Abstract

Smell dysfunction is one of the main symptoms in chronic rhinosinusitis (CRS). Th erapeutic ultrasound (US) is suggested as a novel method for treating the CRS. No study has evaluated the eff ect of therapeutic US in CRS. Th e aim of this study was to demonstrate the eff ects pulsed ultrasound (PUS) in CRS subjects with olfactory dysfunction. Eleven CRS subjects with smell dysfunction (mean age 47.90�?±4.6 years; male 7; female 4) participated in a pretest-posttest study design with 2 measurements before and aft er 10 treatment sessions and aft er one month follow up. Participants received pulsed US (1:9), frequency 1 MHz, intensity/duration 1 W/cm2/5 minutes and 0.5 W/cm2/4 minutes for the maxillary and frontal sinuses, respectively. Subjects underwent for 10 treatment sessions, three days a week with US given every other day. Th e outcome measures were the Persian versions of SNOT-20 and University of Pennsylvania Smell Identifi cation Test (UPSIT). Th e repeated measures ANOVA were used for analysis. Th e mean changes of UPSIT scores (11/1 to 19/7) and SNOT-20 scores (41/4 to 19/6) were signifi cantly improved aft er PUS therapy (p<0.001). At one month fallow up, the improvements were sustained. Th e pulsed ultrasound was eff ective in improving smell dysfunction and symptoms severity in this sample of patients with rhinosinusitis.
