“…In addition, patients were asked whether systemic medication was needed to control the symptoms, including a course of antibiotics or corticosteroids in the last 3 months, or a need of long‐term antibiotics or corticosteroids in the last month. Based on the scheme in the update on EPOS in 2012, CRS patients were defined as well, partly or not controlled 1.The SNOT‐22 questionnaire is a validated 22‐item questionnaire, which is a disease‐specific, health‐related quality‐of‐life measure for rhinosinusitis 7.

RationaleThe European Position Paper on Sinusitis (EPOS) guidelines provide composite criteria to evaluate chronic rhinosinusitis (CRS) control, taking into consideration the severity of patients’ symptoms, aspect of nasal mucosa and medical intake as parameters of CRS control.ObjectivesTo study the degree of CRS control using novel EPOS control criteria at 3–5 years after a functional endoscopic sinus surgery (FESS) and correlate these data to symptoms scores.MethodsAdult CRS patients (n = 560) who had undergone bilateral FESS for chronic inflammatory sinonasal disease 3–5 years prior to the study were included. Patients received a postal questionnaire asking for control items according to EPOS control criteria, visual analogue scale (VAS) scores for total and individual sinonasal symptoms, sinonasal outcome test (SNOT)‐22 and Short Form (SF)‐36 questionnaires.Measurements and main resultsAbout 19.5% of CRS patients were well controlled, with 36.8% of patients being partly controlled and 43.7% uncontrolled. The levels of control corresponded to mean total VAS, SNOT‐22 and SF‐36 scores. Subgroup analysis revealed that female gender, aspirin intolerance and revision FESS were associated with higher prevalence of uncontrolled CRS, whereas allergy, asthma and smoking status did not alter the percentage of patients in each category of control. In 81 patients attending the outpatient clinic, nasal endoscopy changed classification in only four patients (4.9%).ConclusionsBased on the novel EPOS control criteria, at least 40% of CRS patients are uncontrolled at 3–5 years after FESS. Therefore, better treatment strategies leading to higher disease control are warranted in CRS care.

“…According to this definition, physicians and other healthcare professionals may describe the health status of each individual, but it is only the patient, individually, who can describe his/her own quality of life 2 . Chronic rhinosinusitis (CRS), with or without nasal polyps, is a prevalent disease, which can affect up to 14% of the North-American population, and cause a significant impact on quality of life 3 . Such impact may be demonstrated using quality of life questionnaires, such as the SF-36; and patients with CRS have impacts on physical pain and on social aspects which are even greater than patients with angina, congestive heart failure and chronic obstructive pulmonary disease 4 .…”

Qual ity of life questionnaires have been increasingly used in clinical trials to help establish the impact of medical intervention or to assess the outcome of health care services. Among diseasespecific outcome measures, SNOT-22 was considered the most suitable tool for assessing chronic rhinosinusitis and patients with nasal polyps. Aims:To perform translation, cross-cultural adaptation and validation of the SNOT-22 to Brazilian Portuguese. Methods:Prospective study involving eighty-nine patients with chronic rhinosinusitis or nasal polyps submitted to functional endoscopic sinus surgery, who answered the questionnaire before and after surgery. Furthermore, 113 volunteers without sinonasal disease also answered the questionnaire. Internal consistency, test-retest reliability, measure validity, responsiveness and clinical interpretability were assessed.Results: Mean preoperative, postoperative and no sinonasal disease scores were 62.39, 23.09 and 11.42, respectively (p<0.0001); showing validity and responsiveness. Internal consistency was high (Cronbach's alpha = 0.9276). Reliability was sufficiently good, considering inter-interviewers (r=0.81) and intra-interviewers within a 10 to 14 day-interval (r=0.72). Surgery effect size was 1.55. Minimally important difference was 14 points; and scores up to 10 points were considered normal. Conclusion:The Brazilian Portuguese SNOT-22 version is a valid instrument to assess patients with chronic rhinosinusitis and nasal polyps. Braz J Otorhinolaryngol. 2011;77(5):663-9. ORIGINAL ARTICLE
