Abstract
Sinusitis is a very common acute or chronic illness that affects a significant percentage of individuals. Recently, therapeutic ultrasound was reported as a treatment for chronic sinusitis. The purpose of this study was twofold: 1) to evaluate the effectiveness of low-intensity pulsed ultrasound (US) in chronic sinusitis using a pretest-posttest research design and 2) to determine the level of association between the independent variables of initial presence of symptoms, age, gender, and duration of disease and the dependent variable of improvement of symptoms. Patients with chronic sinusitis were treated with low-intensity pulsed US, 3 days per week for 15 sessions. Fifty-seven patients (18 females and 39 males; mean age, 35 years) were included in the study. The results of the McNemar test showed a significant change in proportions of post nasal drip and nasal obstruction, two common leading symptoms of patients with chronic sinusitis (p < 0.001). Most of the major and minor symptoms showed significant changes after US therapy (p < 0.05). The total improvement of symptoms was 81.3. The greatest improvement in symptoms was observed in nasal discharge (100), followed by facial pain (95.4) and postnasal drip (82.7), three major factors in sinusitis. There was a significant, low association between the initial presence of symptoms and the improvement of symptoms after US therapy (�2 = 30.352; df = 12; p = 0.002; phi value = 0.356). A significant, low association was also noted between the age and the improvement of symptoms after intervention (�2 = 17.548; df = 6; p = 0.007; phi value = 0.270). It may be concluded that low-intensity pulsed US has a significant effect on chronic sinusitis and improves patient symptoms in our study group. Copyright © Informa Healthcare
