal outcome test (SNOT-22) and a simpler means of evaluating symptom severity in chronic rhinosinusitis; hence this study. To determine the correlation between SNOT-22 and visual analogue scale (VAS) questionnaire scoring of symptom severity in chronic rhinosinusitis. This was a twelve month prospective cross sectional study of fifty- two consecutive newly diagnosed adult patients with chronic rhinosinusitis. Age of patients ranged from 19 – 91 years. Male to female ratio was 1: 1.26. There was a significant positive correlation between VAS and SNOT-22 in moderate and high symptom severity in patients with CRS. This study found a positive correlation between SNOT-22 and VAS scoring of disease severity in moderate and severe diseases and an insignificant correlation between these two instruments in mild disease. VAS can be used as a guide to symptom severity in the pre-treatment patients with CRS |
