Abstract

Acute otitis externa is an inflammation of the external auditory canal known as “swimmer's ear”. Direct costs including medical treatment, painkillers, antibiotics, steroids or both and indirect costs are also remarkable. Aim: The aim of this study was to compare the effect of boric acid and polymyxin, neomycin and hydrocortisone composition in the treatment of acute otitis externa. Materials and Methods: This randomized clinical trial was carried out on 80 patients aged more than 17-year-old who were referred to Kashani hospital clinic with a diagnosis of acute otitis externa by otolaryngologist. The patients were randomly allocated to two groups (A: Boric acid and B: polymyxin NH ear drops) and Painkiller was prescribed and administered orally for all patients and in the presence of fever, cellulitis around the ears and neck adenopathy, broad-spectrum systemic antibiotics were used besides topical treatment. Symptoms of patients who were evaluated by a physician includes pain, discharge from the ear, swelling of the ear canal, auricle swelling, tenderness, and ear itching. In addition, pain was evaluated in patients and was recorded by Macgill Pain Questionnaire, in the first, third, seventh and tenth days. Results: Results showed that itching on third day (p=0.007) and swelling of the ear canal in the examination of the third day (p=0.006) and the seventh day (p=0.001) in the polymyxin NH group is more than those of boric acid group. Overall mean pain based on McGill questionnaire was 11.10±1.49 in boric acid group in the examination on the first day and was 4.05±0.22 in the examination on the tenth day and in the polymyxin NH group, it was 10.9±0.99 on the first day and 4.20±0.40 on the tenth day. In both groups, pain relief was the same and there was no significant difference between two groups (p=0.075) Conclusion: The findings of this study showed slight differences in the effectiveness of the boric acid drug and combination of polymyxin, neomycin and hydrocortisone in the treatment of patients with acute otitis externa that is clinically of significance and considerable.
