RESUMO
@#BACKGROUND. Chronic rhino-sinusitis (CRS) is a common inflammatory disease of the nose and paranasal sinuses, especially after virus infections. It has a significant impact on patients’ quality of life. We aimed to evaluate the clinical value of low-level laser therapy (LLLT) forpediatric chronic rhino-sinusitis. METHODS. 30 patients 6-15 years old with CRS were divided into two groups: T1 were treated twice a week and T2 were treated five times a week for 2 treatment sessions within 2 weeks. Laser irradiation was delivered on 12 points over each maxillary and frontal sinuses with 30 seconds and the total treatment duration was 180 seconds. The evaluation was performed by a total symptom score based on SNOT-22 questionnaires of pre and after treatments. RESULTS. The total symptom scoreimproved significantly (p<0.15) in 27 cases. CONCLUSION. This study indicates that LLLT applied for 4 weeks improves symptoms in patients with CRS. LLLT is one of the most cost-efficient and painless treatment methods for pediatric rhino-sinusitis.
