Castro A, Furtado M, Rego A, et al. - Researchers conducted the study for analyzing the 4-year outcomes and effectiveness of balloon sinuplasty in the treatment of chronic rhinosinusitis (CRS). Data from 82 patients with chronic rhinosinusitis without nasal polyps (CRSsNP) and from 28 patients with nasal polyps (CRSwNP) were obtained. Data reported that the mean baseline SNOT-22 score was of 50.26 ± 15.33 for patients with CRSsNP and 52.25 ± 18.06 in CRSsNP patients. In the patient's symptom score, nasal endoscopy scores and imaging scores, significant improvements were recorded at all time points. For the treatment of CRS with great long-term outcomes, balloon sinuplasty seems to be effective and safe.
